Abstract
A valve assembly that includes a valve housing and a valve body that is configured to be mated with the valve housing. The valve housing includes at least one window that extends through a wall of the valve housing, and the valve body includes at least one prong that is configured to mate with the window when the valve body is mated with the valve housing.
Claims20
A valve assembly, comprising:
- a valve housing including a first open end defining a valve inlet, and a second open end;
- a valve body having a proximate open end configured to be mated with the second open end and defining a valve seat, and a distal open end defining a valve outlet;
- a movable plunger positioned within the valve housing, the movable plunger defining a valve member that is configured to engage with the valve seat when the valve assembly is closed and be located away from the valve seat when the valve assembly is open;
- and
- a spring positioned between the movable plunger and the valve body, the spring being configured to bias the movable plunger toward the valve inlet,
- wherein the second open end of the valve housing includes at least one window that extends through a wall of the valve housing;
- and
- the proximate open end of the valve body includes at least one prong that is configured to mate with the window when the proximate open end is mated with the second open end of the valve housing.

A valve assembly, comprising:
- a cylindrical valve housing including a first open end defining a valve inlet and a second open end, the cylindrical valve housing defining a first bore;
- a cylindrical valve body having a proximate open end configured to be mated with the second open end and defining a valve seat, and a distal open end defining a valve outlet, the cylindrical valve body defining a second bore having a diameter that is less than the first bore;
- a movable plunger positioned within the valve housing, the movable plunger defining a valve member that is configured to engage with the valve seat when the valve assembly is closed and be located away from the valve seat when the valve assembly is open;
- and
- a spring positioned between the movable plunger and the valve body, the spring being configured to bias the movable plunger toward the valve inlet,
- wherein the second open end of the valve housing includes at least one window that extends through a wall of the valve housing;
- and
- the proximate open end of the valve body includes at least one prong that is configured to mate with the window when the proximate open end is mated with the second open end of the valve housing.
