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.

Abstract: A control valve is provided, comprising a valve body having an inlet port extending along an inlet axis, first and second outlet ports extending along outlet axes substantially parallel to a single reference axis and substantially perpendicular to the inlet axis, first and second sealing ports associated, respectively, with the first and second outlet ports and each disposed in a fluid path between the inlet port and its respective outlet port, and first and second sealing members configured for independently and selectively opening and closing the first and second sealing ports, respectively. Each of the sealing ports extends along a sealing axis extending transverse to a plane being parallel to its respective outlet axis and the inlet axis, and forms, between a downstream end thereof and an upstream end of the inlet axis, an obtuse angle greater than 90°.

Abstract: Provided is a valve including a housing fitted with a valve coupling port being in flow communication with a gas inlet valve component and an independent gas discharge valve component. The gas inlet valve component includes a normally closed valve inlet port and an outlet barrier configured for spontaneous opening to thereby facilitate only ingress of ambient gas into the housing upon pressure drop at the valve coupling port The gas discharge valve component including a valve discharge port and a displaceable float member to thereby facilitate spontaneous egress of substantially only gas from the housing and remain closed upon presence of liquid within the housing.
