The present application concerns a valve, and particularly position indicating assembly for use therewith. The position indicating assembly comprises a first end engageable with a valve member of the valve, an opposite second end displaceable with respect to a body of the valve in response to displacement of the first end, and an elongate bendable portion, extending between the first end and the second end, configured, upon movement of the valve member, to transmit forces operating along the elongate bendable portion, at least from said first end to said second end, so as to displace said second end, the elongate bendable portion being further configured for damping forces operating transversely thereto by reversibly bending.

Hydraulically operated valve and systems for use therewith

A PRV is provided, comprising an inlet, an outlet, and a pressure regulating system therebetween to maintain a set pressure at the outlet. The PRV further comprises a selection system configured to select between the two working pressures based on the pressure of the fluid at the inlet of the PRV, and to direct the pressure regulating system to maintain the set pressure at the outlet at the selected working pressure. The selection system comprises a pressure-motion transducer for directing the set pressure when in pressure communication with the inlet, and an auxiliary valve having an auxiliary inlet in pressure communication with the inlet and an auxiliary outlet in pressure communication with the pressure-motion transducer. The auxiliary valve is configured to establish pressure communication between its inlet and outlet when pressure in the inlet traverses a predetermined threshold.

Dual set-point pressure regulating system

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.
