H74H Face-to-Face Circular Check Valve

【Check Valve】Working Principle: It is a valve that can automatically prevent the reverse flow of fluid. The valve disc of the check valve opens under the pressure of the fluid. The fluid flows from the inlet side to the outlet side. When the pressure at the inlet side is lower than that at the outlet side, the valve disc automatically closes due to the pressure difference of the fluid, its own gravity and other factors to prevent the reverse flow of the fluid. [Flanged Plate Type Check Valve] Installation Precautions: (1) Do not allow the check valve to bear weight in the pipeline. Large check valves should be independently supported to be unaffected by the pressure generated by the pipeline system. (2) When installing, pay attention to the direction of the medium flow should be consistent with the arrow direction on the valve body. (3) Lifting type vertical disc check valves should be installed on vertical pipelines. (4) Lifting type horizontal disc check valves should be installed on horizontal pipelines.

The H74H double-ended round check valve is a type of ultra-thin check valve. It features a simple structure, an attractive appearance, light weight, and easy installation. This valve is mainly applicable to water supply systems, petroleum, chemical, metallurgy and other industrial sectors for places with limited installation space.
