Introduction
Scope of the Manual

Figure 1. Type 1290 Vapor Recovery Regulator

complete with a Type 1098-EGR main valve, a
Type Y291A or Y291AL pilot and a Type 95H supply
pressure regulator. Detailed instructions for installation,
adjustment and maintenance of other equipment used
with this regulator are found in separate manuals.

Product Description
The Type 1290 vapor recovery regulator is a
self-contained, pilot-operated regulator system used for
vapor recovery of blanketing gas. When blanketing gas
pressure inside the vessel rises due to thermal heating
or pump-in operations, the Type 1290 regulator senses
an increase in vessel pressure and vents excessive
internal tank pressure to a vapor recovery storage tank.

Principle of Operation
The Type 1290 vapor recovery regulator serves as
a vessel vapor recovery system. The Type 1290
regulator controls vessel blanketing gas pressure
when the vessel is being filled with fluid or when
ambient temperature causes the vapor gas to expand.
The system monitors the increasing blanket pressure
and throttles open to pass excess blanketing gas into
a vapor recovery system thus controlling the desired
set pressure of the vessel.

Note
The Type 1290 is used as part of the
gas blanketing system to control the
outflow of blanketing gas under normal
conditions and to collect vessel vapors
for the vapor recovery system. It is not
an ASME safety relief device. You should
provide alternate methods of emergency
overpressure protection.
3

Type 1290
The Type 1290 vapor recovery regulator responds to
any changes in the blanket gas pressure and throttles
open or close to control the flow of the blanket gas out
of the vessel. A vacuum source on the outlet of the
regulator is necessary to ensure flow of low-pressure
blanket gas out of the vessel and into a vapor recovery
system. The higher the vacuum source, the more the
flow capacity of the vapor recovery regulator.
The pressure of the blanket gas registers under the
diaphragm of the pilot. A Type 95H regulator provides a
constant loading pressure source to the Type 1098-EGR
main valve actuator. When the pilot is closed, the loading
pressure fills both sides of the Type 1098 actuator through
a fixed restriction.
The Type 1098-EGR main valve spring keeps the main
valve plug tightly shut. When the vessel blanket gas
pressure reaches the setting of the pilot spring, the
pilot diaphragm moves, opening the pilot valve disk
and exhausting some of the Type 1098-EGR’s actuator
loading pressure through the pilot orifice. This typically
happens when the vessel is being filled with liquid.
The small fixed restriction maintains a higher loading
pressure on the bottom of the Type 1098 actuator. The
pressure differential across the main valve diaphragm
moves the diaphragm upward causing the main valve
to open which allows the blanket gas to flow out to
the vapor recovery system vacuum source, hence
controlling the vessel blanket pressure.
When the vessel blanket gas pressure begins to
stabilize, the pilot spring throttles and the pilot disk
closes. This allows the loading pressure source to fill
both sides of the Type 1098 actuator through the fixed
restriction. This equalizes the pressure acting on the
diaphragm, thus allowing the main valve spring to close
the main valve plug.

Installation and Startup
!

Warning

Personal injury, equipment damage or
leakage due to escaping accumulated
gas or bursting of pressure-containing
parts may result if this gas blanketing
system is overpressured or installed
where service conditions could exceed
the limits given in the Specifications
section and on the appropriate
nameplate, or where conditions exceed
any ratings of the adjacent piping or
piping connections.

4

To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by Title 49, Part 192,
of the U.S. Code of Federal Regulations,
by the National Fuel Gas Code Title 54 of
the National Fire Codes of the National
Fire Protection Association, or by other
applicable codes) to prevent service
conditions from exceeding those limits.
Additionally, physical damage to the
vapor recovery regulator system could
result in personal injury and property
damage due to escaping accumulated
gas. To avoid such injury and damage,
install the vapor recovery system in a
safe location.
Note
On the Type EGR main valve, normal
pressure drop assists shutoff, therefore,
leakage may result during any reverse
pressure drop condition.
1. Use qualified personnel when installing, operating
and maintaining regulators. Before installing, inspect
the main valve, pilot and tubing for any shipment
damage or foreign material that may have collected
during crating and shipment. Make certain that the
body interior is clean and the pipelines are free of
foreign material. Apply pipe compound only to the
external pipe threads with a threaded body, or use
suitable line gaskets and good bolting practices with
a flanged body.
Note
The Type 1290 vapor recovery regulator
should be installed as shown in Figure 1 so
that flow through the Type 1098-EGR main
valve matches the flow arrow attached to
the valve body.

!

