Abstract: A method of assembling a valve includes inserting a stem of the valve into a valve body of the valve through an end of the valve body, the stem defining a first end engaged with the valve body; securing a fastener to a second end of the stem; and placing a cap of the valve over the second end of the stem, the fastener engaging the cap.

Abstract: A valve includes a valve body; a valve sealing element positioned inside the valve body; a stem positioned inside the stem bore of the valve body and engaged with the valve sealing element; and a cap fixed with respect to the stem, the cap comprising a mounting end and an actuating end; the mounting end defining a stem engagement cavity; the actuating end distal from the mounting end; the cap defining a first side surface, a second side surface, and a top surface; the cap defining a window in a position between the mounting end and the actuating end; the window defined in and extending from one of the first side surface, the second side surface, and the top surface; and the window exposing a surface of the stem but preventing passage of the stem through the window.

Abstract: A cap for a valve includes a mounting end defining a lower cavity and a stem engagement cavity therein; and an actuating end distal from the mounting end and comprising a rotation tab, the rotation tab defining a surface defining a window exposing the stem engagement cavity. A method of manufacturing a valve includes inserting a stem of the valve into a valve body of the valve through an end of the valve body; placing a cap of the valve over an end of the stem, the end of the stem engaging a mounting hole of the cap; and checking the vertical position of the stem relative to the cap through a window defined in a surface of the cap that exposes the stem.
