Model 4055 Dual Chamber Orice Fittings
NuFlo Model 4055 Dual Chamber Orice Fittings are compact, streamlined and rugged featuring a simple
and rapid method for changing or inspecting orice plates under pressure. The orice ttings feature a
ball-type construction for opening and closing “without” a complicated gear mechanism.
The unique construction incorporating a ball closure with spring-loaded, self-lubricating, Moly-lled
Teon® oating seals eliminates any need for periodic lubrication. All NuFlo dual chamber orice ttings
are manufactured in accordance with ANSI and ATSM standards and available in 2”, 3”, 4” and 6” sizes.
Features
• Compact construction
• Rapid method for changing orice plates under pressure
• Self-lubricating Moly-lled Teon® seals (periodic lubrication not required)
• Orice plate O-ring seal provides positive seal around orice plate
• Positive orice plate alignment assured with closure of chamber lid and internal ball stop
Standard Specications
Meter Connections: All NuFlo orice ttings are provided with two sets of ange taps located 1” on each
side of the orice plate. Flange tap meter connections are 1/2” NPT, internal tap hole sizes follow latest
AGA/API recommendations. Internal edges of tap holes are free from burrs and slightly rounded.
Two types of NuFlo orice ttings are available:
• Flanged Type, either raised face or ring joint
• Flangeweld Type, having a weldneck inlet and a anged outlet

Installation and Maintenance
It is recommended that the NuFlo Dual Chamber Orice tting be placed in the line with the two 1/2”
NPT ange taps and instruction plate facing upward. The ow arrow cast on the body must correspond
with ow direction of line. The orice tting is shipped with an orice plate installed in operating posi-
tion. It is suggested that the orice plate be removed before ushing or purging the ow line.
The spring-loaded, self-lubricated Moly-lled Teon® ball seals eliminate any need for periodic lubrica-
tion. Grease is not required for sealing.
Operating Instructions
Removing an Orice Plate
1. Close main orice tting. This rotates the
orice plate out of operation and places the
bypass section into the orice tting bore.
2. Insure “EQUALIZER” valve is closed.
3. Open the “BLEED” valve. This vents the
pressure around the orice plate and chamber
lid.
4. Open the chamber lid by loosening the hinge
bolt cap nuts and removing the two top cap
nuts. This will allow the chamber lid to open
freely.
5. Remove orice plate and retainer with the
wrench supplied with unit.
Replacing an Orice Plate
1. Place orice plate and retainer into the ball
slot with “OUTLET” on plate holder facing
“OUTLET” stamped on body casting.
2. Close chamber lid and tighten the four cap
nuts.
3. Close “BLEED” valve.
4. Open “EQUALIZER” valve to equalize ball
seal pressure.
5. Open main orice tting. This places orice
plate into operation and removes bypass
section from the bore.
6. Close “EQUALIZER” valve.

a simplicity of design with a minimum number of parts. A quick and easy method for removing orice
plates minimizes shutdown time. The interchangeability of the orice plates and retainers between the
NuFlo Dual Chamber and Single Chamber orice ttings also provides an economy in inventory require-
ments.
Standard Specications
Single chamber orice ttings are available in angeweld and weldneck types. All NuFlo single chamber
orice ttings meet AGA/API specications. Two sets of 1/2” NPT ange taps are provided on all single
chamber orice ttings. They are available in 2”, 3” and 4” sizes.
When Ordering, Specify:
• Quantity
• Assembly part number
• Type of single chamber orice tting
(angeweld, weldneck)
• Service (sweet, (H2S) sour)
• Flange rating
• Flange type (raised face, ring type joint)
• Pipe schedule
• Orice plate bore size(s)
Installation and Maintenance
Install the NuFlo single chamber orice tting with the two 1/2” NPT ange taps and instruction plate
facing upward. The ow arrow cast on the body chamber lid must correspond with ow direction of line.
The orice tting is shipped with an orice plate installed. Remove the orice plate before ushing or
purging the line. Maintenance is minimal; lubrication is not required.
Operating Instructions
Removing Orice Plate
1. Depressurize line.
2. Open chamber lid by loosening the hinge bolt cap nuts and removing the two top cap nuts. This will
allow the chamber lid to open freely.
3. Remove orice plate and retainer.
Replacing Orice Plate
1. Place orice plate and retainer into the slot of the tting with “OUTLET” facing same direction as
ow arrow on chamber lid.
2. Close chamber lid and tighten the four cap nuts.
3. Pressurize line.

Meter Runs
The meter runs are fabricated by trained manufacturing personnel with complete facilities for machining,
welding, gauging and inspection. This produces a product with quality and metering accuracy not possible
with eld-fabricated units.
All meter runs are factory-aligned and welded with special equipment that guarantees a straight, smooth
meter run without defects. Standard lengths meet AGA/API requirements.
Meter Run Alignment
Orice tting to meter run alignment can be
specied with dowel pins. This option assures
proper bore alignment.

Orice Plate Assembly
The orice plate retainer assembly is used in both the dual and single chamber orice ttings. The orice
retainer and chamber lid are designed to assure the center alignment of orice bore with the line bore. The
chamber lid cannot be closed without centering the orice in the correct position. If the plate is not cor-
rectly centered, closing the lid will align the plate automatically. The plate retainer and the dovetail ring
are nickel plated for corrosion resistance.
The orice retainer, dovetail ring and O-ring
together hold the orice plate in a rigid
position and perpendicular to the bore at all
times.
Universal orice plates are stocked in 1/8-in.
increments, beginning at 0.125 inch. The
orice bore size and outlet are clearly etched
on each plate. All AGA/API requirements
are specically met.
The NuFlo orice plate is interchangeable
with other universal type plates. Standard
orice plates are constructed of 316 stainless
steel; however, they are available in other
material upon special request. Each orice
plate has a 15-30 micro-inch nish.

Straightening Vanes
The use of straightening vanes in meter runs serves a twofold purpose: (1) the turbulence often created
in a complex piping system is straightened and smoothed to a normal ow pattern and (2) the amount of
straight pipe required preceding an orice is reduced. Cameron offers both anged and pin type straight-
ening vanes.
Vanes are available with carbon steel, 304 or 316 stainless steel tubing welded together and securely at-
tached into the meter run. The tubes are reamed as thin as is practical at both ends and are constructed so
as to minimize the possibility of vibration. All vanes are manufactured according to the latest AGA/API
specications.

Installation
The ange type straightening vane is held in place
by a ange ring between two pipe anges.
The pin type straightening vane is held in place
by an allen set screw. The set screw seats into a
countersunk hole in the center of a welded pad
that is welded to the straightening vane itself. The
tapped hole in the pipe is sealed off by welding a
threadolet around the hole. A pipe plug is installed
into the threadolet.
