-
Version with axial piston variable displacement pump A10VSO.../31
-
Size 18 … 140
-
Component series 2X
-
Maximum operating pressure 280 bar

A SYDFE1-2X control system is used for the electro-hydraulic control of swivel angle, pressure and power (partially optional, see type key pilot control and preload valve and ordering code) of an axial piston variable displacement pump.
The control system consists of the following components: - Axial piston variable displacement pump A10VSO.../31
- VT-DFP-.2X proportional valve as pilot valve including inductive position transducer for valve position sensing.
- External control electronics VT 5041-3X for realizing all electric functions necessary for the SYDFE1-2X (separate order)
- Position transducer for sensing the swivel angle
- Pressure transducer with suitable signal level and dynamics (optionally HM 20, otherwise separate order)
- Preload valve with integrated pressure relief function SYDZ (optional)
