Solenoid operated valves are used to control the connected hydraulic cylinder by means of a pendant remote control or further electrical controls like pressure switches or limit switches.
Control principle
All solenoid valves have 3 positions:
- advance - stop - retract -
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 remote mounted by using hydraulic piping.
Design
Long life direct controlled ball seal valves with leakfree “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).
Modular design
The modular principle allows special valve configurations e.g. control of multiple cylinder systems or specific control sequences.
Pressure adjustment
All solenoid valves are equipped with a precisionadjustable pressure set valve which allows the system pressure (force of cylinder) to be limited to any value from 0 to 700 bar.
Pressure gauge
A glycerine-damped pressure gauge GGY-631 is standard with solenoid valves, 0-1000 bar, Ø 63 mm.
