304 Stainless Steel Swing Check Valve H44W-16P

H44W rotary check valve adopts internal rocker arm rotary structure, all the opening and closing parts of the valve are installed inside the valve body, do not penetrate the valve body, in addition to the middle flange parts with sealing gasket and sealing ring, the whole has no external leakage point. Widely used in chemical industry, metallurgy, pharmaceuticals and other fields.

Working Principle

H44W 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

• For use in water supply and drainage, fire protection, HVAC, industrial, and other systems.
• Effectively reduces water hammer pressure, provides excellent sealing performance, and closes without noise.
• The design incorporating flow guides within the flow-type water channel ensures minimal pressure loss.
• Installed at the pump outlet, it can rapidly close before backflow occurs, preventing water hammer, water impact noise, and destructive shock waves. This achieves the purpose of preventing backflow and protecting equipment.
