Abstract
A seat carrier subassembly for a valve includes first and second ring components assembled over an O-ring seal, wherein a portion of the O-ring seal is exposed in an inner diameter gap between inner edge portions of the first and second ring components to define a seat seal.
Claims20
A valve assembly, comprising:
- a valve body including:
- a body housing defining a first end port, a second end port, and a central cavity extending from a bottom end of the body housing to a top end of the body housing;
- and
- a body plug assembled with the central cavity of the body housing and defining a flow path between the inlet port and the outlet port;
- a seat carrier subassembly disposed in the body housing and secured between an end face of the body plug and a counterbore in the central cavity, the seat carrier subassembly comprising first and second ring components assembled over an O-ring seal, wherein a portion of the O-ring seal is exposed in an inner diameter gap between inner edge portions of the first and second ring components to define a seat seal;
- and
- a poppet assembled with the valve body and axially movable in the central cavity of the body housing between a closed position in which a radially extending sealing surface of the poppet seals against the seat seal to prevent fluid flow through the longitudinally extending portion of the flow path, and an open position in which the poppet sealing surface axially separates from the seat seal to permit fluid flow between the first and second end ports.
4 more elements
A poppet subassembly comprising:
- a poppet including a central portion disposed between axially extending upper and lower stem portions, the central portion defining an upward facing radially extending sealing portion and a downward facing radially extending shoulder portion;
- a retaining clip secured above an enlarged foot portion of the lower stem portion;
- and
- a poppet spring disposed around the lower stem portion and captured between the shoulder portion and the retaining clip.
1 more element
A pressure regulator comprising:
- a valve body;
- a poppet disposed within the valve body and including an axially extending upper stem portion and a radially extending poppet sealing portion;
- a loading mechanism assembled with the valve body and operable to apply a downward load force;
- and
- a sensing element disposed between the loading mechanism and the poppet to transmit the load force from the loading mechanism to the poppet;
- wherein a lower end of the sensing element includes a socket receiving an enlarged head portion of the upper stem portion of the poppet, wherein the socket is sized to permit axial movement of the poppet with respect to the sensing element;
- and
- wherein the pressure regulator further comprises an overtravel spring disposed around the upper stem portion of the poppet and compressed between a shoulder portion of the poppet and an end face of the socket.
