Watts double check valve assembly.
Specifications:
- Part Number: 909 Series
- Pipe Size: 3"
- Check Valve: 175 PSI Max
- Condition: New
Series 909RPDA reduced pressure detector assembly backflow preventers are designed to prevent the reverse flow of fire protection system substances from being pumped or siphoned into the potable water supply. The 909RPDA incorporates a meter to detect ground leaks and unauthorized illegal taps, greatly reducing annual water expenses. It consists of a coated cast iron body with stainless steel trim, cast iron gate valves, a pressure-differential relief valve, shutoff valves, and bronze ball-type test cocks. These large diameter backflow preventers provide maximum flow at low pressure drop utilizing the air-in/water-out design principle for protection during emergency combined backsiphonage and backpressure conditions. Maximum working pressure is 175 psi (12.06 bar).
Series 909RPDA is also available with SentryPlus Alertā¢ technology to detect excessive relief valve discharge that is likely to cause flooding and issue a multichannel alert (e-mail, text, and voice notifications), helping selected personnel take corrective action quickly and potentially avoid exorbitant repair and recovery costs.
For 909RPDA models currently in the field, upgrade kits are available to retrofit installations with the SentryPlus Alert system.
The coating on this backflow assembly uses ArmorTekā¢ technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate. ArmorTek advanced coating system is made of an anti-corrosion primer, a microbial inhibitor to limit MIC, and a protective epoxy-polyester topcoat.
