Stainless Steel Metal Seated Butterfly Valve

It reduces the friction between disc and seat, and increases the valves service life. Disc and seat oblique cone design turns the compression seal into torque seal, achieves bi-directional seals. Metals and non-metallic compound seal ring combines the rigidity of the metal, the wear-resistance and flexibility of the resilient seat, ensures reliable seal and greater performance. And we offer the material test report and the manufacture conformance for each order. At last, the free sample is available if you need.
