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 steadly
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
