Valves
Pneumatically and mechanically actuated process and media valves
Festo pneumatically and mechanically actuated process and media valves control liquids, gases, and non-lubricated compressed air in process plants where electrical control power is not available or permitted. The VAPB ball valve series covers pipe connections from G 1/4 to G 1 1/2 and is actuated by a pneumatic rotary actuator that converts 0-90° rotation into a defined open or closed position. ISO flange connections F03, F04, and F05 allow direct mounting of standardised actuators.
