Description
The Domin S10 Pro is the most efficient direct-drive high-flow servo valve in its class, replacing bulky conventional servo valves with a significantly more compact and lighter solution. With a nominal flow rate of up to 250 l/min and a high control bandwidth, it is particularly suitable for energy-intensive applications such as hydraulic presses, turbine test benches, railway technology and large-scale test systems. The integrated on-board electronics with spool position feedback eliminate the need for an external amplifier.
Technical highlights
- Direct-drive servo valve (rotary-linear), size NG10
- Integrated on-board electronics with slide position feedback – no external amplifier required
- Response time under 7 ms, frequency response above 140 Hz (–90° phase, up to 170 l/min)
- Hysteresis less than 0.2 per cent, threshold less than 0.1 per cent
- Nominal flow rate 50 to 250 l/min (rated at 70 bar ΔP), maximum flow rate up to 475 l/min
- Maximum operating pressure 350 bar (P, A, B) / 250 bar (T)
- Chip shear force in excess of 700 N – exceptional tolerance to contamination
- Leakage of less than 1 l/min (50–170 l/min) or less than 3 l/min (170–250 l/min) at 100 bar
- Supply voltage 22–30 V DC, peak current 8 A (fuse rating 10 AT)
- Vibration resistance: 30 g (all axes); shock resistance: 50 g
- ISO 4401-05-04 mounting interface, tightening torque 13 Nm
- Valve mass: 4.0 kg
