Cast steel swing check valve H44H-16C

H44HSwing Check ValveAdopting internal rocker arm rotary opening structure, all opening and closing parts of the valve are installed inside the valve body, without penetrating the valve body, except for the middle flange part with sealing gasket and sealing ring, there is no external leakage point in the whole. Widely used in chemical industry, metallurgy, pharmaceuticals and other fields.

Working Principle

H44H rotary check valve adopts internal rocker arm rotary structure, the valve flap rotates around the rotary axis, the valve flap opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure of the inlet side is lower than that of the outlet side, the valve flap closes automatically under the effect of fluid pressure difference, gravity and other factors to prevent backflow of fluids.

Product Features

• Used in water supply and drainage, fire fighting, HVAC, industrial and other systems.

• It can effectively reduce water hammer pressure, has good sealing performance, and closes without noise.

• The fluid-type water circuit with internal fluid conductors is designed to ensure minimal pressure loss.

• Installed at the outlet of the pump can be quickly closed before the water flow backflow to avoid water hammer, water percussion sound and broken ping impact to prevent backflow and protect the equipment.
