Downhole Testing Mechanical Tester Valve 5 Inch x 10000 psi Alloy Steel with 140 MPa Working Pressure and 2991 mm Length
Professional mechanical tester valve designed for drill stem testing operations in oil and gas applications. This 5-inch valve with 10,000 psi rating controls well flow through precise ball valve operation.
The mechanical tester valve opens and closes well flow by lifting and lowering drill pipe or tubing. When running in hole, the valve remains closed. At predetermined depth, the J-slot mandrel moves up and down via workstring weight, allowing the transposition lug to rotate freely along the index groove travel path. Each lift or set down of the workstring changes the J-slot mandrel position, enabling repeated ball valve opening and closing cycles as required.
