Our Products
S4 Pro
Rated Flow (0.5-18 l/min)

The S4 Pro valves are lightweight, high-performance directional flow control valves. Suited to applications requiring superior performance, dynamics and reliability expected of a proportional valve in an ultra-compact package.
S6 Pro-min
Rated Flow (18-60 l/min)

The Domin S6 Pro servo proportional valve has been designed to achieve the best characteristics from two competing valve technologies: fluid amplified electrohydraulic valves and proportional valves.
S6 Pro X-min

S6 Pro X

Rated Flow (10-63 l/min)

The Domin S6 Pro X servo proportional valve builds upon the benefits of the S6 Pro. Notably, the S6 Pro X is available in two versions: voltage-controlled and current-controlled, providing greater flexibility in its application.

S10 Pro

Rated Flow (50-250 l/min)

The Domin S10 Pro is a single-stage servo proportional valve which combines high flow, excellent dynamics, strong chip shear, and low power consumption. The S10 Pro has been designed to sustain high bandwidth operation at exceptional flows without significant limitation of operating pressures or duty cycles.

S4 Pro Servo Proportional Valve

The Domin S4 Pro series of servo proportional valves are lightweight, high-performance directional flow control valves that cover a range of rated flows from 0.7 l/min to 18 l/min up to a maximum pressure of 350 bar per spool land.

Based on a miniature port circle of 12.2 mm and with a weight of less than 300g, the S4 Pro is suited to applications requiring superior performance, dynamics and reliability expected of a proportional valve in an ultra-compact package.

S6 Pro Servo Proportional Valve

The Domin S6 Pro servo proportional valve has been designed to achieve the best characteristics from two competing valve technologies: fluid amplified electrohydraulic valves and proportional valves.

The S6 Pro has the size, mass, and dynamic capabilities of the most compact electrohydraulic valves, and the low quiescent leakage and reliability of the best proportional valves.

S6 Pro X Servo Proportional Valve​

The Domin S6 Pro X servo proportional valve builds upon the benefits of the S6 Pro.

Notably, the S6 Pro X is available in two versions: voltage-controlled and current-controlled, providing greater flexibility in its application.

Based on the S04 port pattern and weighing less than 800 g, the valve has a rated flow of 63 litres per minute. It offers unparalleled performance for a variety of demanding applications.

The Domin S10 Pro is a single-stage servo proportional valve which combines high flow, excellent dynamics, strong chip shear, and low power consumption.

The S10 Pro has been designed to sustain high bandwidth operation at exceptional flows without significant limitation of operating pressures or duty cycles.

Where servo proportional valves have been employed to control high flows there is a clear trade with packaging size and weight. The S10 Pro valve is packaged to be lower weight and more compact than the best of electrohydraulic servo valves.

Domin’s Valves Deliver

Increased Reliability, Performance & Profitability

Set new standards in power density and dynamic performance and without compromise to cost, efficiency and reliability available at competitive market prices.

More Efficiency

Up by 95% efficiency through regenerated energy use, saving $400 per valve per year.

More Power

With a more powerful motor, the high torque electric motor gives great resistance to chip shear events.

More Precision

Advanced electronics give precise and accurate closed-loop control and modern spool sensing technology.

More Productivity

Fast steps responses of 3ms compared with competitors of over 8ms, high flow rates, and high frequency response.

More Control

Low hysteresis that give high accurate movement in both directions, low threshold, and low null shift.

More Reliability

Lower servicing costs, as there are no high-pressure seals, no filters, fewer components, simpler assembly, and environmental sealing.

More Performance

With no first stage, all small blockage prone features are removed.

More Flexibility

Easy to interchange these units with affordable assembly kits available to minimise system changes. These include female connectors and adaptor plates.

Domin Report

The Next Generation of Servo Valves

Read the latest Domin report on next generation Servo Valves. Technological advancement is happening at lightning speed and driving radical change. Applying modern technology to the hydraulics industry could start a revolution.  

Saving money with better performance
We’ve been waiting a long time for an extremely rugged servo valve that holds up in the forest industry. We didn’t expect this valve to be so cost-effective and handle extreme vibration at high cycle rates. With a very small footprint and as a drop-in replacement for Bosch, Moog, Parker, and Woodward. We now stock several valves for a wide range of applications. Saving money with better performance.
Sales Manager, Peerless Engineering
Much better than the Moog D633.
The valve was within specs (in terms of pressure drop and response time) and was much better than the Moog D633. This is very good news for the future tests we will be performing.
Head of R&D, PYTHEAS Technology
The valve performance & durability is unmatched.
Domin’s customer service is the only thing that outshines the performance of the valves. The valve’s performance, configurability & durability is simply unmatched. We’ve been able to replace several OEMS valves with a single Domin valve. We’ve put the Domin into our harshest applications & it performed flawlessly.
Vice President, The Servo Group
Best servo valve we have ever seen!
The Domin S6 Pro servo valve is the best servo valve we have ever seen. It has an incredible response time and is unbelievably tiny.
Technical Manager, Careful Hydraulics and Electronics
Extremely responsive, small size, and looks great!
The Domin S6 Pro performs just as you advertised it to be. Extremely responsive, small in size, and looks great!
Fluid Product Services Manager, Automation & Control Technologies
It has great hysteresis and good repeatability.
“The valve is well made, solid, looks great and has a nice finish. It has great hysteresis and good repeatability. We tested it thoroughly and were unable to find any faults.”
Technical Manager, Magneto Hydraulique and Pneumatique Inc
