About On/Off Valves

Flanged On/Off Valves
Bolt these valves to ANSI flanges. Their lockable lever handle can be fixed in place using a padlock (not included). All have four mounting holes to install an actuator, so you can convert them from manual to automatic valves.
316 stainless steel valves are more corrosion resistant than cast iron and steel valves.
Standard-port valves slightly restrict flow.
Pressure class 150 valves are standard and work for most low-pressure applications.
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.

Also known as wafer ball valves, these combine the slim body of a butterfly valve with the high flow rates of a flanged ball valve. Bolt these valves to ANSI flanges—they meet ASME standards for dimensions, material, and pressure-temperature rating. They are full port, so they do not restrict flow.
