Introduction to the sleeve regulating pneumatic valve

the sleeve regulating pneumatic valve has the unbalanced force is small, allows the characteristics of differential pressure big, under the market users, more information about the sleeve pneumatic valve adjustment, look small make up the following introduction:
sleeve to adjust the sleeve of pneumatic valve and pneumatic disc for clearance fit, there are multiple throttling Windows open on the sleeve, the shape of the window made adjust the flow characteristic of pneumatic valve, the area of the window size effect on regulating pneumatic valve flow coefficient Cv.
pneumatic seat is since no thread card into the structure, pneumatic valve seat sealing surface of cone and pneumatic cone sealing faces on cooperate form to cut off the seal, ensure that pressure in the pneumatic pneumatic valve seat valve pneumatic valve tightly shut off. Pneumatic valve seat diameter size affect the adjustment of the pneumatic valve flow coefficient Cv.
pneumatic disc on parallel to the axial symmetry distribution balance hole, the end of the pneumatic valve disc up and down chamber connected, so that pneumatic valve within the medium role in the upward force of a pneumatic valve shaft most cancel each other out, medium in pneumatic valve stem of unbalanced force is very small.
on the sleeve, there is a balance of ptfe seal seat when pneumatic disc fitted, balancing on pneumatic valve sealing surface pressure on the sleeve formed on the balance of ptfe seal seat tightly cut, to ensure that the chamber on the medium can't enter the balance room. As it moves, a pneumatic valve disc up and down on the sleeve of throttling channel area of the window change, thus realize regulating the function of the medium flow rate and pressure in the pipeline, etc.
