Product Details
Watts 957 series reduced pressure zone assemblies began production in 2000 under the Hunter name, with Watts acquiring the rights in 2002 and continuing manufacturing. Available in sizes 2 1/2 - 10", these assemblies are constructed of stainless steel, featuring a lightweight design and short lay lengths that have made them a top seller. The series offers various configurations with multiple valve options, allowing access to the check assemblies via a stainless steel sleeve that slides open. For sizes 2 1/2 - 6", the #3 test cock must be unthreaded before sliding the cover, while the 8 - 10" sizes use two Victaulic clamps to secure the stainless sleeve. The 957 series incorporates two self-contained cam checks utilizing a tri-link check mechanism, and a piston/diaphragm style relief valve with an external sensing line hose. Service requires no special tools.
