Description
The Domin P6 Pro is a compact, direct-drive servo-proportional valve in the NG06 size class, designed for precise control tasks in small and medium-sized industrial plants. With its fast response, fine resolution and a weight of just 630 g, it is ideally suited to machines that require precise motion control within a confined installation space. As a drop-in replacement, it can be integrated into existing NG06 platforms without the need for modification. Typical applications include injection moulding machines, the ceramics industry and automated handling systems.
Technical highlights
- Direct-drive servo-proportional valve, nominal size NG06 – drop-in replacement for existing NG06 systems
- Integrated electronics with slide position feedback
- Response time under 10 ms, frequency response above 100 Hz (–3 dB and –90° phase)
- Hysteresis less than 0.2 per cent, threshold less than 0.1 per cent, zero-point offset less than 1 per cent

- Power consumption less than 5 W, supply voltage 22–30 V DC
- Dirt-shear force in excess of 400 N – high resistance to contamination
- Vibration resistance: 30 g (all axes); shock resistance: 50 g
- Choice of two seal materials: nitrile, Viton
- ISO 4401-03-02 mounting interface, secured with M5 × 55 mm screws, tightening torque 7.5 Nm

| Position | Description | Options |
|---|---|---|
| [1] | Nominal flow rate | 5 to 40 l/min (any value, rated at 35 bar ΔP per control edge; 40 l/min only in the Axis version) – suffix R for reversed A/B connections (e.g. 40R) |
| [2] | Flow behaviour | A – Axis (1 % overrange, linear characteristic) B – Float Centre (5 % overrange P, 5 % underrange T, deadband characteristic) D – Blocked (5% overlap, deadband characteristic: no flow between ±10% of setpoint) O – Overlap (3% overlap, gradual characteristic with reduced gain in the zero range) X – Special version on request Alternative characteristics available via a second letter (e.g. AD = Axis with deadband characteristic) |
| [3] | Control signal | A – ±10 V | B – ±20 mA | C – 4–20 mA | D – ±5 V | E – ±5 mA | F – ±10 mA | X – Special Combined input/output possible (e.g. AC = ±10 V input, 4–20 mA output) |
| [4] | Power-off position | B – Float (P blocked, A, B and T connected) C – Passive (the spool returns passively to the centre position under typical flow conditions) D – Blocked (all ports blocked) PA – A pre-set (P connected to A, B connected to T) PB – B pre-set (P connected to B, A connected to T) X – Special version on request This position is assumed in the event of a power failure, fault or when the enable input is deactivated. |
| [5] | Electrical connector | E – 6+PE circular connector, EN 175201-804 / MIL 5015, housing size 14 E4 – 4-pin circular connector, EN 175201-804 / MIL 5015, housing size 14 X – Special design available on request |
| [6] | Enable function | N – No enable function Y – Enable mode via voltage input (Drive ON: 9–30 V / Drive OFF: 0–5 V; only with connector E) |
| [7] | Hydraulic fluid | R – Hydraulic oil in accordance with DIN 51524, filtered to ISO 4406 18/16/13 (water-free synthetic fluids available on request) X – Special version available on request |
| [8] | Sealing material | N – Nitrile NBR (Shore 90) – standard for mineral oils V – Viton FKM (Shore 85) – increased resistance to high temperatures and chemicals X – Special version available on request |