Warning

A regulator may vent some gas to
the atmosphere. In hazardous or
flammable gas service, vented gas may
accumulate and cause personal injury,
death or property damage due to fire or
explosion. Vent a regulator in hazardous
gas service to a remote, safe location
away from air intakes or any hazardous
location. The vent line or stack opening
must be protected against condensation
or clogging.

Type 1290
2. To keep the pilot spring case vent from being
plugged or the spring case from collecting moisture,
corrosive chemicals or other foreign material,
point the vent down or otherwise protect it. For
proper operation, the Type Y291A pilot should be
installed with the spring case barrel pointed down
as shown in Figure 1. However, a Type 1290 with
a Type Y291AL pilot must be installed with the pilot
spring case barrel pointed up. To remotely vent a
Type Y291A or Y291AL, remove the vent (key 26)
and install obstruction-free tubing or piping into
the 1/4 NPT vent tapping. Provide protection on a
remote vent by installing a screened vent cap into
the remote end of the vent pipe.
3. Refer to Figure 2. Attach a 1/2 NPT upstream
pressure control line to the vessel using a straight
run of pipe. Connect the other end of the control line
to the Type Y291A or Y291AL pilot. Install a
1/2 NPT exhaust line between the pilot and vessel.
4. R
 un a supply pressure line (see Figure 2) to the
Type 95H regulator inlet (use 3/8-inch / 9.5 mm outer
diameter tubing or 1/4-inch / 6.4 mm pipe minimum).
Type 95H minimum supply pressure should be
10 psig / 0.69 bar higher than the set pressure of the
Type 95H regulator.

3. Open valve ‘E’ (if used). This valve must be a full
ported valve that will not restrict pressure registration.
Note
When opening valve ‘E’ in step 3, the
main valve may go wide-open if the vapor
pressure is higher than the pilot setpoint.
4. S
 lowly open valve ‘A’, introducing pressure into the
vapor recovery regulator system.
5. S
 lowly open valve ‘B’. The regulator will go into
immediate operation.
6. The control spring in the Type Y291A will be preset
at the factory if setpoint was specified. Otherwise,
the factory setpoint is approximately mid-range of the
spring. The spring range of the pilot is stamped on the
cap of the pilot.
Control spring adjustment may be necessary. To
check the setpoint, raise the vessel pressure while
observing a pressure gauge (manometer) and the
main valve travel indicator to determine whether or
not the setpoint is correct. On a Type Y291A, turning
the adjusting screw clockwise into the spring case
increases the pressure setting. On a Type Y291AL,
turning the adjusting screw counterclockwise out of the
spring case will increase the pressure setting.

Pre-startup Considerations
Before beginning the startup procedures in the next
section, make sure the conditions below are followed:
  •  Block valves isolate the regulator.
  •  Hand valves are closed.
  •  Gauges may be installed (if required) in place of
pipe plugs (key 52, Figure 11).
Note
For proper operation, the Type 95H supply
pressure regulator is factory set to the
values in the Specifications section.

Startup and Adjustment (Refer to Figure 2)
1. O
 pen valve ‘C’ to supply the energy source. The
Type 95H supply regulator has been preset at the
factory according to the control spring in the pilot.
If any field changes have been made, reset the
Type 95H outlet pressure. See Table 1 for the correct
pressure setting.

Note
One way to increase the vessel
blanketing pressure temporarily is
to manually push on the blanketing
regulator diaphragm. To push on the
diaphragm, remove the spring case
closing cap on the blanketing regulator
(Type Y690A, Y692, Y693 or Y291A
pilot) and use a screwdriver or rod to
temporarily push on the diaphragm
assembly and raise the outlet pressure
of the blanketing regulator. Release the
manual force on the diaphragm and the
blanketing regulator will return to its
original setpoint.

Shutdown
Installation arrangements may vary but in any
installation, it is important that the upstream block valve
should be closed first and that the upstream valves be
opened or closed slowly.

2. O
 pen valve ‘D’ (if used). This valve must have a
large port area and be fully open.

Type 1290
Maintenance
Regulator parts are subject to normal wear and must be
inspected and replaced as necessary. The frequency
of inspection and replacement of parts depends upon
the severity of service conditions or the requirements
of local, state and federal regulations. Due to the
care Regulator Technologies takes in meeting all
manufacturing requirements (heat treating, dimensional
tolerances, etc.), use only replacement parts
manufactured or furnished by Regulator Technologies.
The stem O-rings on the Type 1098 actuator can be
lubricated annually, using the grease fitting (key 28,
Figure 7). Line pressure leakage or unexpected grease
extrusion from the actuator vent (key 27, Figure 7)
during normal operation indicates stem O-ring damage.
All O-rings, gaskets and seals should be lubricated with
a good grade general-purpose grease and installed
gently rather than forced into position. Be certain that
the nameplates are updated to indicate accurately
any field changes in equipment, materials, service
conditions or pressure settings.

