Improved Controller for Rexroth AHC
New DS2R electrohydraulic controller with proportional valve is now available for the Rexroth hydraulic axial piston units that function as secondary control devices in offshore winch applications. Bosch Rexroth has introduced an upgrade to the electrohydraulic controller used on the company’s A4VSO and A4VSG hydraulic axial piston components, which function as secondary control units in the Rexroth Active Heave Compensation (AHC) system for offshore winching applications. Replacing the previous DS1 model, the new Rexroth DS2R electrohydraulic controller features proportional valve technology for more reliability, easier maintenance and lower cost. The controller is fitted directly to the secondary control unit – axial piston equipment that can serve as both a pump or motor to effectively manage variations in torque on winch drives in rotary AHC systems.
