Lubricated Plug Valve

Introduction of Lubricated Plug Valve

Lubricated Plug Valve delivers the high level of performance you have come to expect. Principle applications include natural gas, propane gas, digester gas, liquid asphalt, HVAC balancing, ore slurries, and various other industrial services. 

Lubricated Plug Valves deliver cost effective quick opening and closing with a tight, leak-proof closure. They are available in standard rectangular port, full rectangular port, full round port, diamond port and multi-port designs. Available end connections are threaded (1/2”-4”) and flanged (1”-24”). Consult factory for applicable models and sizes.
