Balance Pressure Plug Valve
Introduction:
For the pressure balanced inverted oil seal plug valve, the position of the valve plug is adjusted by the bolt in the bonnet, and the sealant is injected into the valve body from the end of the valve stem; In order to prevent the pressure from pushing the valve plug into the valve body, a balance hole is opened at the end of the valve plug, while the balance hole at the small end of the valve plug has no medium and can only reach the check valve at the end of the small end, which can make the pressure enter the cavity at both ends of the valve plug, and the valve is sealed by the sealant between the valve plug and the valve body.
Scope of application:
Applicable to natural gas pipelines with engineering pressure class CLASS150-900LB, PN10-PN150 and working temperature of – 29-150 ℃.
Main structural features:
1. The product structure is exquisite, the sealing life is long, the performance is superior, and the shape conforms to the process aesthetics.
2. Inverted balanced structure, light switch, can be made into high pressure level.
3. The valve can be installed in all directions without being controlled by the installation direction; The valve is small and has no special requirements for installation space.
4. The 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 valve seat at any time through the nozzle to increase the sealing performance.
