Inverted Pressure Balance Lubricated Plug Valve

GMK Inverted Pressure Balance Lubricated Plug Valve is well-designed, performs its job as intended, has a solid seal, and efficiently blocks out moisture. It makes use of a flip-chip design, which enables the pressure and the light to be turned on and off in an independent manner; An oil groove is installed in the space between the valve body and the sealing surface so that the sealing ability may be improved. Users have some wiggle room when it comes to deciding which part material to use and which flange size to go with in light of the operating environment that exists at the moment. We produce our products to meet the requirements of a diverse set of technological applications.

The inverted Pressure Balance Lubricated Plug Valve has a chamber, and it will be positioned in the exact middle of the plug’s longitudinal axis. The aperture that s located at the bottom of the cavity is closed up, and a fitting for the injection of a sealant is fitted at the top of the cavity. Inverted Pressure Balance Lubricated Plug Valve prevents the sealant from leaking out of the space.


  • It is possible to permanently seal the plug off from the body by using a sealant. This will ensure that there are no leaks on the inside of the device.
  • It stops rust on the seating surface, making it more pleasant to sit on, and it also prevents corrosion.
  • In addition to this, it lubricates the valve, which makes it simpler and quicker to turn.
  • The lubricant’s pressure momentarily dislodges the plug from its location, which enables the plug to be rotated without any difficulty.
  • Additionally, the high pressure ensures that there will be no particles stuck between the valve body and the stopper under any circumstance.
