About On/Off Valves
More
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.
