We supply standard 6A Gate Valves including FC Style Gate Valves, FLS-R Valves, Hydraulic Valves, Expanding vales.
- 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
1. Gate is fission expanding structure
2. Realizing low torque or low wear during the switch
3. Between bonnet and body are adopt metal to metal seal
