    a second valve part rotatably mounted to the first valve part about the longitudinal axis, the second valve part including a mating portion adapted to cooperate with the tubular portion of the first valve part to close the air inlet and the fluid outlet apertures of the first valve part when the second valve part is in a first position relative to the first valve part, and to open the air inlet and the fluid outlet apertures of the first valve part when the second valve part is in a second position relative to the first valve part; and

    at least one locking tab extending from the second valve part, and at least one arcuate slot including a locking notch at one end of the arcuate slot positioned on the first valve part, wherein the locking tab is positionable in the locking notch to lock the second valve part and the first valve part from relative rotation, and wherein the locking tab is positionable in the arcuate slot to permit relative rotation between the second valve part and the first valve part.
