صمام FC
● Full-bore design, effectively eliminate the pressure drop and eddy current, slow flow of solid
particles in the valve.
● The unique sealing, make the switch torque greatly reduced
● Between bonnet & body and gate & seat are adopt metal to metal seal
● Between gate and seat are adopt metal to metal seal, Surface spraying (heap) welding hard
alloy , has good abrasion resistance, corrosion resistance.
● Seat ring is fixed with plate, keep well steady
● Stem has back seal structure so as to replace seal ring of stem with pressure
● There is seal grease injection valve on bonnet side so as to repair seal grease , and provided
seal and lubricate performance of gate and seat
● It is match with all kind of pneumatic (hydraulic) actuator as customer’s requirements
Expanding gate valve
● Gate is fission expanding structure
● Realizing low torque or low wear during switch
