1" Backflow Preventer Valves

Our selection of 1-inch backflow preventer valves includes models from the best-known manufacturers in the industry, such as Watts 1 backflow preventers, Febco 1 double check valves, Wilkins 1-inch backflow preventers and the Watts 1-inch RPZ backflow preventers. These Series 009 1" Watts reduced pressure zone assemblies have a bronze body construction, two check valves placed inline with a central relief valve, replaceable check-valve seats and screwdriver-slotted ball-valve test cocks. The Series 009 devices are perfect for protecting against health hazards possible with unprotected cross connections. They may be ideally installed as containment valves where service lines make their entry. Top entry to internals promotes ease of maintenance, and no special tools are required. Large body channels promote low-pressure drop.
