Controls, working and additional hydraulics

Mobile controls as a complete package of: hydraulics, sensors, electronics and software; everything from one source or as individual components.

HYDAC offer mobile valves for standard actuation types (manual, hydraulic, pneumatic, electronic or electro-proportional) on different hydraulic circuits and options. Whether in open or closed circuits, in monoblock or disk construction, or a combination of the two; also available with load-sensing controls. In this way we have created a modular system for flexible design of your complex controls up to approx. 180 l/min and for pressure ranges of up to 350 bar.

  • Constructional design as monoblock, in disk construction or a combination of the two,
  • setting functions with and without load pickup,
  • use with constant or adjustable pump possible,
  • a multitude of control valve pistons and characteristics is available,
  • main consumer in parallel or series switching,
  • easy integration of secondary functions,
    • of load-holding and load-lowering brake valves,
    • of the priority valve for steering (OC or LS steering),
    • of the priority valve for the brake system with integrated accumulator charging function
    • of pressure filters and accumulators (for emergency functions),
    • of pressure and position sensors,
    • Level control

Front loader control blocks and 6/2 change-over valves

The new HYDAC front loader control blocks RMA and RMB have been especially developed for applications with front loaders.

  • All hydraulic and electrical connections are applied to the flange surface for quick changes. The valves are highly universal and can be used both in open center and in load-sensing controls, or with fixed displacement pumps or variable displacement pumps.
  • Due to appropriate construction and high production quality, the internal leakages have been reduced to a minimum, meaning that any sinking of the front loader is almost unnoticeable.
  • If required, we can provide special functions, for example floating position.
  • In combination with the change-over valve block RV, the integrated bucket damping is also available, and the actuation of another function (special function) is possible.
  • Combination with directional valve MWV6/2 possible.

Priority valve

The mobile priority valve MPV or the DW12P (priority pressure compensator) are used where hydraulic functions have to operate with priority, e.g. steering or braking.
The primary function is supplied in priority from the pump once it is initiated. The remaining oil flow can be used for other functions.

Cabin suspension

The FDE spring damper element, is a standard element for hydropneumatic suspension of the vehicle cabins with adaptive damping and
level regulation for complete utilization of the spring deflection. The extremely low-friction suspension cylinder especially developed for this application has been designed for vertical loads of up to 300 kg. The system alignment can be carried out to specific customer requirements.

Suspension systems

For increased comfort and driving stability. Load-independent, hydropneumatic chassis suspension with level regulation, axis lifts, blocking function, roll stabilization and automatic error indication. Optimum alignment of the vehicle to the loading condition (level regulation).

Cooling systems

High-performance and installation-optimized cooling systems for fulfillment of the legal
requirements for noise, emissions (EURO 5, TIER 4) and fuel savings.

  • Integrated thermo-bypass valves
  • Electric / hydraulic ventilation drives with proportional speed control
  • Oil/air coolers
  • Multiple combination cooling systems
  • Tank-filter integration

Filtration solutions

A comprehensive range of hydraulic and breather filters equipped with
high-quality filter element materials ensure high operating safety and long maintenance intervals, for example:

  • Return filtration with return filter RFM. Tank-mounted or tank-integrated filters.
  • Feed circuit filtration with line filter LPF.
  • Pressure filtration with line filter MFM.
  • Transmission oil filtration Suction filter for transmission and hydraulic oil
  • Removal of coarse particles with Inline Filter ILF.
  • Air filtration with ventilation filters BF, ELF, ELFL, BD: wide standard range of products, optional with duo valve for tank pre-tension, anti-swash protection possible, version with air drying function.
  • Filter clogging indicators for the improvement of operating safety and, if applicable, display of maintenance intervals.
  • Brand labeling to ensure availability of spare parts Marking of the filter elements for improvement of the product identification and to ensure replacement element availability.

Transmission shift control

Proportional pressure reducing valves in the gear transmission shift block ensure gentle shifting between the gears: quick drive (road), slow drive (terrain) and reverse gear for mobile applications.

Customer-specific central hydraulics

Here individual components such as valves, accumulators, filters and partial systems can be integrated together into one block.

The advantages:

  • Space-saving
  • Reduction of leakage outwards
  • Reduced assembly time and effort
  • Economic with material
  • Tailored to the specific installation situation
