DIAPHRAGM VALVE SEAT

摘要

A thermally and chemically inert valve seat (20) is provided. The valve seat (20) includes a sharp edge (55) located on the periphery of the valve seat body, wherein the edge (55) digs into a surface within the valve body (25) to secure the valve seat (20). The valve seat (20) may be case hardened to provide additional strength and sealing ability. The inner diameter of the valve seat (20) may be flush against the valve fluid passageway, thereby decreasing the contact area between the diaphragm and the valve seat.
