Designed for smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines to prevent backflow, this valve should be installed at referenced cross-connections vertically or horizontally.

This 3/4 inch dual check valve backflow preventer with atmospheric vent boasts a powerful function, preventing the reverse flow of hot or cold polluted water from entering the potable water supply.
