Hydraulic Steering Unit, Open Center, Non-Reaction, 50CC, With Relief & Anti-Shock Valves
BPBS1-50-A14-Y31-P
Product Features:
Hydraulic Steering Unit 50cc, Open Center Non-Reaction With Relief & Anti-Shock Valves – Direct Replacement for Danfoss OSPC50ON (150-1166 / RV140 SV200)
The BPBS1 hydraulic steering unit features integrated valves, including a pressure relief valve and a anti-shock valve, for enhanced system protection and performance.
Standard configuration: ON (Open Center, Non-Reaction)
- Open Center: Allows continuous oil flow through the steering unit back to the tank when in the neutral (non-steering) position.
- Non-Reaction: Prevents feedback from the wheels from reaching the steering wheel — the steering wheel stays stationary even if external forces act on the wheels (e.g., hitting a rock or curb).

CHARACTERISTICS
Steering units are primarily used in low-speed, off-road vehicles, particularly in the agricultural and construction sectors. They provide smooth, reliable steering performance, enhancing both operator comfort and overall system efficiency. Common applications include construction equipment such as excavators, loaders, and bulldozers, as well as agricultural machinery like tractors, harvesters and sprayers.
- With effective pressure compensation for changes in steering load.
- The steering unit maintains consistent flow and pressure, ensuring reliable steering performance.
- The steering circuit operates independently from other circuits, enhancing overall system efficiency.
- With high steering sensitivity and quick response, the steering performs well even in cold conditions.
OPEN CENTRE STEERING SYSTEM
In an open center steering system, oil from the pump returns to the tank when in the neutral position. A fixed displacement pump is recommended for this setup.
