How to fix leakage around the stem of my Cameron TK valve?
If there is leakage around the stem of your Cameron Control Unit valve, disassemble and replace the O-rings.
Why is my Cameron TK valve hard to operate?
A hard-to-operate Cameron Control Unit valve can stem from several causes: the ball might not be properly aligned with the bores of seats; there could be erratic operation; ice may have formed in the valve operator; a build-up in the seat area may be present due to line contaminants; there might be restrictions in the bore of the valve, or the stop isn't set correctly; the actuator unit might be damaged; there could be a restriction of the pneumatic actuator vent, or a faulty power supply.
What to do if my Cameron Control Unit grease fitting is leaking?
If your Cameron Control Unit grease fitting is leaking, try these solutions: * Tighten the safety cap. * If the safety cap is damaged, replace it. * Inject a small amount of cleaner into the fitting to dislodge any trash.
What to do if Cameron TK valve will not seal?
If the Cameron Control Unit valve won't seal, try injecting valve sealant into the stem fitting (if present) or replace the stem O-ring. Alternatively, ice may have formed in the body of the valve; in this case, apply heat or inject antifreeze solution. Also, drain periodically to eliminate water accumulation.
What to do if Cameron Control Unit valve will not fully close?
Reset the actuator limit switches or stops for proper closing.
