Triple Offset Butterfly Valve
Our Triple Offset Butterfly Valve design offers rugged reliability and extremely easy maintenance in the field. These valves are Bi-directional and with advanced design features of Triple eccentricity and unique elliptical seat geometry ensuring compressive sealing around the entire seat and a “tight”, bubble-free valve. These valves are well suited for operation in light vacuum to high pressure applications. The standard, non-rubbing, metal-to-metal sealing system is inherently fire safe by design. Triple offset butterfly valve can be used not only on-off but also regulating the flow. These valves are available in wafer, Lugged and Double flanged construction.
