Introduction All the oilfield Valves used in the wellhead equipment is designed and manufactured as per API 6A, and different valves in various size will meet the customers’ requirements. Including below oilfield valve: *Gate vavle The Slab Gate valve Non-Rising stem type is available in Temperature class L,P,R,S,T, and U specified in API6A. High temperature is also available as per requested. Pressure rating from 2000psi to 15000psi, Material Class From AA to HH, Product specification Levels from PSL1 to PSL4. and Performance requirements PR1 to PR2. Specification for API 6A Gate valve Size 1 13-/16", 2 1/16", 2 9/16", 3 1/8", 3 1/16", 4 1/16", Working pressure 5000psi,10000psi, 15000psi Body Material Low alloy steel or stainless steel Cast Boy For 2000-5000psi working pressure Forged body For 10000-15000psi Seals Metal to metal *Plug valve The plug valve is a necessary part that is utilized on the high pressure manifold for the cementing and fracturing operations in oil field and also suitable to control over the similar high pressure fluid. Featuring the compact structure, easy maintenance, small torque, rapid opening and easy operation, the plug valve is ideal for the cementing and fracuring manifolds. Working Principles and character The plug valve consists of the valve body, plug cap, plug and etc. The plug valve is available with the union 1502 inlet and outlet preparations (also can be upon customer request). The side segments and the valve are the concentric circles The rubber was inlay in the external face of the side segments to seal the gap between the body and the side segments, The sealing between the side segments and cylinder plug is metal-to-metal. Match between these two parts is high-precision, and the sealing is stably. *Adjustable Choke Valve The needle and core are made of hard alloy. The valve is wearing, washing resistant and reliable. The external sleeve choke valve has low switch torque, realizing throttling and shutting fluid. Needle type and external sleeve type choke valves are available for Christ *Mud Valve The valve is applicable to mud circulating pipeline. Right/left thread is adopted in rotating bushing to improve switch efficiency. Various end connections are available, including flange, thread, union and welding. Standard: API 6A Specification level: PSL1 Performance level: PR1 Material level: AA, BB, CC, DD, EE, FF Temperature level: LU
