HYDRAULIC SERVO VALVES – S10 PRO

Hydraulic Servo Valves – S10 Pro

Unrivaled Performance and Efficiency

Unlock massive energy savings with the Domin S10 Pro series, the most efficient direct drive valve for flows ranging from 13 to 66 gpm (50 to 250 lpm).

Designed to sustain high bandwidth operation at exceptional flows without compromising on operating pressures or duty cycles, the S10 Pro is the pinnacle of reliability and versatility. Where other servo proportional valves struggle with packaging size and weight, the S10 Pro rises above, offering a lighter and more compact alternative to traditional electrohydraulic servo valves.

Experience the difference with the Domin S10 Pro. Whether you’re dealing with high flows or demanding applications, its single-stage design ensures optimal performance every time.

Available on NG10 port pattern as standard. S77 adaptors available.

Enable Function

Valves can be provided with an enable function. This allows the valve to be enabled or disabled by varying the voltage into the enable pin. Note that valves with code C command type can also be enabled or disabled using the command signal; see the corresponding table for further details.

Normal Operating Conditions		Min.	Typ.	Max.
Voltage for Drive Enable*	V	9	–	60
Voltage for Drive Disable	V	0	–	2
Input Impedance	Ω	50	–	–

* The enable pin is pulled up to Supply + within the valve via 30k. The enable pin may be left floating to enable the valve.

* Conditions outside of the absolute maximum ratings may cause permanent damage to the valve. Operation of the product outside of the nominal operating conditions is not guaranteed and may affect product reliability.

** Maximum current draw occurs during chip shear events or operation at high frequencies (e.g. Close to 3dB frequency) and at maximum rated flow. Typical operating conditions require significantly less current.

*** Current inputs use a 0.1% tolerance shunt resistor to measure demand current.

**** The value of the shunt resistor to measure output current should not exceed stated maximum value.

***** A current in this range will disable the motor drive until a current outside this range is received at the command input.
