FULL PORT GATE VALVE

FULL PORT GATE VALVE

FULL PORT GATE VALVE

(OP)
I have a question about API 600 Standard. I have to issue a Data sheet for Gate Valves 2"-6" (API 600 Standard). If I want a Full port valve, I need to specify this characteristic or all API 600 Gate Valves are Full Port.

RE: FULL PORT GATE VALVE

Specify it.

Thanks for your help. The application of this valve is on PSV outlet, is correct to use a Gate valve in this situation or is better to use a Ball Valve Full Bore. I think that ball valve is easier to support and to maneuver for the operator.

RE: FULL PORT GATE VALVE

Is it not criminal in a way?

RE: FULL PORT GATE VALVE

It is NOT recommended to put a valve in any relief line.  It is ONLY permitted to put a valve in a relief line when that valve can be LOCKED OPEN and is locked open whenever it is protecting an operating line.

In this case a gate valve might be better, since it takes more turns to close than a ball valve.  The harder it is to close, the more chance nobody will close it.
