Product description

The hydraulic system of an excavator is normally consisting of two hydraulic circuits. A high-pressure circuit (210-400 bar) for the work hydraulics and a low pressure circuit (20-40 bar) for the control of the work hydraulics (Pilot circuit with main control valves).

Depending on the type of machine and conception of the hydraulic system, HYDAC pressure reducing valves, solenoid valves in black/white or proportional technology, accumulators, filters and pressure sensors are arranged to a pilot oil circuit. All these components are united in one manifold.

HYDAC customized manifolds are weight and Dp optimized designed. All components are manufactured in house.

HYDAC pilot control units are characterized by high switching safety and small leakage of the solenoid valves whereby the energy in the accumulator is longer at disposal at motor-downtime for emergency functions. Different plugs and IP-ratings (up to IP69K) are available.

Proportional pressure reducing valves with small hysteresis and high repeatability enable an exact control of the power limit control of axial piston pumps of the work hydraulics. The behaviour of these valves could be specially adjusted to the corresponding pump type.

Flanged-on modules are making the pilot manifold a flexible system which allows the customer to retrofit optional functions easily.
