Abstract

A valve assembly (10) is described comprising a valve body (12) and a manifold body (14) that overlays the valve body (12). In its simplest form,a pair of ports (22, 24) opens to the upper surface of the valve body (12) adjacent one another for ingress and egress of a fluid. The paired openings define a valve seat area (26) on the upper surface of the valve body (12). A flexible membrane (28) overlays the valve seat area (26) and is actuated by air pressure for movement between a closed position sealing the port openings (22, 24) and an open position allowing fluid communication between the port opening pair (22, 24). Conventional valves such as solenoid valves are provided to control the flow of air to the membrane sheet (28). Ancillary equipment such as the solenoid valves, is isolated from the fluids flowing through the valve body (12) to reduce maintenance and increase the useful life of the ancillary equipment.
