    Snap-Shut Threaded Flow-Adjustment Valves

    Also known as whistle valves, these open and throttle as force is applied to the lever and automatically close upon release. They’re commonly used for spraying, washing, and other applications that require manual discharge of liquid and air. All have a nonrising stem that stays in the same position whether the valve is open or closed.
