The W-M Twin Plate Check Valve

The W-M Twin-Plate Check Valve is designed for use in drinking water, sewage, and fire protection systems as well as irrigation
and back-flow control systems. The valve is of simple, effective and durable design. The valve features a very compact wafer
style body of ductile iron construction. The disc can be supplied in aluminum bronze or 316 stainless steel. An o-ring forms
the seal between the body and disc allowing the valve to be rated to 16 bar.
