S4 Pro Direct Drive Servo Valve

The Domin S4 Pro Direct Drive Servo Valve (DDV) represents a revolution in servo valve performance. Up to now, the customer has been left with an uncomfortable choice between the large footprint and weight of a DDV and the pressure and reliability limitations of EHSVs. The compromise is particularly acute with low flow applications.

The S4 Pro is based around the miniature 12.2 mm port circle and weighs less than 300 g with spool feedback for a rated 18 lpm. It delivers all the performance you would expect from a high-performance EHSV but is able to deliver it without the parasitic flow and pressure demands of a two-stage servo valve.
