DG5V-8-S-R-9C-T-S-M-FW-G-10-EN571

The DG5V-8-S-R-9C-T-S-M-FW-G-10-EN571 directional valve is built by Vickers within the DG5 Two-Stage Directional Valves series. It directs hydraulic flow to actuators in automated systems. An ISO 4401-08 (NFPA D08) mounting interface allows direct manifold installation and reduces external piping. A CETOP 3 pilot valve supplies the control stage that shifts the main spool consistently across common industrial platforms. Spool type 9 opens passages to tank over tapered lands to soften flow transitions and limit shock. The spring-centered C arrangement returns the spool to neutral when pilot pressure is removed, restoring hydraulic isolation automatically. An R-option reducer module lowers pilot pressure to match sensitive loads without extra components. Internal pilot drain T routes pilot oil to tank without a separate drain line. A 5.20 bar pressure-port check valve secures upstream pressure against reverse flow during transient conditions. Design number 10 identifies the current engineering revision so spare parts and seal kits remain compatible with this build.

A 12 VDC G-coded coil energizes the solenoid so the valve can be driven from low-voltage mobile controllers. The coil draws 30 W, balancing force output with modest electrical demand for battery-powered equipment. Flying lead style F wiring simplifies field replacement because connection does not rely on fixed terminals. Continuous duty rating ED 100 % allows the coil to remain energized without time limits, supporting long holding periods in process machinery. Gauge ports marked M under ISO 6149 provide threaded test points for safe pressure monitoring during commissioning. The enclosure meets IP65 with the correct plug and housing, keeping dust and water jets away from the electrical parts in outdoor installations. A 1/2 NPT W wiring housing offers a standard conduit entry that protects leads from mechanical damage and meets North American wiring practice.
