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. Use with water, oil, air, steam and inert gas such as helium.

Bolt these valves to ANSI flanges—they meet ASME dimensional standards. They have a plastic body and a seal that withstand aggressive and corrosive solutions in chemical-processing applications.

With a ball-valve design, these valves can handle three times the flow of butterfly valves.

For three times the flow of butterfly valves, these have a ball valve design.

Bolt these valves to flanges. Use them with water, oil, air, and inert gas. All operate on compressed air to automatically divert flow between ports more quickly than motor-driven valves. You must control the air to the actuator using either an electric pilot valve or a manual on/off valve.
