HH44X/T/H micro resistance slow closing check valve

Working principle and purpose of the product:

HH44X, HH44T, and HH44H micro resistance slow closing check valves are used in water supply and drainage pipelines. They are installed at the outlet of the water pump to prevent media backflow and eliminate destructive water hammer, and can effectively reduce the pressure of valve closure water hammer, ensuring the safe operation of the pipeline network.

Suitable for installing pump outlets in industrial, agricultural, urban, high-rise residential and other water supply and drainage systems, to prevent media backflow, eliminate water hammer, and protect the safe operation of pumps and pipelines.

Product structure characteristics:

1. Equipped with a counterweight device. When the valve disc is rotated, the resistance to water flow is small, and the opening force is only one-fifth of the original rotating type, making it an energy-saving product.

2. The rear stroke of the valve disc closure is equipped with a damping device, and the damping time is adjustable to prevent the generation of destructive water hammer.

3. The valve disc has good sealing effect, vibration reduction, wear resistance, and long service life.

4. Smooth operation and low noise.
