Pressure Balanced Plug Valve

Pressure Balanced Plug Valve

Pressure balance lubricated plug valve is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, electric power industry etc under nominal pressure of Class 150 - 900 Lbs and working temperature of -29 - 180°C.

1. It has logical structure, reliable seal, excellent performance and nice design.

2. It has the structure of flip-chip balance-able pressure and tight on/off operation.

3. An oil groove is set between valve body and seal surface, which may infuse the seal grease to increase the seal capability.

4. The part material and flange dimension may be selected according to current operating condition and user’s requirement, so that meet the requirements of various engineering.
