High-Performance Machines + Maximum Up-Time

Three functions in one valve: Load-control valves in the CINDY series combine the functions of load-holding, safety and pipe-rupture protection.

Full control of the flow rate

Leak-free load-control valves (CINDY) take over the precision control operations, the leak-free load holding in the rest position, and the safety functions. They prevent hydraulic actuators from running ahead of the available oil supply when they are acted on by an external driving load. Thanks to the particular design of the main control axis, these load-control valves offer extremely low leakage rates.

With this design, the load pressure acts in the closing direction, ensuring safe operation over the entire pressure and flow range, even in the event of a broken spring.

Leak-free load-control valves in this series are also ideally suited for use in high-pressure applications up to 420 bar (6000 psi). Thanks to a variety of optional components, the series can be extended and adapted to the requirements of the system.

Reliable in every way

To control large loads delicately and position them with millimetre accuracy demands a high degree of reliability in every respect. Consequently, no safety valve leaves the factory without rigorous testing. Hydraulic tests are carried out before shipment, and the valve's characteristics are saved so that its condition at the time of despatch can be reproduced.

Applications

Our load-control valves (CINDY) are used in the following applications:

  • Mobile, harbour, and ship cranes
  • Aerial work platforms
  • Fire-fighting turntable ladders
  • Drilling rigs
  • Underground & tunnel boring machines
  • Hydraulic presses
