- outstanding fine control from optimised, low−flow control notches
- high resolution, thanks to the long control stroke - the valve is guaranteed to close, even with a broken spring
- low−noise operation thanks to multiple, specially shaped notches - very low hysteresis - various pilot pressure ranges can be chosen - various types of pilot−control are available

- damping properties guarantee a stable system even in sensitive applications
- additional asymmetric damping properties can be provided - H-igh power density
Advantages of the Cindy load control valve
- absolutely zeroleakage loadholding
- 420 bar working pressure with 3−foldsafety - pilot operated load−control valve and bypass check valve both combined in one axis - Load does not accelerate in the event of a hose burst (with back pressure−independent models) - the opening action is almost entirely independent of the load pressure (area ratio 1:113) - above 100 bar load pressure, it controls like a compensated 2−way flow controller (patented follower principle) - fully compensated pressure relief valve opens independently of tank− or return line back−pressure - over−compensated models are available with various reducing stages
