High Pressure Part Rotary Plug Valve with Strong Precision

PLug Valve
Description
Plug Valve is an important high pressure part for well service to allow and stop flow by plug rotation.
plug valves are made from premium alloy steel, with special coating and heat treating process which greatly improves sealing capabilities, anti-abrasive and corrosive resistance.
5 basic types (manual, hydraulic, electric, handwheel and manual & hydraulic actuators) are available to meet various needs applicable to different services.
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 fracturing manifolds.
Working Principles and FeaturesThe 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 available upon customer request). The cylinder body inner wall and side segments work together with the rubber seal segments to provide sealing.The metal-to-metal sealing is available between the side segments and cylinder plug, featuring high precision and reliability.Note: the valve can be easily opened or closed even under the 10000psi high pressure.
Operating InstructionsFill the clearance between the body and side segments with grease prior to use.Perform hydrostatic tests prior to use to make sure that no leakage occurs.Check if the valve position is in line with the mark and rotate the plug cap 90 degree to see if the plug valve can be operated freely.
MaintenanceThe regular and timely maintenance can prolong the service life of the plug valve.Clean and grease the plug valve timely after it stops working.All seals shall be checked for damage at specified intervals and the damaged shall be replaced immediately.If the sealing between the plug and side segments fails, they shall be disassembled and checked timely. If the sealing surface is found to be defective, it shall be polished.ItemComponentQtyMaterialRemark1Body141302Packing210103O-Ring2NBR4Side Segment24105Plug141306Seal Segment2Rubber7Seal Segment24108O-Ring1NBR9Body Cap1413010O-Ring1NBR11Plug Cap1WCB12Lock Nut1514013Grease Fitting1Assy.14Locating Pin1104515Detachable Nut1104516Retainer Segment3514017Retainer Ring1156618Seal Ring1Rubber19Stop Pin1410
