• a valve sealing element positioned inside the valve body;
• a stem positioned inside the stem bore of the valve body, the stem comprising a first end and a second end, the first end of the stem engaged with the valve sealing element;
• and
• a cap fixed with respect to the stem and thereby prevented from translational or rotational movement 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;
