Storage
After valves are assembled and tested, they are
placed in the full open position, flange seal
surfaces and bores are greased and end protec-
tors are installed. This will provide adequate
protection for indoor storage. Extended outdoor
storage requires periodic inspection and the
addition of a corrosion inhibitor. Contact your
Cameron representative for extended storage
guideline. Valves should only be stored in the full
open or full close position to prevent seat distor-
tion.
Installation
DynaSeal 310C 3-piece ball valves may be installed
in any position with flow from either direction.
However, for best service life there is a preferred
vertical or horizontal position to maximize
sealing and minimize the accumulation of sedi-
ment. In the vertical position it is preferred to
have the upstream pressure from above so the
weight of the ball will assist the pressure in
sealing. With the run of the valve in a horizontal
position, it is preferred to have the stem lying
horizontal (i.e. toward the viewer) with pressure
from the right. During operation, flow will act as
a siphon and minimize retention of sediment.
When handling or installing a valve, keep the
valve in the full open position whenever possible
to prevent foreign object damage to the ball.
Threaded-End valves are installed using two pipe
wrenches, one on the flats of the tailpiece adja-
cent to the pipe being installed and the other on
the adjacent pipe. DO NOT apply wrench to the
body section or opposite side tailpiece as this may
result in the tailpiece turning and transmitting
torque to the valve body.
Socket Welded-End – To prevent ball and seat
damage due to excessive heat or weld slag, the
following procedure is recommended for welding
DynaSeal 310C valves into a line:
1. Use solvent to clean grease or rust inhibitor
from the ball and/or bore of the valve.

2. Electric welding equipment is preferred for all
installations. However, if only oxygen-
acetylene welding equipment is available,
extreme caution should be taken regarding
excess welding temperature.
3. Weld with ball in the “Full Open” position.
4. Make sure temperature of body/seat area
does not exceed 250 F (Check with a Tempil
stick).
5. Avoid rapid application of excess welding
material. Weld each end of valve with a
continuous bead using a 1/8 in. maximum
diameter electric welding rod.
Thoroughly clean (by pigging and/or flushing)
weld slag from valve bore and line before turning
ball to closed position.
Flanged-End valves may be bolted into the line
using two open or boxed end wrenches.
1. Threads of flange bolts and nuts should be
lubricated to obtain maximum loading of
bolts.
2. Finger tighten all nuts first.
3. When tightening bolts, use the crisscross
method and torque each bolt to ANSI or
gasket manufacturers specifications.
Field testing, if performed after the valve has
been properly installed into the line, should be
done in accordance with the following procedure:
Caution: Ensure that all test fluids contain
corrosion inhibitors and are compatible with
valve seat and seal material.
1. Preliminary Testing – Completely flush the
system or the line to minimize damage to the
seats and ball surface which might be caused
by weld slag or other foreign matter resulting
from installation procedures.
2. Line Testing – When performing this test, the
valve should be in the half-open position to
ensure that the body cavity is completely
filled with the test media and to prevent
accidental over pressure of the seats. NOTE:
Line may be tested at a maximum of 1 1/2
times the valve’s cold working pressure rating
without consulting the factory.
3. Seat Testing – When testing the seats with the
valve in the closed position, do not exceed
the valve’s cold working pressure rating.
4. Upon completion of testing, purge all test
fluids from the valve.
Operation
DynaSeal 310C ball valves operate from fully
open to fully close by a 90 degree turn of the
handle. The handle aligned with the pipe always
means the valve is open and with the handle
perpendicular to the pipe means the valve is
closed. Additionally, the stems have flats that
align the handle and can be used to indicate ball
position. The bore of the ball is parallel with the
faces of the stem flats.
DynaSeal 310C valves may be power actuated.
Pneumatic and hydraulic actuators, whether of
the fail-open, fail-close, or fail-last position type,
have “OPEN – CLOSE” indicators on the top of
each unit. On a pneumatic actuator, make sure
filters and lubricators (if recommended by the
actuator manufacturer) are installed prior to
valve and actuator installation. Should any
maintenance be necessary, obtain the part
number from the unit’s nameplate and contact
Cameron or the nearest representative.
Routine Maintenance
Due to its design and simplicity the 310C ball
valve requires very little maintenance. Its non-
lubricated, self-cleaning ball can provide reliable,
leak free performance over a long period of
time.
The only preventative maintenance recom-
mended is to periodically inspect the valve for
leaks around the stem or actuator. Should a leak
be noticed, the following procedure is for
adjusting the packing.
Stem Packing Adjustment –
1. With an Allen wrench, snug up each of the
two packing adjustment screws in a clockwise
direction.
2. Snug up each screw an equal amount only as
much as required to stop the leak, not to
exceed the maximum specified in the follow-
ing table.

Warning: Valves should be placed in a partially open position prior to working on a valve or
removing it from service to vent pressure or drain product that may be trapped in the body
cavity. When removing threaded end valves from the line, apply wrenches in the same manner
used for installation and NOT to the valve body section or opposite side tailpiece as this may
result in breaking loose the threaded tailpiece to body joint.
Trouble Probable Cause Remedy
Will not open or close

temperatures.
b. Pressure locked. (Condition in which
the body pressure exceeds the line

Torque values above this indicate seals are
worn and need replacement and excessive
tightening will also cause an unacceptable
increase in valve stem torque.
