Principle and application scope of Inverted pressure balance lubricated plug valve from China Lubricated plug valve manufacturer :
Inverted pressure balance lubricated plug valve Working principle:
The plug of Inverted pressure balance lubricated plug valve is adjusted by the bolt in the cover, the sealant is injected into the valve body from the end of the stem;In order to prevent pressure will plug into the valve body, the end of the plug has a balance hole, and the balance hole at the small end of the plug has no medium can only to the small end of the check valve, it can make the pressure into the plug at both ends of the cavity, Inverted pressure balance lubricated plug valve seal by the plug and the sealing agent between the valve body for sealing.
Inverted pressure balance lubricated plug valve Application:
Inverted pressure balance lubricated plug valve is suitable for engineering pressure class CLASS150 -- 900LB, PN10 -- PN150, working temperature -29 -- 150℃ natural gas pipeline.
Inverted pressure balance lubricated plug valve Main structural features:
1. Exquisite product structure, long sealing life, superior performance, modeling in line with the process aesthetics.
2. Flip balance structure, light switch, can be made into high pressure level.
3. The Inverted pressure balance lubricated plug valve can be installed in all directions and is not controlled by the direction of installation;The valve is small in size and does not require special installation space.
4. Inverted pressure balance lubricated plug valve can be used for two-way flow.
5. There is an oil groove between the valve body and the valve plug, which can inject sealing grease into the seat through the oil nozzle at any time to increase sealing performance.
