1 ) To have a long service life for the component, we strongly suggest the fluid should be well-filtered frequently.
2 ) Please comply with European Standards DIN EN 563 and DIN EN 982 must be taken into account!

Com. value ： Positive command value (0 to 1 0 V or 12 to 20 mA) at D and reference potential to E causes flow
from P to A and B to T. Negative command value (0 to 10 V or 12 to 4 mA) at D and reference potential to E causes flow from P to B and A to T. For valves with a solenoid on side “a” (spool variants EA and WA) a positive command value at D and reference potential to E (NS 6: 4 to 20 mA and NS 10:12 to 20 mA) causes flow from P to B and A to T.
Actual value ： The actual value (0〜10V or 12mA) on the F.C enables the connection from port P to port A.
Connection cable Recommendation:
-up to 25 m cable length type LiYCY 5 x 0.75 mrrr
-up to 50 m cable length type LiYCY 5 x 1.0 mm External diameter 6.5 to 11 mm Connect screen to PE only on the supply side
