Ductile Iron Flanged Anti Fouling Isolation Valve With Strainer
Product introduction:
The HS41XA filter and anti fouling isolation valve consists of two separated check valves and a hydraulic transmission to the drain valve. The first check valve body is equipped with a filter screen. Due to the local head loss of the check valve, the pressure in the middle chamber is always lower than the pressure at the inlet. This pressure difference drives the drain valve to be closed and the pipeline is supplying water normally. When the pressure is abnormal (i.e. the outlet pressure is higher than the middle chamber), even if both check valves cannot seal in reverse, the safety drain valve can automatically open to empty the backflow water and form an air partition, ensuring the hygiene and safety of the upstream water supply.
