3、 Working principle of imported soft seal gate valve:

No cavity structure is adopted. Epoxy resin is sprayed on the inner and outer surface of the valve body and cover. Rubber is coated on the surface of the ram to eliminate the possibility of corrosion. Instead of packing, O-ring is used at the valve stem seal to make the seal more reliable. According to the need, the gate valve can be operated by operating rod, hand wheel, electric and pneumatic.
