Direction Control
Solenoid Operated Directional Control Valve (CETOP 03) - DE 06 (315 bar, 63 lpm)
 

Direct solenoid operated, spool type, mounting on ISO 4401-03-02.

Five chamber body and spool design provides low-pressure drop, with maximum performance. Balanced spool design ensures proper shifting force for maximum reliability and long life. All spools and bodies are interchangable, simplifying maintenance. Wet pin DC solenoids ensure better heat dissipation, quitter operation, there by increasing solenoid life. Moulded solenoid coils eliminate moisture problems and ingress of dust. Plug-in-coils for ease of maintenance. Indicator lights are a standard option.

 
Solenoid Operated Directional Control Valve
 
Solenoid Operated Directional Control Valve (CETOP 05) - DE 10 (315 bar, 120 lpm)
 

4-port, spool type, solenoid operated, directional control valves with wet armature AC or DC coils and wide variety of spool types with spring centered and spring-offset arrangements.

 
Five chamber body and spool design to facilitate high flow.
Conforms to ISO4401-5, NFPA T3.5.1M R1 and ANSI B93-7 D 05 interface.
Available in 52 standard, interchangeable spool configurations.
Removable wet-armature AC and DC solenoids for quick replacement and conversions. Moulded solenoid coils to protect against moisture and ingress of dust.
Individual solenoid plug-in connectors with indicator lights to ISO 4400 and DIN 43650.
Special R-rings for high extrusion resistance. Increased stability under high dynamic condition.
Override for operation of valve without electrical power.

Throttle / Check Valve
 
Pilot operated check valve (Modular) - CIM 06
 

These modular valves are available with the pilot operated check valve facility on either 'A' or 'B' ports. The hydraulic opening operation for free flow in reverse direction is achieved by means of internal pilot pressure available from the other working port. Interface conforming to
ISO 4401-AB-03-04-A
IS 10187
DIN 24340
To ensure proper closure of both valve poppets, both user connections should be unloaded when the control valve is in the neutral by connecting with the return line.
