What is the structure of a two-way hard-sealing butterfly valve?
Thread Content
Xiaobai asks: For a double-sealed butterfly valve with direct contact between components, what type of sealing ring is used for the butterfly valve? Are there any screenshots of the sealing surfaces? I want to learn*learn*.
Regarding two-way hard-sealed butterfly valves, their main structural features can be summarized as follows: they employ a spherical sealing structure with a hard seal similar to that of ball valves, have a compact flange layout typical of butterfly valves, possess the wear-resistant properties of hard-sealed ball valves, and at the same time feature a compact installation length typical of butterfly valves. It is possible to manufacture ball valves with a large diameter of up to 2400. However, at such a diameter, the volume, weight, and operating torque of the valve become too high; details can be discussed by contacting 15333832617 :)
