Stop valve:
1) The stop valve is an adjustment component in the pipeline system that pushes the valve disc to move vertically along the center line of the valve seat through the rotation of the handwheel to cut off the flow of the control medium. When working, the friction between the disc and the sealing surface of the valve body is small, the opening and closing torque is small, and there is only one sealing surface for easy maintenance.
2) The globe valve has threaded and flanged connections, and the valve body and bonnet adopt the thermostatic hot forging and tempering process, which greatly improves the mechanical performance and safety factor of the valve. The valve pressure test is carried out in strict accordance with the GB/T13927-1992 "General Valve Pressure Test" standard, and 100% of the tests are qualified before leaving the factory.
3) Valve installation must be carried out by professionals with relevant qualifications, and the deviation of the different axial degrees of the pipelines at both ends should not be too large, otherwise excessive pipeline installation stress will be generated and the valve will be damaged. Wrench the hexagonal or octagonal part on the same side of the thread when installing and tightening, and should not wrench the hexagonal or octagonal part on the other end of the valve to avoid deformation of the valve.
