Pressure [bar]


Flow rate [L/min]


Whenever large loads are to be precisely moved, placed and held, when work access platforms must maintain their position, or when hydraulic presses gates need to withstand high forces, then CINDY load-control valves from Bucher Hydraulics are the right solution. Load-control valves in this series prevent hydraulic actuators from running ahead of the available oil supply. In one valve, they combine the functions of load-holding, safety and pipe-rupture protection. Leak-free load-control valves in this series are ideally suited for use in high pressure applications up to 420 bar (6000 psi) with a safety factor of at least 3. With a variety of optional components, the range can be extended and adapted to the requirements of the system.

  • Leak-free load holding
  • Pilot ratio 1:113
  • The control assembly is guaranteed to close → it closes even with a broken spring
  • Various pilot-pressure ranges can be chosen
  • All exposed parts with zinc-nickel plating
  • Various types of pilot control, matched to your system, can be supplied
  • Low-noise operation thanks to specially shaped control grooves
