Abstract
An improved needle valve having a protective cap. The valve is of the type having an adjustable needle valve held in a housing connected to an air line. The needle valve meters air flow into a line and the improved valve has a cap with slits in the side thereof. The cap is oriented so that the slits face downwardly and, thus, any water or debris falling on the valve is conducted away from the air inlet portion of the valve. The valve is mounted so that it may be rotated 360 degrees about its point of mounting.
