700 bar incl. pressure set valve
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 connected by using hydraulic piping.
Design
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).
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 precision-adjustable 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, O 63 mm.
Mounting flange
The valve flanges are designed in a way that valves (with pressure connector) can easily be mounted onto power packs.
Option
The connector model FY-905 is to be ordered separately.
