API 6A Plug Valve
Oil well Plug valve for wellhead
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.
Note: the valve can be easily opened or closed even under the 10000psi high pressure.
Operating Instructions
Fill the grease 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 whether the valve position is in match with the mark and rotate the plug cap 90 degree to see if the plug valve can be operated freely.
Maintenance
The regular and timely maintenance can prolong the service
