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.
Steel valves stand up to corrosion better than cast iron valves. 316 stainless steel valves are more corrosion resistant than cast iron and steel valves.
Full-port valves do not restrict flow. 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.

Compact Flanged On/Off Valves

- Valve Type: Ball
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Steam, Water, Xenon
- Seal Material: PTFE Plastic
- Specifications Met: ASME B16.34, ASME B16.5, ASME B31.1
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.
316 stainless steel valves are more corrosion resistant than steel valves.
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.

Socket-Connect On/Off Valves for Drinking Water


- Valve Type: Ball
- For Use With: Drinking Water
- Seal Material: EPDM Rubber
- Specifications Met: NSF/ANSI 61
Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves meet NSF/ANSI 61, which means they’re safe to use with drinking water systems. They are full port, so they do not restrict flow.
PVC valves are made of the standard material used in most drinking water systems. CPVC valves resist heat better than PVC valves, so they’re better for water systems connected to a heater.
T-handles resist accidental movement when snagged or bumped. Lever handles are easy to open and close—they give you the most leverage of any handle type.
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.
