• It prevent the reverse flow of hot or cold polluted water from entering into the potable water supply It consists of a brass body with stainless steel internal parts, integral strainer and two durable, tight-sealing, rubber check valves For continuous pressure, non-health hazard applications in smaller supply lines It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing A secondary check valve utilizes a rubber disc to metal seating In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system True line sized construction allows the check modules to open further allowing dirt and debris to pass more freely reducing check fouling Maximum flow at low pressure drop Furnished with union connections to facilitate removal and replacement for maintenance Compact for economy combined with performance Design simplicity for easy maintenance Can be installed vertically or horizontally

This 3/4 inch dual check valve backflow preventer with atmospheric vent prevents the reverse flow of hot or cold polluted water from entering into the potable water supply. This valve is designed for continuous pressure non-health hazard applications in smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines. It consists of a brass body with stainless steel internal parts, integral strainer, two durable tight seating rubber check valves, and NPT female inlet and outlet connections.
