A Wide Range of Steering Units Components | Slimline Hydrotek

They began producing hydrostatic steering units back in the 1960s. Since then they have introduced many new variants, adapting to both market and regulatory needs.

Danfoss is one of the largest producers in the world of steering components for hydrostatic steering systems on off-road vehicles. Danfoss offers steering units solutions both at component and system levels. Our product range makes it possible to cover applications of all types, ranging from ordinary 2 wheel steering (also known as Ackermann steering) to articulated steering, automatic steering (for example, by sensor) and remote controlled steering via satellite. We can offer more than 1,800 different steering units and 250 different priority valves categorised in types, variants and sizes. 

 

For hydrostatic steering systems, Danfoss offers:

 

  1. Mini steering units with displacements from 32 to 100 cm3 /rev [1.95 to 6.10 in3 /rev], flow up to 20 l/min [5.28 US gal/min], steering pressure up to 140 bar [2030 psi]. 

  2. Steering units with displacements from 40 to 1200 cm3 /rev [2.44 to 73.2 in3 /rev], flow up to 100 l/min [26.4 US gal/min, steering pressure up to 240 bar [3481 psi]. 

  3. Priority valves for rated flows at 40, 80, 120, 160 and 320 l/min [10.6, 21.1, 31.7, 42.3 and 84.5 US gal/ min], pressure up to 350 bar [5076 psi]. 

  4. Pilot operated flow-amplifiers with amplification factors of 4, 5, 8, or 10 for rated oil flows of 240 and 400 l/min [63.4 and 105.7 US gal/min], steering pressure up to 240 bar [3480 psi]. 

  5. Pilot operated steering valve with steering flow up to 100 l/min [26.4 US gal/min], steering pressure up to 250 bar [3625 psi] and with integrated priority valve for pump flow up to 120 l/min [31.7 US gal/ min]. 

For electrohydraulic steering systems Danfoss offers:  

  1. Pilot operated steering valves (pilot operated by hydrostatic steering unit or by electrical signal) with steering flows up to 100 l/min [26.4 US gal/min], steering pressure up to 250 bar [3625 psi]. 

  2. Steering units with integrated electrical operated steering valve with steering flow up to 50 l/min [13.2 US gal/min], steering pressure up to 210 bar [3045 psi]. 

  3. Electrical operated steering valve with steering flow up to 70 l/min [18.5 US gal/min], steering pressure up to 210 bar [3045 psi]. 

Characteristic features for steering units: 

  1. Low steering torque: From 0.5 Nā€¢m to 3 Nā€¢m in normal steering situations 

  2. Low noise level 

  3. Low-pressure drop Technical Information OSPB/C/F/D/L LS Steering Units, OLS Priority Valves, OSQ Flow Amplifiers A wide range of steering components Ā© Danfoss | October 2019 11007611 | BC00000009en-000901 | 5
