Abstract:
Embodiments of a valve having a housing including an inlet, an outlet, and an interior chamber in fluid communication with the inlet and the outlet are disclosed. The valve also includes a seat fitting having a first screen held in place by a first retainer ring. The seat fitting includes a valve seat. The valve further includes an outlet fitting having a second screen held in place by a second retainer ring. The second retainer ring includes a plurality of ribs extending from a ring body such that the plurality of ribs create a gap between the ring body and the second screen. Further, the valve includes a valve plug configured to selectively engage the valve seat to open and close a passage between the interior chamber and the outlet. The seat fitting is contained at least partially within the outlet fitting to define the outlet of the housing.