!

Warning

To avoid personal injury resulting from
sudden release of pressure, isolate the
pilot or regulator from all pressure and
cautiously release trapped pressure
from the pilot or regulator before
attempting disassembly.

Replacing Quick-Change Trim Package
Perform this procedure if replacing the entire trim
package (Figure 3). Key numbers for both the
complete main valve and its trim package are
referenced in Figure 6.
Note
All disassembly, trim change, and
reassembly steps in this section may
be performed with the regulator in the
main line.
1. Remove the cap screws (key 3) on a cast iron or
steel body, or remove the stud bolt (key 29, not
shown) on a stainless steel body. Pry the body flange
(key 2) loose from the valve body (key 1), and lift out
the trim package (Figure 3).

2. Perform any required inspection, cleaning or
maintenance on the exposed surfaces of the valve
body or trim package. Replace the gasket (key 4) or
cage O-ring (key 17) as necessary.
3. O
 n a pre-built replacement trim package, check
indicator zeroing by unscrewing the indicator protector
(key 19) and seeing if the flange of the flange nut
(key 22) lines up evenly with the bottom marking
on the indicator scale (key 18). If not, remove the
indicator scale and separate the flange nut and
hex nut (key 8). Hold the indicator scale against the
indicator fitting (key 5) with the scale base resting
against the shoulder of the fitting, and turn the flange
nut until its flange is aligned with the bottom scale
marking. Then lock both nuts against each other, and
install the indicator scale and protector.
4. Lightly coat the cage seating surfaces of the valve
body (key 1) web and the body flange (key 2)
seating surfaces of the valve body neck with a good
grade of general-purpose grease. Install the trim
package, and secure it evenly with the cap screws
or stud bolt nuts (key 29, not shown). No particular
trim package orientation in the body is required.

Replacing Trim Parts
Perform this procedure if inspecting, cleaning or
replacing individual parts in a trim package. Key
numbers are referenced in Figure 6. An exploded view
of a standard full-capacity trim package only is shown
in Figure 4.
Note
Access to the spring (key 9), indicator
fitting O-ring (key 21) or travel indicator
parts in step 1 can be gained without
removing the body flange (key 2).
1. Remove the indicator fitting (key 5) and attached
parts. Proceed to step 5 if only performing
maintenance on the fitting or attached parts.
2. Remove the cap screws (key 3) on a cast iron or
steel body, or remove the stud bolt (key 29, not
shown) on a stainless steel body, and pry the body
flange (key 2) loose from the valve body (key 1).
3. Use the valve body (key 1) as a holding fixture
if desired. Flip the body flange (key 2) over, and
anchor it on the valve body as shown in Figure 5,
removing the pipe plug (key 31) first.
4. To gain access to the port seal (key 12), upper
seal (key 15), or valve plug parts, unscrew the seat
ring (key 13) from the cage (key 11) and the cage

from the body flange (key 2). For leverage, insert
a wrench handle or similar tool into the seat ring
slots (Figure 5) and wrap a strap wrench around
a cage, or insert a soft bar through the windows
of the cage. Proceed to step 6 if no further
maintenance is necessary.
5. To replace the body flange (key 2) or gain access
to the spring (key 9), indicator stem (key 10),
stem O-ring (key 7), spring seat (key 28) or
E-ring (key 23), remove the indicator protector
(key 19) and indicator scale (key 18). Since some
compression is left in the spring, carefully remove
the flanged nut (key 22) and hex nut (key 8). Insert
a screwdriver through the press-fit retainer (key 6)
to remove the stem O-ring without removing the
retainer. If necessary, unclip the E-ring from the
indicator stem.
6. As required, replace and lightly lubricate the body
flange gasket (key 4), cage O-ring (key 17), seat
ring port seal (key 12) and the cage upper seal
(key 15). Install the dry port and upper seals in their
retaining slots with the grooved side facing out. After
the dry seals are installed into their retaining slots,
lightly lubricate the exposed portion of the seals and
apply a light coat of lubricant to the cage and seat
ring threads. Also lubricate any other surfaces as
necessary for ease of installation. No further main
valve maintenance is necessary if only the indicator
fitting and attached parts were removed.
7. Use the valve body as a holding fixture during this
step as shown in Figure 5. Insert the valve plug
(key 16) into the body flange (key 2). Then loosely
screw the cage (key 11) into the body flange and
slowly work the upper seal (key 15) by untightening
and tightening the cage. This will allow the upper
seal to be properly seated. Securely tighten the
cage using a strap wrench wrapped around the
cage. Loosely screw the seat ring (key 13) into

!

