With a working pressure of 150 psi and temperatures up to 110 degrees Fahrenheit, the double check backflow preventer from A.R.I. is designed to provide excellent defense and resilience against back flow caused by opposite or negative pressure. This state-of-the-art device consists of two independently acting, spring-loaded check valves. It also has two resilient seated shut-off valves and four test cocks which complete the assembly.
Each check valve is expressly designed to maintain a minimum of 1 PSI across the backflow assembly during standard operation. If at any time the pressure downstream of the device increases above the supply pressure, both check valves will close to thwart any backflow from happening.
The three quarter inch (3/4 inch) double check backflow preventer is recommended in low hazard applications where the degree of pollution doesn?t impose the use of a reduce pressure device in high hazard applications. This trustworthy and simply maintained assembly does not require specialized equipment as its two, easily replaceable, spring check valves are situated in independent capsules. This modular design, and nylon composite body, makes it the backflow of tomorrow.
