Abstract
A valve including a movable poppet positioned within a valve cartridge and having valve member that is configured to contact a valve seat. A first diaphragm is provided between a first portion of the movable poppet and a first retainer ring, and a second diaphragm provided between a second portion of the movable poppet and a second retainer ring, wherein a fluid flow path that connects an inlet port and an outlet port of the valve cartridge is provided between the first diaphragm and the second diaphragm, and wherein bearing surfaces of the movable poppet that orient the movable poppet relative to the valve cartridge are positioned outside of the fluid flow path such that the bearing surfaces are not exposed to a fluid in the fluid flow path.
Claims16
A valve apparatus, comprising:
- a valve assembly;
- and
- an actuation assembly attached to the valve assembly and configured to open and close the valve assembly,
- wherein the valve assembly includes:
- a valve cartridge including an inlet port, an outlet port, and a valve seat positioned between the inlet port and the outlet port;
- a movable poppet positioned within the valve cartridge and having a valve member that is configured to contact the valve seat when the valve assembly is closed and be spaced apart from the valve seat when the valve assembly is open;
- a first diaphragm provided between a first portion of the movable poppet and a first retainer ring;
- and
- a second diaphragm provided between a second portion of the movable poppet and a second retainer ring,
- wherein a fluid flow path that connects the inlet port and the outlet port is provided between the first diaphragm and the second diaphragm,
- wherein bearing surfaces of the movable poppet that orient the movable poppet relative to the valve cartridge are positioned outside of the fluid flow path such that the bearing surfaces are not exposed to a fluid in the fluid flow path,
- wherein a fastener is connected to the movable poppet, the fastener and the movable poppet collectively define the second portion of the movable poppet, and another of the bearing surfaces of the movable poppet that is positioned outside of the flow path is between the fastener and the second retainer ring, and
- wherein the fastener includes a shank threadingly engaged with the an end of the movable poppet, and a head attached to the shank, and wherein an interface between the head and the second retainer ring defines one of the bearing surfaces of the movable poppet.
