Product Description

HH44X Slightly resisted slowly closed check valve
Purpose
This valve is mounted on the pump outlet of the water supply and drainage system in industrial,agricultural,city,building etc.trades and used to prevent the medium from backflow, eliminate water hammer and ensure both pump and pipeline to work safely.
Features
With a balancing hammer set, there is a small resistance with the disc at swinging to the water-flow and the force to open the valve comes as only 1/5 that of the original swing type.
There is a damper set on the rest travel section of the disc after being closed and the damping time can be adjusted to prevent destructing water hammer from being produced.
A good tightness with the disc, reducing vibration, wearable and long durable.
Steady work, low noise.
