The Danfoss OSPCX 200-LS is a hydrostatic steering control unit featuring integrated load-sensing priority valve technology. Designed for open-center, non-reaction steering systems in mobile machinery. The unit provides proportional flow to steering cylinders based on operator input while delivering excess flow to auxiliary circuits via the priority valve. Core construction includes a rotary spool and sleeve metering set, torsion bar for feedback, and a built-in relief valve for system protection. The LS port connects to the pump load-sensing signal. Standard SAE 4-bolt flange mounting and SAE O-ring boss ports facilitate installation. Serviceable seal kits available for maintenance.
