Cast Steel Stainless Steel Vertical Type DRVZ Slient Check Valve

Product introduction:

The H42H series vertical check valve can prevent medium backflow and play a medium check role. The H42H vertical check valve is in an open state when the inlet pressure is higher than the outlet pressure. Due to the pressure of the medium at the inlet end of the pipeline, the valve disc in the top opening check valve automatically opens; When the pressure of the medium at the inlet end is low at the outlet end, the spring pushes the valve disc towards the valve seat, causing the valve to close and preventing the medium from flowing back.

The H42 series vertical check valve can be installed horizontally or vertically. If a spring is required for horizontal pipeline installation, a spring is not required for vertical pipeline installation. The valve disc will automatically close under its own weight and the pressure of the countercurrent medium.

Product technical paramters:

Product features:

1. The streamlined design of the valve body cavity reduces sharp bends, corners, and protrusions, thereby reducing fluid resistance.
2. The valve disc is designed with a conical shape before and after, which greatly reduces fluid resistance and reduces noise caused by turbulence.
3. The closing stroke of the valve disc is short, only 1/4 of the nominal diameter, which reduces the closing time of the valve disc and reduces the generation of water hammer.
4. The valve uses springs to accelerate the closing speed of the valve disc and reduce the generation of water hammer.
