Pilot operated solenoid valves

Product Information

Functional principle

With only 1 W power consumption pilot operated solenoid valves series 63.1 V switch flows of more than 270 l/min of air! This is possible due to a solenoid valve series 63.1 that controls the underlying main valve at two bar pilot pressure over an air bypass. The nominal pressure on application side may be up to eight bar at the same time.

The well-proven design and long-term production expertise result in a secure switching of the valve and its reliable function during the whole lifecycle. Before leaving our production facilities, all valves pass a test for functionality and leakage. The cost-efficient design allows a usage for small up to high series demands.

These often-called “pilot valves” are available as 3/2-way NC (normally closed) and NO (normally open) valves. We supply different electrical connection options such as pins, wires or connectors. Either 24 V DC or 12 V DC are the choice for standard nominal voltage. The pneumatical connection is a flange connection.

The manual override facilitates the commissioning of the series 63.1 V valve in any application. The override is offered as rotary knob to be adjusted via flat-tip screwdriver or as “paddle” for the use without additional tools.

Well-proven sealing and housing materials allow the use in the most different production environments. In addition, if needed all technical parameters are adaptable to customers and application requirements.


Due to their outstanding technical and commercial properties, the pilot operated solenoid valves series 63.1 V became a well-known component for control heads in process valves. As one of the core components, they switch pressurized air to control single- or double-seated valves in matrix-piped power plants, processing liquids such as beer or milk.

All automated processes in breweries, dairies and other liquid and food processing power plants demand the secure function and long lifetime of all its components to prevent from production losses and downtimes. At the same time, manufacturers face an extremely competitive environment. Pilot operated solenoid valves series 63.1 V contribute to the best possible price ratio.

The full potential of series 63.1 V valves leads to any other imaginable application where high flows are required to control pneumatic actuators like cylinders or rotary drives. - Thanks to their compactness and low power consumption.
