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 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
