3/4 IN Bronze Dual Check Valve Backflow Preventer with Immediate Atmospheric Vent, Less Union
This 3/4 inch non union 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.
Features
- Primary check valve has rubber disc seating against a mating rubber part to ensure tight closing
- Stainless steel internal parts for longevity
- Can be installed vertically or horizontally
- Line-sized construction enables check modules to open further, helping to reduce check fouling
