Contact us for current availability
View all specifications

The Domin S6 Pro is a NG06 (CETOP 03) 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.

As well as this, the S6 Pro Servo valve offers valuable upgrades over it's competitors- notably 65% Faster Step response than the Atos DLHZO, 50% Higher Flow than the Bosch Rexroth 4WRPEH 6 and is also 78% Lighter than the Moog D633.

The Domin S6 Pro valve also underwent extensive testing at the hands of Delta Motion, providing exceptional results in key areas.
