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.
