Plug Valves

PV Series plug valves are designed to provide positive shut-off up to 3000 psig.  Plug valves provide low-torque, quarter-turn actuation making them an ideal solution where repeated manual actuation is required.  Plug valves are compact and lightweight.  Their compact size allows them to be mounted close together in distribution manifolds and other applications where space is at a premium.

Quarter-Turn Plug Valve F&B

Plug Valve Applications

Quarter-turn plug valves are used in a wide range of industries.   Low torque makes them a favorite for applications requiring frequent manual actuation.  They can be used as isolation valves and vent valves in to control valves, in laboratories for air systems, gas selection manifolds, gauge isolation, and drain valves. They can often be a less costly alternative to pipe ended ball valves.  

Quarter-turn plug valves are designed to allow throttling to control flow and to create "soft" actuation in systems where designers desire both the softer application provided by needle valves with the quarter turn simplicity and higher flow of a ball valve.

Plug valves are available with a downstream vent.  This will safely isolate the pressure source, and equally as important vent the downstream pressure so that devices such as pneumatically operated spring return valve package can be maintained more safely.
