OSPFSteering Units OSPF 80/100/125/160/200/315/400
1. Steering safety and control
The OSPF Steering Units are designed to effectively control negative steering forces and minimize the risk of uncontrolled movements - even in systems with a single differential cylinder on articulated vehicles. It also provides smooth and sensitive steering control for a wide range of mobile machinery.
2. High performance and efficiency
Capable of achieving higher maximum steering speeds, the performance of the OSPF Steering Units is primarily limited by the hydraulic pump capacity and system pressure. The units operate quietly, making them ideal for comfort-oriented or noise-sensitive environments.
3. Integrated valve flexibility
OSPF hydraulic Steering Units offer one or more built-in hydraulic functions for enhanced versatility: pressure relief valves, damping valves and suction valves are available on both the left and right ports (L + R), and check valves are integrated in the pressure (P) and load sensing (LS) lines to ensure system reliability and protection.
OSPF LS Dynamic steering units in the table below incorporate all the following valve functions:
• check valve in P-port
• pilot pressure relief valve
• shock valves
• suction valves
