ABSTRACT:
A valve body (12) has an inlet opening (22) and an outlet opening (24) interconnected by a fluid passageway (28, 30) having a flow aperture (34). The valve comprises a diaphragm (14) (typically of the duckbill type) that is located across the flow aperture (34) and has slits in a collapsible aperture (39). This prevents backflow from the outlet to the inlet. The valve has an actuator (16) in the form of a plunger for influencing the fluid flow. Also disclosed is a pressure release valve whereby a high pressure on the outlet side can partially collapse the aperture (39) to temporality vent fluid from the high pressure outlet side.