Warning

Before disassembling the regulator,
isolate it from the pressure system and
release all pressure from the regulator.
  1. Unscrew the valve plug guide (key 5) from the body
(key 1). The valve plug spring (key 10) and the
valve plug (key 4) will normally come out of the body
along with the valve plug guide.
  2. Inspect the seating surface of the valve plug (key 4),
being sure that the composition surface of the valve
plug is not damaged. Replace if damaged.

  6. Remove the diaphragm (key 12) and examine for
damage. Replace if damage is noted.
  7. With diaphragm (key 12) removed, check to be sure
the pressure registration hole is completely open and
free from all obstructions.
  8. Reassemble in the reverse of the above procedures.
Lubricate the upper spring seat (key 9) and the
exposed threads of the adjusting screw (key 15).
Before tightening cap screw (key 16) be sure to
install the adjusting screw, if completely removed,
and turn it down so that diaphragm slack is
obtained. This allows proper positioning of the
diaphragm (key 12) to permit full travel of the valve
plug (key 4). Complete reassembly procedures and
turn the adjusting screw to produce the desired
outlet pressure values shown in the Type 95H set
pressure specifications. Tighten the jam nut (key 17)
to maintain the desired setting.

Perform this procedure if changing, inspecting,
cleaning or replacing the actuator and/or the pilot
mounting parts. Key numbers are referenced in
Figures 7 and 11.
  1. The actuator and pilot may be removed and
replaced as a unit by disconnecting the Type 1098
loading pressure line.
  2. Access to all internal parts except the stem O-rings,
bearings and wiper ring (keys 6, 56 and 57,
respectively, Figure 7) may be gained without
removing the bonnet (key 3) or upper diaphragm
case (key 2) from the main valve. Disconnect the
pipe nipple (key 39, Figure 11) from the lower
diaphragm case (key 1, Figure 7).

  3. Inspect the seating edge of the orifice (key 3). If
damage is noted, unscrew the orifice from the
body and replace it with a new part. If no further
maintenance is required, reassemble the regulator
in the reverse of the above steps. When installing
the valve plug guide (key 5) coat the threads and
sealing surface with sealant to ensure an adequate
metal-to-metal seal.

  3. Remove the cap screws (key 10), nuts (key 11),
lower diaphragm case (key 1), diaphragm (key 7),
and diaphragm plate (key 8). To separate the stem
(key 12) from the diaphragm plate, remove the stem
cap screw (key 9).

  4. If diaphragm (key 12) damage is suspected, or to
inspect the diaphragm or other internal parts, loosen
the jam nut (key 17) and turn the adjusting screw
(key 15) to remove all spring compression.

To remove the stem O-rings, bearings and wiper
ring (keys 6, 56 and 57, respectively), remove the
loading and control lines. Unscrew the bonnet
(key 3) and remove the O-rings.

  5. Remove the diaphragm case cap screws (key 16)
and lift off the spring case (key 2). Remove the
upper spring seat (key 9) and regulator spring
(key 11). Remove the lower spring seat (key 8).

  4. To remove the case O-ring (key 5), unscrew the
four case cap screws (key 4), remove the upper
diaphragm case (key 2), and remove the case O-ring.

  5. Lubricate both stem O-rings (key 6) and wiper ring
(key 57), and install them with the stem bearings
(key 56) in bonnet (key 3). Lubricate the case O-ring
(key 5), and install it in the bonnet. Line up the holes

Type 1290
in the upper diaphragm casing (key 2) and the
bonnet; insert and tighten the four case cap screws
(key 4) to 24 to 30 foot-pounds / 33 to 41 N•m of
torque. Thread the bonnet into the main valve body
(key 1, Figure 6).
  6. Secure the diaphragm plate (key 8) to the stem
(key 12) with the stem cap screw (key 9). Lay the
diaphragm (key 7), diaphragm plate and stem
assembly into the lower diaphragm case (key 2)
so the diaphragm convolution laps up over the
diaphragm plate according to Figure 7. Install the
stem slowly up into the bonnet (key 3) to prevent
stem or O-ring damage, and secure the lower
diaphragm case to the upper diaphragm case
(key 1) with the cap screws and nuts. Tighten the
cap screws (key 4) and nuts using a crisscross
pattern with 24 to 30 foot-pounds / 33 to 41 N•m
of torque.
  7. Grease the stem O-rings (key 6) through the
grease fitting (key 28) until excess grease starts
coming out the vent assembly (key 27). Install the
pipe nipple and line tubing if they were removed
during maintenance.
