Lugged High Performance Butterfly Valve 2" - 48" Stainless Steel Triple Offset

Lug Type High Performance Butterfly Valve Stainless Steel Triple Offset

High Performance Butterfly Valves have either resilient disc or seat seal, which is replaceable. Compare to the rubber lined butterfly valves, the offset design of the high performance butterfly valve increases the valve's sealing ability, decreases its tendency to wear and lengthen its service life.

Lug type butterfly 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 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.
A lug type butterfly valve used in dead-end service generally has a reduced pressure rating. For example, a lug type butterfly valve mounted between two flanges has a 150 psi pressure rating. The same valve mounted with one flange, in dead-end service, has a 75 psi rating.
