RE: gate valves for control sets on gas lines
you are very funny. it is an 8 inch line and is the outlet from a oil-gas separator. the isolating valves are part of the PSV's control set. i dont know whether a gate valve can be tightly sealed or not.
thanks farzin.
RE: gate valves for control sets on gas lines
If an 8-inch gate valve ever completely seals, it is a coincidence. They are not made for a bubble-tight seal and I would never consider one for an isolation under a PSV.

Use a reputable manufacture such as Crane, Velan, Powell, Bonne Forge and you'll be fine as long as the metalurgy matches the service.
If the service is high pressure and you really want to get as close to 100% isolation as reasonably feasible, then spec out an Orbit Valve. http
