【Product Introduction】:

High Performance Double eccentric butterfly valve,in addition to the conventional valve had to adapt to the working condition of the medium,according to different medium,chose different structure material and special processing,can aslo be used for cryogenic、vapor、chlorine gas、oxygen、high vacuum、corrosion and other special conditons. Zhengfeng vlave Design standard :API 609, DIN2559, EN593, JIS, GOST and so on.


【Seat Tightness】:

1. When pressure is on the insert side,pressure is applied under the seat lip.This further amplifies the sealing force between the disc and the seat.

2. When pressure is on the non-insert side,the disc moves into the seat.Due to the spherical profile of the disc,the more the disc moves into the seat,the tighter the shut-off.Excess movement of the seat is limited by the flexible lip which contacts the bottom of the groove in the insert ring.
