High performance butterfly valves are designed to be double offset. When operating, the offset disc produces a cam-like action, pulling and pushing the disc to and from the seat. This cam-like action reduces seat wear and operating torque and provides bi-directional, zero leakage shutoff throughout the full pressure range. High performance BFV are available in soft, metal & fire-safe seat designs and used in systems that need higher pressure flow control.
