The Efficient Upgrade to Pro Performance
We have evaluated the Domin S6 Pro X and have been impressed with the low phase shift, response time, and Domin’s customer support. We are looking forward to working on more opportunities in the field.

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 seamless upgrade for Bosch, Moog, Parker, and Woodward. We now stock several valves for a wide range of applications. Saving money with better performance.

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.

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.

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.
