Seat hydraulic directional control valve D660 series

pilot-operatedfor high flow rates

The Moog D66x series valves are pilot operated proportional valves with integrated electronics and analog interface The D66x proportional valves have spools that are fitted directly in the valve housing and are hydraulically pilot-operated. This design allows for much higher flows and enables for various different failsafe options. The D66x series uses the familiar ServoJet as the pilot. This pilot is characterized by a low but constant need for pilot oil. Valves of this series are available as two stage and three stage configuration covering sizes 05, 07, 08 and 10. This proportional valve was developed with demanding industrial applications in mind and is characterized by high functional flexibility and outstanding dynamics • Optimized design of valve bodies for high rated flow • Available as 2- or 3-stage valves, dependent on required dynamics • Optional ServoJet or nozzle-flapper pilot valves • Excellent dynamic response due to improved pilot stages • Different fail-safe options available allowing the best fit to the application
