Introduction for inverted Pressure plug valve

Inverted pressure balance lubricated plug valve acc.to ANSI is applicable to the cutting and connection of pipelines medium that are used in various industried such as petroleum,chemical industry,pharmacy,chemical fertilizer,electricpower industry etc under nominal pressure of CLASS 150-900lbs and working temperature of -29-180.


Features for lubricated plug valve :
1.It has logical structure,reliable seal,excelient performance and nice design.
2.It has the structre of flip-chip balanceable pressure and ligh 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 capablility.
4.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.

Bolted cover, structure of flip-chip balanceable pressure and light on/off operation. An oil grove is set between valve body and seal surface, which may infuse the seal grease to increase the seal capability.
