SLIDE FOR A SLIDE VALVE, AND METHOD FOR THE MANUFACTURE THEREOF

摘要

A slide for a slide valve consists of an injection-molded, glass fiber reinforced, mineral-filled thermoplastic material having a high thermal stability of shape, a compressive strength of not less than 110 MPa and a Rockwell hardness of not less than R-117. The only machined surfaces are ground peripheral surfaces forming the sealing surfaces of the several subdivisions of the slide, which have an intact homogeneous texture.
