Gate Valve

We supply standard 6A Gate Valves including FC Style Gate Valves, FLS-R Valves, Hydraulic Valves, Expanding vales.

FC valve

Full-bore design, effectively eliminates 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 a back seal structure so as to replace the seal ring of the 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 matched 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 the switch
Between bonnet and body are adopt metal to metal seal
