Running In And Pulling Out Devices For Back-Pressure Valves


The running in and pulling out device for backpressure valves is delivered together with all accessories necessary for well shutting-off jobs, fracturing and acidization.

The running in and pulling out devices allow the displacement of master valves, after the mounting of back-pressure valves.

The technology of well shutting-off by setting a back-pressure valve or a plug in the tubing hanger avoids well killing with drilling mud, this offering considerable economical and time advantages.

The back-pressure valves and plugs are designed to withstand the working pressure of the X-mas trees in which they are mounted.
The size ratings of the back-pressure valves and plugs are according to API sizes of the tubing string.
