DRAIN VALVE

After lengthy service, there is a possibility of water,

line scale, sediment or other foreign matter collecting

in the lower body cavity. It is advisable to periodically

drain the valve to discourage development of

conditions that can possibly lead to valve damage or

impair the operation of the valve. If draining is not

regularly scheduled, it is strongly recommended to

drain the valve at these times:

After hydrostatic testing.

After cleaning the line.

When valve cannot be fully opened or closed

(foreign matter in the bottom of valve

can not only prevent placing valve in a fully

closed position, it can also cause permanent

damage to the internal sealing surfaces). A

safety pressure releasing tool is required to

simplify the procedure of releasing body

pressure or draining the valve. To release

body pressure or to drain valve, first place the

valve in closed position.

Warning: To avoid possibly being struck by liquid or

foreign solid matter, position yourself so the outlet

port of the grease fitting is pointing safely away from

you. (If the ball check is not holding pressure,

pressure will blow through the safety holes in the

cap.) Back-up the seat grease fitting using a wrench

so only the safety cap will be removed from the

fitting. Carefully remove the safety cap from the seat

grease fitting. NEVER remove the grease fitting with

the valve under pressure!

Carefully remove the safety cap of the lower drain

grease fitting. Contact your local Cameron Valves &

Measurement representative for further assistance, if

needed. Back out the stinger of the pressures releas-

ing too until it stops. Install the pressure releasing tool

onto the uncapped grease fitting. Carefully screw the

stinger of the releasing tool - (until the ball check

in the grease fitting is pushed off its seat). This will

allow the valve to drain or to release body pressure.

After completion, back out the stinger of the pressure

releasing tool to allow the ball check in the grease

fitting to reseat and permit easy removal of the

pressure releasing tool. Replace safety cap on the

lower drain grease fitting.
