DG5V-10 10 Design Solenoid Controlled Pilot Operated Directional Valve
The Size 10 Directional Control Valve serves as a control valve package. It offers directional control, pilot pressure reducers, pilot chokes, and main stage stroke adjustment to control the flow. The valves are generally used to control large flows up to 700 l/min (185 USgpm) at 350 bar (5000 psi) and provide low pressure drops. The range includes:
DG3V-10 - remote pilot operated valve.
DG5V10 - DG4V-5 D05 pilot valve 210 bar (3000 psi) tank line rating.
Each valve contains a mainstage spool which is positioned in the valve by special arrangement. The four arrangements are:
Spring offset - For single stage operation, one spring returns spool to an offset position. For two–stage operation, springs and washers are removed from main stage and offset action is obtained from pilot valve.
Spring centered - Spring and washer are located on both ends of main stage spool to control centering.
Pressure centered - Centering springs are used in addition to pilot pressure, to provide positive centering should pilot pressure fail.
No spring for DG3 - Springs and washers are provided so that in the event of pilot pressure failure, the main spool will spring center.
