Maximator® air operated valve actuators are piston type design, and are mounted on a manual valve to provide remote control capability. There are two styles of air actuators available, and selection is based on the valve size, system pressure, and air pressure available.

Select the basic manual valve from the appropriate pressure section, then add the actuator suffix number to the end of the manual valve catalog number.
