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.

Abstract
A gas purge valve (20) comprising a housing (22) configured with float chamber (40) extending between a fluid inlet port (36) and a fluid outlet port (38), the float chamber accommodating a float- activated valve assembly (50) axially displaceable within the float chamber. The valve assembly comprising at least a kinetic sealing component (54) being axially displaceable within the housing between at least a closed position sealingly engaging a sealing seat (48) of the fluid outlet port, and an open position in which it is disengaged from the sealing seat. The fluid inlet port is in flow communication with the float chamber through a fluid inlet path configured with a fluid flow regulator (100) configured with a fluid discharge flow path (102). The arrangement is such that the minimal diameter of the fluid discharge flow path is greater than the diameter of at least a lower portion of the valve assembly.
Provided is an automatic gas purge valve system including a normally closed gas discharge faucet configured for discharging gas at substantially high flow rates, and an automatic valve unit configured for selectively generating a flow pulse to displace the gas discharge faucet into its open position.

An automatic gas purge valve system ( 10 ) comprising a normally closed gas discharge faucet ( 100 ) configured for discharging gas at substantially high flow rates, and an automatic valve unit ( 46 ) configured for selectively generating a flow pulse to displace the gas discharge faucet into its open position.
A gas purge valve (114A-D) is provided within a fluid system, the valve being configured with one or more sensors (134B) each for sensing and generating one or more signals indicative of parameters associated with the valve. The fluid system further comprises a power source and a transmitting system for transmitting signals from the sensors to a remote control station (130).
A liquid purge valve comprising a housing for sealingly fitting at an uppermost end of a substantially vertical pipe, an outlet tube extending from the housing and projecting into the pipe, an outlet port fitted with a sealing boundary and sealable by a sealing member pivotally secured within the housing so as to pivotally displace between a closed and an open position, a biasing member biasing the sealing member into its open position, and a mass articulated to the sealing member and extending downwards into the pipe. The mass applies a force at an opposite direction of the biasing member such that the resultant force acting on the sealing member determines its position such that when water level rises within the pipe the sealing member displaces into the open position.
A gas purge valve (10) comprising a housing (14) formed with a fluid inlet (20) and a fluid outlet (24), said fluid outlet bounded by a kinetic valve seating (26), and a sealing assembly (30) comprising a float member (32) coaxially displaceable within the housing, and a sealing cap (40) coupled to said float member; the sealing cap being axially displaceable with respect to the float member between a first position in which it conjoins the float, and a second position in which it departs from the float; said sealing cap formed at an outside face thereof with a kinetic seal (48) fitted for sealing engagement of the kinetic valve seating, and an automatic valve aperture (44) formed in the sealing cap and bounded by an automatic valve seating (50); and an automatic sealing member (54) articulated at an upper end of the float member for sealing engagement of the automatic valve seating (50).
