Abstract

Official abstract text for this publication.

A fluid control valve includes a pressing member, a diaphragm member, and a valve seat. The pressing member presses and deforms the diaphragm member into contact with the valve seat. The valve seat includes a first annular valve seat made of fluorine resin and a second annular valve seat made of heat-resistant resin, which are arranged concentrically adjacent to each other. The heat-resistant resin has a higher deflection temperature under load at 1.82 MPa than the fluorine resin, measured according to ASTM D-648.
