API 6A Gate Valves for Oilfield wellhead

Main Technical Features

Standard API6A Gate Valves including FC Style Gate Valves, FLS-R Valves, Hydraulic Valves,

Expanding vales is available.

FC 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 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
