A.R.I. 2" DC-501 Nylon Composite - Double Check Assembly

If you are responsible for a backflow preventer at your home or business, you know the problems that can be caused by harsh water, high lead levels and even theft. Luckily a new generation of backflow preventers has come to the market, the DC-501 series from A.R.I. This one-of-a-kind 2? double check backflow preventer is suggested where the degree of potential pollution doesn?t require the use of a reduce pressure backflow apparatus.

The 2" DC-501 from A.R.I. is a novel solution; made of two independent, spring-loaded check valves, it uses four test cocks and two resilient seated shut-off valves to ensure backflow prevention.

Our easily serviced and dependable backflow preventer doesn?t require specialized equipment, because its two, replaceable, spring check valves sit inside independent, modular capsules. With a polymer composite body thieves have no desire to steal it as it does not contain brass or copper.

Both check valves are engineered to maintain a minimum of 1 PSI throughout the backflow preventer during standard use. If the pressure exiting the device ever rises above the incoming pressure, each check valve will seal to prevent backflow from occurring. It has a working pressure of 150 psi and can withstand temperatures up to 110 degrees. Our double check backflow prevention device is meant to provide exceptional protection against undesired backflow.
