Product Name: Bso Gate Valves/ API Standard 6A Ball Screw Gate Valve Model NO.: API 6A Type: Composite Structure: Vertical Installation Position: Overwater Well Type: Chassis Well Connection Form: Flange Applicable Medium: Mud, Water, Natural Gas, Crude Oil Drilling Program: Two Stage Trademark: WS Transport Package: Plywood Case Specification: 7-1/16" Origin: China HS Code: 848190 Product Description Frac Valves are Ball Screw Operated (BSO). Frac valves - ball screw gate valves is a typeof large bore gate high pressure valve which were improved from Cameron FLSR gate valve, it's the main component of frac tree, the frac valve is often used on the top of the wellhead on high pressure oil well, can do the frac job for isolating the fluid from the well. They are high-pressure isolation valves installed on the top of the wellbore on a wellhead platform.Frac Valves/BSO Gate Valves feature either flanged end connections or studded ones. These Valves can be operated with help of actuators with variable drive motors or can be operated manually. Frac Valves are usually made for large bore applications. These types valves have bi-directional design which allows flexibility in the direction of flow of hydrocarbon stream. Frac valves are used by specialized well control organizations and are the preferred choice of valves by organizations that perform drilling on shale plays.Specification:Bore Size:3-1/16", 4-1/16", 5-1/8", 7-1/16", 9"Rated Working Pressure:10000PSI, 15000PSIOperation:Manual, Hydraulic, Ball Screw Operator (BSO)End Connections:Flanged, Studded OutletMaterial Grade:AA, BB, CC, DD, EE, FFTemp Class:L-U, P-UProduct Specification Level:PSL1, PSL2, PSL3, PSL3G, PSL4Performance Requirement:PR1, PR2Standard Carried:API Spec 6A, NACE-MR0175Application:Frac Tree, Oilfield Fracturing Operations
