Snap-Shut Threaded On/Off Valves
For applications that require intermittent operation, such as spraying and washing, push or pull the lever on these valves to start flow. They spring closed when the lever is released.
Zinc valves are good for low-pressure applications. Use them as a control valve for tools such as blow guns and tire-changing machines.
Brass valves are stronger and less brittle than zinc valves for use in higher-pressure applications.
Push-lever valves are commonly used in car wash systems. However, you can’t use them as blow guns. Those with a Viton® fluoroelastomer rubber seal stand up to long-term use with harsh solutions, such as wheel and tire cleaners. Valves with a TFE plastic seat are more durable than those with a Viton® fluoroelastomer rubber seat. For even more durability, choose those with a thick spring—their spring is stronger and lasts longer than standard springs. You can install valves with a mounting stem and nut in a fixed position. Valves with offset ports come with a wand bracket to attach an upholstery cleaning wand, so they’re best for floor and upholstery cleaning equipment. Connect the bracket to the top of the offset ports.
Replace worn components on 30° elbow valves with a repair kit (sold separately).
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

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.
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.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
