Backflow Prevention


Valve Setters

Lead Free* Models Available


3 to 10 in. (80 to 250mm)


Series WVS Valve Setters are designed to augment the installation of the "N" series backflow prevention valves. They are available in three connection options: Flange x Flange, Mechanical Joint x Flange and Mechanical Joint x Mechanical Joint. Series WVS is constructed of fusion epoxy coated ductile iron. Integral ductile iron support between elbows transfers thrust downstream, thus eliminating thrust block requirements between elbows. Mechanical joint restraint devices may be used at the pipe connections, depending on local conditions.
