DG3V-10 11 Design Remote pilot operated directional valves
The Eaton size 10 Directional Control Valve serves as a control valve package. This package is generally used to control large flows, to 1100 l/ min (290 USgpm). Each valve contains a mainstage spool which is positioned by one of three arrangements:
Spring offset - For single stage operation, one spring returns the spool to an offset position. For two– stage operation, the spring and washer are removed from the main stage and offset action is obtained from the pilot valve.
Spring centered - The spring and washer are located on both ends of the main stage spool to control centering.
Detented - Spool position is determined by a detent in the pilot valve. Should pilot pressure be lost, the main stage spool will spring to center.
Features and Benefits
The size 10 Directional Valve is designed and manufactured by Eaton, which has over 70 years of experience as the global leader in fluid power and motion control.
Endurance tested to 10 million cycles and fatigue tested to NFPA specifications without failure to ensure the highest reliability in applications requiring high flows and pressure.
This control valve package offers a wide variety of spools and spring, pilot choke adjustments, integral check valves and port orifices to meet most system requirements. High force solenoids and centering springs assure consistent shifting through a wide range of pressure and silting extremes.
Electrical options including coil types, connections, and wiring housings allow full compatibility and reliable performance in any system application.
Plain, waterproof, and lockable manual override options are available to facilitate system troubleshooting or servicing.The DG5V models are functionally interchangeable with previous size 10 design valves. Should size constraints prevent physical interchangeability (along length axis), an EN503 option is available.
