About On/Off Valves
More
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.
Push-lever valves are commonly used in car wash systems. However, you can’t use them as blow guns.
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.

Noncontact Flow-Adjustment Valves
- Valve Type: Pinch
- For Use With: Water, Oil, Air, Deionized Water, Diesel Fuel, Ethylene Glycol, Fuel Oil, Isopropyl Alcohol, Kerosene, Methanol, Mineral Spirits, Sodium Hydroxide, Sodium Hypochlorite
Also known as pinch valves, these press down on the outside of tubing to adjust flow without contacting the process media. They can be used with any media that’s chemically compatible with your tubing.
Valves with an open body provide easy access to tubing for maintenance or replacement.
Valves with a closed body securely hold tubing in place.
