Product description
This eccentric pneumatic butterfly valves have a "U" type stainless steel seal ring, this seal ring and the tripple eccentric polishing disc contact with each other to solve the problem that the seal surface is still in the sliding contact friction when the traditional eccentric butterfly valve opened and closed from 0 ° to 10 ° in a twinkle, which realizes the seal surface separating when the disc opened in a twinkle and seal recovery when the disc closed.
