Inverted Pressure Balance Lubricated Plug Valve acc. to ANSI:

Our this kind valve which is applicable to cutting and connection of pipelines for various industries such as petroleum, natural gas, chemical, pharmaceutical, fertilizer, electric power and so on, under nominal pressure of class 150 to 1500 Lbs and working temperature from -29℃ to 180℃.

Features in Structure:
→ Logical structure, reliable seal, excellent performance and nice design.
→ The structure of flip-chip balanced pressure, on-off operation is light.
→ An oil nozzle is set between body and seal surface so as to infuse seal grease when needed, the seal capacity is increased.
→ Material of parts and dimension of flanges may be selected reasonably according to actual working condition and requirement from users, so as to meet various engineering demands.
