OPERATION

The Pow-R-Seal Gate Valve may be operated with a
handwheel or may be power actuated. With either
mode of actuation, open and close valve completely.
DO NOT THROTTLE FLOW. The valve, in good
condition, will seal pressures up to the maximum
allowable working pressure as a block valve, single
block-and-bleed valve or a double-block-
and-bleed valve.
Valves equipped with handwheels are CLOSED by
turning the handwheel CLOCKWISE until it becomes
tight. Tighten securely to mechanically energize
the seal. DO NOT BACK OFF THE HANDWHEEL. The
indicator rod at the top of the valve will move down
(towards the valve bore), as the handwheel is turned

ROUTINE MAINTENANCE

The following outlines the minimum scheduled
maintenance required for Pow-R-Seal Gate Valves
to promote trouble-free service and long life. Some
applications may require more maintenance.
Visually inspect every six months. See trouble
shooting section (page 13) for temporary solution to
problems. Operate the valve once a month, if
practical. A full open-close cycle is preferable.
Operate a partial cycle as a minimum.
Caution: Verify compatibility of any sealant,
lubricant, or anti-freeze with the trim of the valve
and product in the line.
Thermal Relief System Maintenance

CLOCKWISE. The valve is OPENED by turning the
handwheel COUNTER-CLOCKWISE until it contacts
the stop. The indicator rod at the top of the valve
will move up (away from the valve bore), as the
handwheel is turned COUNTER-CLOCKWISE.
When valves are equipped with power actuators,
the movement of the indicator rod will indicate if
the valve is being opened or closed. Make sure all
accessories recommended by the actuator
manufacturer are installed before valve actuator
installation. Should any maintenance be necessary,
obtain the part number from the unit's nameplate
and contact Cameron Valves & Measurement or the
nearest representative.
1.
Inspect relief systems at least twice a year
for any visual abnormalities such as damage
that may prevent the system from
functioning properly. Repair or replace, as
required to correct abnormalities.
2.
Check valves shall be tested periodically to
verify proper function. Follow local piping
codes and plant/facility maintenance and
safety procedures for the testing frequency.
Cameron Valves & Measurement
recommends testing check valves using the
same schedule for relief valves per ASME
B31.4 in the absence of local testing
frequency requirements. Make sure needle
valves in thermal relief systems are open
before returning the valve to service.
