It is the most efficient direct drive valve for high flow applications in pressing, power generation, and large testing rigs. 

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.

Unlock massive energy savings with the Domin S10 Pro series. 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.

We also offer models with lower and higher flow rate capabilities. The S6 Pro, our most popular model, has higher performance capabilities of <3.5ms response rate and a flow range of 1.6 to 15.9 gpm (6 to 60 lpm). Our S12 Pro uses the S6 Pro as it’s first stage to achieve flow rates of up to 153 gpm (580 lpm). The P10 Pro has less dynamic performance, but is more cost-effective for applications that do not need an ultra-fast response rate.

* 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.

* 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.

** The valve supply must be protected with a 4 AT fuse or equivalent overcurrent protection device.

*** Valves with a current command signal use a 0.1% tolerance shunt resistor to measure demand current.

**** For 4 to 20mA command signal, a current in this range will disable the motor drive until a current outside this range is received at the command input.
