Product Description
Triple-offset Butterfly Valves are torque-seated valves where bubble-tight sealing is achieved when the laminar seal flexes and generates a compressive force all around the hard-faced body seat. The laminar seal of Triple-offset Butterfly Valves are designed to be replaceable at site.These valves are used mostly in applications where a tight bubble shut-off is required, a high temperature is expected, or hard sealing surfaces are required with zero leakage (soft seat) or rated leakage (metal seat).
