Abstract

The valve consists of a housing (1) with a chamber (11) connecting inlet (2) and outlet (3) ducts, containing a seat (3) for a valve plate (4) which moves between closed and open positions. The housing is connected to a cap (6) with its interior separated from the chamber by a membrane (15) which has a rod (41) connected to the valve. The outer edge of the membrane is in contact with the periphery of a guide (64), with both fixed between the housing and cap, and its inner edge is fixed between a thrust surface on the rod and a second guide (65,66), with both guides having rounded surfaces to support the membrane. The plate valve and seat are made from a metal such as a cobalt alloy.
