For subplate mounting,
Mounting hole configuration to
ISO 4401-05-05-0-05 with ports X and Y.
Subplates, see page 12
Dry servo motor, no contamination of solenoid gaps by
Non-wearing spool return element
External trigger electronics in modular form, additional
safety barriers (order separay), see Page 6
– Valve is calibrated and tested
– Internal/external control oil supply and return individually
– Spool with flow force compensation
– Control sleeve permanently centered, therefore reducing
sensitivity to temperature and pressure
– Pressure chamber gaps on control sleeve sealed,
ID朎 2 mA ?Ventil ist deaktiviert.
