Construction and function

The TOP Control on/off serves to drive pneumatically actuated process valves. It may be combined with
various vbalve types from the Bürkert process valve range (see data sheets for types 2000, 2001, 2002,
2012, 2030, 2031, 2031K, 2652, 2655 and 2658).
TOP Control and process valve are connected by an adapter. This results in an integral system consisting
of repeater, actuator and valve function.
Various electrical and pneumatic connection variants are available.
