Triple Offset Butterfly Valves are suitable for both shut off and throttling service. The triple offset design incorporates torques in seating for tight shutoff or control evenin the roughest applications. Industries where the triple offset butterfly valves are widely used include power, refining, petrochemical, chemical and pulp & paper.
A butterfly valve is a valveundefinedundefined through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is alwundefinedundefinedocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to tundefinedowest pressure rating. The high performance butterfly valve, used in slightly higher-pressure systems, features a slight offset in the way the disc is positioned, which increases the valve's sealing a
