Triple Offset Butterfly Valves
Triple Offset Butterfly Valves
Kent Triple Offset Butterfly Valve design offers rugged reliability and extremely easy maintenance in the field. These valves are bi-directional with advanced design features such as 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 to regulate the flow. A triple offset butterfly valve (TOV or TOBV) is often used in critical applications and is designed similar to a double offset butterfly valve. The third offset is the disc-seat contact axis. The seat surface takes a conical shape, which, coupled with the same shape at the ridge of the disc, results in minimal contact before full closure of the valve. A triple offset butterfly valve is more efficient and allows for less wear. Triple offset valves are often made with metal seats to create a bubble-tight shut-off. The metal seats allow butterfly valves to be used in higher temperature ranges.
