Watts 0111523 Details
This Watts 757-NRS 3" double check valve backflow preventer assembly is designed to prevent backsiphonage of polluted water into a potable water supply. It's ideal for protection at cross-connections identified as non-health hazards or from other contaminants found at service line entrances. This valve has 3" flanged joint inlet and outlet connections, and it features a type 304 stainless steel body and sleeve with bronze body nickel-plated test cocks. Plus, it's 70% lighter than traditional designs. Thanks to its compact, modular design with a single-access sleeve, this unit facilitates easy installation and maintenance.
The patented tri-link checks ensure low pressure loss and are serviceable without the need for special tools. This assembly also has non-rising stem resilient (NRS) seated gate valves. It comes complete with a replaceable check disc rubber, groove fittings for integral pipeline adjustment, two independently operated check valves, two drip-tight shutoff valves, and four ball valve type test cocks. It has a temperature range of 33 to 140 degrees Fahrenheit and a maximum working pressure of 175 PSI.
