API-6A 2000psi ~ 15000psi Various series specifications for high pressure valves
API-6D    Heavy Caliber Ball Valves Line Pipe Valve

1.Flat valve
The facing of valve plate and valve seat spray / surfacing cemented carbide.The seal between the valve seat and the valve plate, the seal between the valve body and the valve cover, and the sealing of the valve stem are all metal seals.



2.Expansion valve
Plastic /V seals are kept clean and reduce maintenance costs.The design of parallel expansion valve plate ensures reliable sealing.Even under full pressure, double needle roller thrust bearings ensure light operation.



3.Choke Valve
Material comply with API 6A standard and NACE standard.Throttling nozzle and valve seat are made of cemented carbide / ceramic. It has anti abrasion, anti erosion and reliable performance.
