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 300g 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. The S4 Pro is suited to sub actuator control systems where spool positioning needs to be achieved without supply pressure.
* Based on a S6 Pro Valve which will save 17 tonnes of Carbon Dioxide over 15 years.
