1.FC gate valves are mostly used to all sorts of wellhead Christmas trees and manifolds, etc, with working pressure are 3000, 5000, 1000 and 15000 psi, inside nominal diameter 1-13/16” ,2-1/16” ,3-1/16”,4-1/16”, 5-1/8”, 7-1/16, satisfied with all requirements of relative oilfield products.
2. Requirement for material, mechanical property and pressure test conform to API 6A specificat ion.
3. FC series gate valves have the outlet and seals. Entering the vlave from one end.,fluid push the seat toward the valve gates and make them integrate closely, then gain the seal.
4. For the two ends of the FC gate valves, any one end can be as inlet or outlet end.
