Pneumatic eccentric butterfly valve

气动偏心蝶阀Adopting a three-dimensional eccentric metal sealing structure, the sealing form is metal to metal sealing, with interchangeable metal sealing rings for metal sealing, and stainless steel plates and composite graphite sealing rings for metal sealing. So it still has stable sealing performance under high temperature and high pressure conditions. The special sealing system of this valve ensures high sealing performance in various temperature ranges from ultra-low temperature to ultra-high temperature
