Wafer Check Valves
Wafer check valves provide silent, fast, non-slam operation and feature a special quick-closing action for added control and convenience. Wafer check valves are designed to fit between a set of flanges. Wafer check valves include an accurately machined disc that protects against momentum build-up and its valve-damaging effects.
Lug-Style Check Valves
Lug-style check valves provide superior manual control over any industrial pipeline and feature a variety of control-valve styles and sizes. Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.
