Abstract

A fluid flow control valve is disclosed in which the movable element of the valve is in the form of a spool mounted in a casing by means of two rolling diaphragms. The spool is hollow and a fixed cross-bar passes through it. In one form, the spool carries a valve closure member and the outlet is in the centre of the cross-bar. In another form, the cross-bar carries the closure member and the valve outlet is an axial bore leading from the hollow interior of the spool. The valve inlet leads to the annular chamber defined between the casing, the spool and the diaphragms. The areas of the end walls of the annular chamber are different to one another and are chosen so that an inlet pressure derived force acts on the spool to reduce the out of balance forces which act thereon due to the provision of the outlet. A modification which acts as a flushing valve is also disclosed.
