JFC valve

• 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
