Lug Style Check Valves

Lug style check valves, or lug type 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. Marshall J. Brown carries lug style check valves that range from 2-10 inches in size. You can view specifications for our wafer check valves here.
