Products Specification about Water Check Valve Backflow Preventer

HS41X -A Antifouling partition valve  Backflow Preventer, Check Valve QT450

HS41X-A anti-fouling partition valve consists of two separated check valves and a hydraulic drive to the drain valve. The check valve body is equipped with a filter screen. Because of the partial head loss of the check valve, the pressure in the middle chamber is always lower than that in the intake. This differential pressure drives the drain valve to be closed and the pipeline to supply water normally. When the pressure is abnormal (that is, the outlet pressure is higher than the backbone chamber), even if the two check valves can not be reversed sealed, the drain valve can automatically open and empty the backflow water, and form an air partition to ensure the sanitation of the upstream water supply.

HS41X-A anti-fouling partition valve type A product structure has the characteristics of rationality, easy to use products, strong sealing performance, durability and beautiful appearance. HS41X-A anti-fouling partition valve is widely used in power, metallurgy, petroleum, chemical industry, gas, urban construction, paper making, textile, medicine, food, shipping, water supply and drainage, energy, drilling and other departments.
