Plug Valves Video

The plug valve employs the plug with through hole as the opening and closing part, realizing opening and closing by the rotation between the plug and the valve.

Our company has developed a new type of plug valve for severe corrosion, high temperature, high pressure and other harsh conditions. The new plug valve employs trunnion double gland structure, being able to fit the harsh working conditions in petroleum, chemical and smelting industries, ensure long-term safe and stable operation of process pipeline equipment, and avoid the internal and external leakage of traditional plug valves in pipelines.
