A. Main-Spool Options
Spools shown are meter-in/meter-out
types. Center-condition options are
types 2 and 33.
B. Internally Piloted Models Differ from detailed symbols above by omission of plug n and the blocking of port X by the mating surface.

To conform to the EC Electromagnetic Compatibility directive (EMC) this KA valve must be fitted with a metal 7-pin plug. The screen of the cable must be curely connected to the shell of the metal connector. A suitable IP67 rated connector is available from Vickers, part no. 934939. Alternatively a non IP67 rated connector is available from ITT-Cannon, part no.CA 02 COM-E 14S A7 P .
Additionally the cable must be fitted with a ferrite EMC suppression core not more than 4cm from the connector referred to above. Suitable types include Farnell 535-898 or Farnell 535-904 which snap fit over the cable.大寒日
The plastic plug, part number 694534, is only suitable for u in a aled electromagnetic environment or outside of the European Community.
