A Digital Distributor Valve System increase motor capacity 2-3 times, losses are cut in half and the motor becomes controllable.

With Bauer motors, flow capacity follow the number of cylinders:

5 cylinders: 850 lpm

7 cylinders: 1200 lpm

9 cylinders: 1500 lpm

18 cylinders: 3000 lpm

This is 2-3 times higher than the same motors with traditional distributor valves.

Valve blocks

Each valve block have two high-flow, pilot operated poppet valves that connects the cylinder to high or low pressure. Overpressure protection is integrated.

Valve blocks are optimized by CFD calculations to keep flow losses at a minimum. Pressure and temperature sensors are integrated. 


Each motor is equipped with a controller. The controller connects the valves, sensors, communication network and power. The rugged aluminium housing (IP67) is equipped with safety microprocessors and high quality components. Protection against overvoltage, reverse polarity and high temperature.

​Control software

The motor can be controlled in all four quadrants with optimal valve timing. A range of novel control options is included in the software including displacement control, motor locking, freewheeling, over centre control, position control and creep mode. Software development is done according to IEC 61508 on functional safety for the highest safety and reliability.



The controller monitors all important operational data and loads. Data can be stored and used for a range of valuable functions, e.g. service life predictions, condition monitoring, overload protection.
