Resilient Seated Butterfly Valve

Resilient Seated Butterfly Valve has rubber seat, unique shape, compact structure, high-strength disc using frame structure. It has bidirectional sealing function for installation without the interference of the medium flow direction. The surface is coated with epoxy resin, which could prevent rust effectively, a wide choice of seat material can be used in different medium, such as water, oil and gas.
