High Pressure Flange lifting type hard seal plug structural features
1, reasonable structure, reliable sealing, excellent performance, attractive appearance;
2, the Iso 9001 Ansi Lifting Type Plug valve opening and closing process is in a state from the sealing surface will not cause wear of the sealing surfaces.
3, to enhance the two-way flow flange type hard seal plug, installation more convenient.
4, part material and flange size according to the actual working conditions or user request for reasonable matching, to meet various project needs.
The valve opening and closing works
Plug the opening and closing process: Open the valve, first turning the handwheel, make plug rising to the surface from the seal, then rotate the handle 90 °, so that the valve plug channels and communication channels to reach the open goal. And the valve closing process is to rotate the handle 90 °, so that the vertical channel and the channel stopper valve, and then rotate the hand wheel so that the stopper down to seal.
