Abstract: A valve assembly for mounting on a substrate via rotational engagement with a base of the valve assembly, and a cap for such a valve assembly. A body of the cap is rotatably engageable with the base between opposing first and second terminal ends. At each of the first and second terminal ends, the body and the base abut each other to prevent rotation between the body and the base. As a result, torque applied to the cap is transmitted to the base to vary rotational engagement of the base with the substrate. A slot formed in the cap may be suitable to receive a protrusion on the base and may fork into two separate portions that terminate in opposing terminal ends to allow selective engagement of the protrusion with the two portions. The protrusion abuts against the terminal ends to transmit torque from the cap to the base.
