About On/Off Valves

Threaded On/Off Valves
Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.
Plated brass valves are more corrosion resistant than plain brass and bronze valves. Full-port valves do not restrict flow. Standard-port valves slightly restrict flow.
FM-approved valves are used in fire suppression systems. They help isolate parts of water supply systems in buildings and plants.
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.

- Valve Type: Ball
- For Use With: See table
- Seal Material: See table
- Specifications Met: See table
Lever handles give you the most leverage for quickly opening and closing valves with minimal effort.
