• Flow max. 40 l/min
• Nominal sizes NG4, NG6

ROV CONTROL VALVES FOR WATER DEPTH UP TO 6000 M FEATURES
The valve utilisation in ROVs (Remotely Operated Vehicle) in
the underwater area requires a resistance to a high external
pressure.
CHARACTERISTICS
• Different solenoids with pressure compensation bore
• With screw terminal connections
• Potted loose cables without connectors
• Status display by means of LED

ELECTRONICS SD7 CHARACTERISTICS
Digital controller module for regulating position, pressure or

volume flow including integrated amplifier.

FEATURES
• Controller mode selectable: pressure, position, speed
• Solenoid current regulated, with superimposed dither
• Command and feedback values as voltage or current
• Up to 7 digital inputs and up to 4 outputs

• Optionally with fieldbus (CANopen, Profibus DP, HART)

• Housing for dome rail mounting
• SSI interface
• Analog output
