Load Control Valves CINDY

Description

Whenever loads are to be precisely moved, placed and held, 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.

Advantages

Two-stage load-control valve and bypass check valve are functionally combined in one coaxial valve assemblyLeak-free load holdingPilot ratio 1:113Guaranteed closing force for the load-control assembly ? reliable shut-off even with a broken springVarious pilot-pressure ranges can be chosenSatisfies exacting demands on corrosion protection thanks to zinc-nickel coatingVarious types of pilot control are availablePressure relief is independent of return-line pressureLow-noise operation thanks to specially shaped control grooves
