Threaded On/Off Valves
Use these valves in general purpose applications such as those with water, oil, air, and inert gas.
Short lever handles, lockable oval handles, and T-handles resist accidental movement when snagged or bumped.
Full-port valves do not 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.

Threaded On/Off Valves with Gauge Port
- Valve Type: Ball
- For Use With: Air, Water
- Seal Material: Fluoroelastomer Rubber
- Specifications Met: C-UL Listed, CSA Certified, CSA-US Certified, UL Listed
Attach a gauge to the side port on these valves to monitor pressure, temperature, and other measurements in your line. The port can also be used to drain and divert liquid. These valves are full port, so they do not restrict flow.
Lockable handles can be fixed in place using a padlock (not included).
Oval handles have the largest gripping surface of any handle type, so they’re the easiest to grip when slippery.
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.
