Inverted pressure balance lubricated plug valve according to ANSI is applicable to the cutting and connection of pipelines medium that aroused in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc. It is used under nominal pressure of CLASS150-1500LBS, and works at the temperature of -29~180℃. a. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
Pressure balance lubricated plug valves are metal seated valves providing a tight shut off ( 0 leakage ) sealing, valves shall be regularly lubricated along with their operation by injection of suitable grease.
We manufacture some of the most dependable cast and forged steel Pressure Balance Lubricated Valves in the industry. Our Valve Lubricated Type Plug Valves are available in Short, Regular, and Venturi Pattern. The different patterns vary as regards end to end dimension and port area for a given size of valve. Regular Pattern valves have the largest port area. Short Pattern valves have a reduced port area as a consequence of their compact face-to-face dimensions which are identical to those for wedge gate valves. Venturi Pattern valves have a reduced port area and a flow path approximating a venturi shape to aid pressure recovery.
It has logical structure,reliable seal,excelient performance and nice design. It has the structre of flip-chip balanceable pressure and ligh on/off operation. An oil groove is set between valve body and seal surface,which may infuse the seal grease to increase the seal capablility. he paryt material and flange dimension may be selected according to current operating condtion and users requirement.so that meet the requirements of various engineering.
