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.

Pull-activated lever handles open the valve when you pull the handle upward. Attach a cord or chain to the hole in the handle for remote operation.

Push-activated lever handles open the valve as downward pressure is applied.
