A damped check valve having multi-pressure operation is provided. The check valve includes a liner with a poppet movable within the liner. The liner defines a flow passage aligned along a longitudinal axis defined by the liner. A biasing element is operably coupled between the poppet and the liner to bias a first flow face of the poppet against an annular seat. The first flow face is configured such that a first fluid pressure is required to move the poppet from the closed position to an open position wherein the poppet is unseated from the annular seat and a second fluid pressure is required to hold the poppet in the open position, the second pressure being less than the first pressure. There is a sufficient diametrical clearance between the poppet and the liner which allows for flow control at pressures which are less than the initial opening pressure.

Flow control valves may be positioned downstream of water meters to increase pressure and compress entrained water vapour passing through the meters. However, turbulence within such valves can cause the valve's head to move radially, bending a shaft within the valve which may break. Accordingly, there is provided a flow control valve comprising: a housing having a flow passage; a valve seat defined within the flow passage; a valve head moveable to a closed position to engage the valve seat and seal the flow passage; a shaft secured to the valve head; a support slidingly mounting the shaft within the housing; a spring biasing the valve head to the closed position and configured to maintain the valve head in the closed position until a predetermined pressure is applied; and a guide assembly extending along at least a portion of the flow passage to constrain radial movement of the valve head.

A charge valve assembly for an air conditioning system includes a valve housing having a first end, a second end, and an inner surface defining a cavity. A valve core assembly is received in the cavity of the valve housing through the second end of the valve housing. The valve core assembly has a first end, a second end, a flow channel extending from the first end of the valve core assembly to the second end of the valve core assembly, an inner sealing surface, and a pin slideably received in the flow channel between an open position and a closed position. The pin has a primary seal selectively engaging the inner sealing surface of the valve core assembly and closing the flow channel at the second end of the valve core assembly when in the closed position. The pin biases towards the first end of the valve housing.

A one way valve cartridge for a flow assembly includes a housing having an axial aperture formed therein. A leading ring is coupled to the housing. A piston is disposed in the housing and is in sliding relationship with the leading ring. The piston is configured to reciprocate between a closed position to seal the axial aperture and an open position to permit a flow of fluid through the axial aperture. A spring urges the piston into the closed position to seal with the housing.

A valve guide for a coupling including a circular, longitudinally extending portion, including a substantially circular channel extending therethrough; a ring portion; a plurality of ports radially disposed around a centerline of the valve guide; and one of more collar supports disposed radially about the circular, longitudinally extending portion. The valve guide comprises a unitary one-piece component. A male portion for a coupling that includes a valve guide with integral assembly support and a method for assembling a coupling assembly are also disclosed.

A pressure relief valve includes a housing, a poppet, and a spring. The housing includes an internal bore defined along a longitudinal axis of the housing and extending from an upper portion to a lower portion. A ledge or seat is defined within the bore. At least one lower portion hole is defined from an outer surface of the lower portion and into the bore. At least one upper portion hole is defined from an outer surface of the upper portion and into the bore. The poppet is slidably engaged within the internal bore. The poppet includes a head, a shaft, and an internal channel that runs longitudinally through the entire poppet. The head includes a shoulder. The spring is disposed within the bore at the upper portion of the housing and biases the poppet downwards so that the shoulder abuts the ledge or seat.
