Claims25
A system, comprising:
- a valve, comprising:
- a valve body having a fluid passage extending between first and second fluid ports;
- and
- a first body assembly disposed in the valve body, wherein the first body assembly is configured to move between first and second positions to adjust a fluid flow through the fluid passage, the first body assembly comprises a first valve seat disposed in a first recess in a first body, and the first body assembly comprises at least one of a first plurality of features comprising:
- a first fluid chamber disposed in the first recess and configured to bias the first valve seat outwardly away from the first body;
- or
- a first spring and a first seal separately disposed in the first recess between the first valve seat and the first body;
- or
- a first retainer removably disposed between the first valve seat and the first body and configured to limit displacement of the first valve seat relative to the first body;
- or
- a first plurality of grooves in the first body within the first recess;
- or
- any combination thereof.

A system, comprising:
- a first body assembly configured to mount in a valve body, wherein the first body assembly is configured to move between first and second positions to adjust a fluid flow through a fluid passage in the valve body, the first body assembly comprises a first valve seat disposed in a first recess in a first body, and the first body assembly comprises at least one of a first plurality of features comprising:
- a first fluid chamber disposed in the first recess and configured to bias the first valve seat outwardly away from the first body;
- or
- a first spring and a first seal separately disposed in the first recess between the first valve seat and the first body;
- or
- a first retainer removably disposed between the first valve seat and the first body and configured to limit displacement of the first valve seat relative to the first body;
- or
- a first plurality of grooves in the first body within the first recess;
- or
- any combination thereof.
7 more elements
A system, comprising:
- a first valve seat configured to mount within a first recess in a first body that selectively moves to adjust a fluid flow through a fluid passage in a valve body of a valve, wherein the first valve seat comprises at least one of a first plurality of features comprising:
- a first fluid chamber configured to bias the first valve seat outwardly away from the first body;
- or
- a first spring and a first seal separately disposed along an inner side of the first valve seat and configured to face the first recess in the first body;
- or
- a first retainer configured to removably mount between the first valve seat and the first body to limit displacement of the first valve seat relative to the first body;
- or
- any combination thereof.
