Model Code – K(A)*G4V-3 High Performance Valves
Warning: To conform to the EC Electromagnetic Compatibility directive
(EMC), this KADG4V or KATG4V valve must be fitted with a metal 7-pin
plug. The screen of the cable must be securely 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. The plastic plug, part no.
694534, is only suitable for use in a sealed electromagnetic environment or outside
of the European Community
Spool flow rating

P→B→A→T: ∆p= 10 bar (145 psi).
For single flow path P→A or B→T:
∆p= 5 bar (72 psi).
