About On/Off Valves

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.

Fast-Acting Threaded On/Off Valves
Push a button or flip a toggle switch to start or stop flow. Often used in testing and sampling, these valves are useful when you need to dispense a small amount of liquid.
Nickel-plated brass valves resist corrosion better than plain brass valves.
Push-button valves automatically open or close when you take your finger off the button. They’re ideal for intermittent use and applications where you want to monitor flow closely to avoid spills. The button is colored to make it easy to tell different valves apart. Normally open valves close when you push their button. Normally closed valves open when you push their button.
Toggle valves stay open until you flip them closed. Since they don't need to be held open, they’re often used to dispense larger samples than push-button valves. You can see if these valves are open or not based on the toggle's position.
Valves with an exhaust port release extra air or liquid when they close. When these valves open, the exhaust port closes.
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.

Fast-Acting Panel-Mount Threaded On/Off Valves

Start or stop flow with the flip of a toggle switch or the push of a button. These valves are often used in testing and sampling applications where you need to dispense a small amount of liquid. They fit through a cutout, so the body of the valve stays safe inside your instrumentation panel.
Nickel-plated brass valves resist corrosion better than plain brass valves. 316 stainless steel valves stand up to corrosion better than both plain and nickel-plated brass valves.
Manual-return valves stay open until you flip the toggle off. Since they don't need to be held open, they’re often used to dispense larger samples than spring-return valves. It’s also easy to check if these valves are open or not based on the toggle’s position. Spring-return valves automatically close when you release the toggle or push button. They’re ideal for intermittent use and precise flow control to prevent spills.
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.

Swivel Threaded On/Off Valves
Make connections from any direction—the body of these valves swivels 360° for easy installation. Often used in testing and sampling applications, they quickly open and close with a toggle or button.
Toggle-switch valves stay open until you flip them closed. Since they don’t need to be held open, they’re often used to dispense large samples. The toggle’s position shows you if they’re open or closed.
Push-button valves open when you press the button. When released, the button springs back and automatically stops flow. They’re ideal for intermittent use and controlling flow to avoid spills.
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.

Fast-Acting Panel-Mount On/Off Valves with Yor-Lok Fittings


- Valve Type: Stem
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon
- Seal Material: PTFE Plastic
Flip the toggle to quickly turn these valves on and off. All have threads and a hex nut below the handle for installation in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.
316 stainless steel valves are more corrosion resistant than brass valves.
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.
