Leak-Free Load-Control Valve series CINDY 20-B-S
Flow rate [L/min]
Whenever large loads are to be precisely moved, placed and held, or work access platforms must maintain their position and withstand high forces, then leak-free load-control valves from the CINDY series 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 variety of optional components, the series can be extended and adapted to the requirements of the system.
- Two-stage load-control valve and bypass check valve are functionally combined in one coaxial valve assembly
- Leak-free load holding
- Pilot ratio 1:113
- Guaranteed closing force for the load-control assembly → reliable shut-off even with a broken spring
- Various pilot-pressure ranges can be chosen
- Satisfies exacting demands on corrosion protection thanks to zinc-nickel coating
- Various types of pilot control are available
- Pressure relief is independent of return-line pressure
- Low-noise operation thanks to specially shaped control grooves
