Abstract

A valve comprising a housing defining a control space with an outlet port for fluid egress from the space and at least one inlet port for fluid ingress into the space control member is displaceable between an open state in which the outlet port is open and a closed state in which the outlet port is closed. The at least one inlet port of the at least one inlet port is formed at a wall portion of the housing at an upper wall portion, and a fluid draining port is formed at or adjacent a bottom end of the housing for draining fluid from the control space. The fluid draining port serves for preventing fluid ingress into the control space.
