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.

Threaded On/Off Valves for Refrigerant
- Valve Type: Ball
- For Use With: Refrigerant
- Seal Material: PTFE Plastic
- Specifications Met: NACE (National Association of Corrosion Engineers) MR0103, NACE (National Association of Corrosion Engineers) MR0175
Often used in HVAC or refrigeration systems, these valves are designed to control the flow of ammonia, nitrogen, and other harsh chemicals. To prevent accidental spills, a spring on the handle will automatically close the valve if you lose your grip. It’s also known as a deadman’s handle. The ball has a vent to relieve gas buildup when the valve is closed. Made from 316 stainless steel, these valves have excellent corrosion resistance.
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.

Threaded Gradual On/Off Valves
Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.
Valves with a spring-close lever handle open when you pull on the handle and close when you release it. The handle is also called a deadman’s handle. Use these valves where the volume of flow needs to be closely monitored to avoid overflowing and spillage. Valves with a nonrising stem keep the stem in the same position whether they’re open or closed. They’re often used underground and in low-clearance locations.
Brass valves have good corrosion resistance. They also have a more polished look than bronze valves. However, they’ll corrode from salt water.
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.
