Abstract
A fluid control valve is provided, comprising a valve body configured with an inlet port extending into an inlet chamber, and an outlet port extending from an outlet chamber. The inlet and outlet chambers are partitioned by a sealing bridge. A control chamber accommodates a flexible sealing diaphragm deformable between a sealing position in which it sealingly bears over the sealing bridge and seals a fluid flow path extending between the inlet and outlet chambers, and an open position in which fluid flow along the flow path is enabled. An inlet path along the fluid flow path is longer than an outlet path therealong. An inlet radii of the sealing diaphragm is longer than an outlet radii of the sealing diaphragm.
