Valve plate rubber gasket
Valve plate rubber gaskets are commonly used in various valve types to provide a sealing function. The following are some common valve types in which valve plate rubber gaskets are used:
Globe Valve
The valve plate rubber gasket is located between the valve plate and the valve seat. When the valve is closed, the rubber gasket is filled between the valve plate and the valve seat to achieve sealing.
Check Valve
The valve plate rubber gasket is used to prevent the reverse flow of the medium. In a check valve, a gasket is located on the valve disc or valve seat. When the medium flows back, the gasket is pushed open to allow the fluid to pass, and when the medium flows normally, the gasket seals to prevent reverse flow.

Pressure Relief Valve
The valve plate rubber gasket is used to control the release of pressure. When the pressure exceeds the set value, the valve plate rubber gasket will open, allowing part of the medium to flow out to relieve the pressure on the system.
Control Valve
In some control valves, the valve plate rubber gasket is used to control the flow and pressure of the medium.
Butterfly Valve
The valve plate rubber gasket is often used in the sealing part of the butterfly valve. When the valve is closed, the gasket is filled between the valve plate and the valve seat to ensure sealing performance. The rubber gasket on the butterfly valve is a specially designed sealing element, which is mainly used for the sealing part of the butterfly valve. The following is a detailed introduction to the rubber gasket on the butterfly valve:
Function: The main function of the rubber gasket on the butterfly valve is to provide the sealing performance of the valve. When the butterfly valve is closed, the rubber gasket acts as a sealing gasket and is filled between the valve plate and the valve seat to prevent medium leakage.
