Threaded On/Off Valves
Use these valves in general purpose applications such as those with water, oil, air, and inert gas.
Spring-close lever handles automatically close when the lever is released.
Full-port valves do not restrict flow.
Standard-port valves slightly restrict flow.
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.

High-Pressure Threaded On/Off Valves
These valves are rated for at least three times the pressure of standard threaded valves. This makes them ideal for controlling the flow of compressed gas, steam, and high-pressure water spray.
Lever handles are easy to open and close—they give you the most leverage of any handle type. Spring-close lever handles automatically close when you release them, so they’re good where the volume of flow needs to be closely monitored to avoid overflowing and spillage. They’re also called deadman’s handles.
316 stainless steel valves are more corrosion resistant than steel valves.
Standard-port valves slightly restrict flow.

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.
