Inverted Pressure Balance Lubricated Plug Valve with Extension Stem

Inverted Pressure Balance Lubricated Plug Valve with Extension Stem

A cavity in the middle of our lubricated plug valves contains a sealant that moves toward the radial holes, creating a renewable seal between the plug and body when operated. The sealant can also act as a lubricant that reduces friction to elongate the plug valve’s lifespan. Lubricated Plug valve setup are ideal for Petroleum, chemical, pharmaceutical, fertilizer and electric power industries etc.

With dedicated workshops and superior mold casting capabilities, LIXIN is sure to meet your plug valve needs.
