Applicable Standards



Lug-Style Butterfly Valve


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. 

In the pharmaceutical, chemical and food industry a butterfly valve is used to interrupt product flow ( solid, liquid, gas ) within the process.
