All solenoid valves have 3 positions: ‒ advance ‒ hold ‒ return ‒ In neutral position (stop) the valves switch to “pressureless circuit” so that the oil flow is guided back to the reservoir while the connected cylinder is safely held under pressure. Normally, solenoid valves are mounted directly onto power packs but can also be connected by using hydraulic piping
Long-life, direct-control ball seal valves with leak-free “load hold function” in neutral position. The solenoids guarantee a very quick reaction of the valves so that cylinders can be controlled millimeterwise. The valves are suitable for continuous operation (100 % on/off duration.
The modular principle allows special valve configurations e.g. control of multiple cylinder systems or specific control sequences.
All solenoid valves are equipped with a precision-adjustable pressure set valve which allows the system pressure (force of cylinder) to be limited to any value from 0 to 700 bar.
A glycerine-damped pressure gauge GGY-631 is standard with solenoid valves, 0 - 1000 bar, Ø 63 mm.
The valve flanges are designed in a way that valves (with pressure connector) can easily be mounted onto power packs.
The connector model FY-905 is to be ordered separately.
