About On/Off Valves

High-Pressure Threaded On/Off Valves
Rated for at least three times the pressure of standard threaded valves, these valves are used to start and stop the flow of compressed gas, pressurized water, or steam.
Lever handles are easy to open and close—they give you the most leverage of any handle type. Lockable lever handles can be fixed in place using a padlock (not included). 316 stainless steel valves are more corrosion resistant than steel valves.
Full-port valves do not restrict flow. Standard-port valves slightly restrict flow.
