The Domin S4 Pro

PRODUCT OVERVIEW

S4 Pro

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 0.5 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.

Servo Proportional Valve

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.
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.
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.
