Tokyo KEIKI TOKIMEC Solenoid operated directional control valves
DG4V-3 Models: DG4V-3-2A DG4V-3-2N DG4V-3-2C DG4V-3-6C DG4V-3-8C DG4V-5
Max. Working Pressure: 35MPa Allowable Tank Port Back Pressure : 20. 6MPa Power Consumption: DC 28-31W AC: 19-26W Insulation Class: H 180℃ Curent values and power consumption varies with temperature
conditions. Values shown in table are based on 30°C. In the AC/DC conversion type, AC power is used to activate the DC
solenoid by the built-in rectifier, and it comes with the
characteristics featured bv pc solenoids, This means that the items
aiven for the pe solenoids aooly for the maximum flow . Consult Tokyo Keiki for details on solenoids for the supply
voltages which are not listed above. Mounting orientation To ensure sure switching of no spring detented type valves, mount valves so spool axis is horizontal. There are no mounting attitude restrictions for other spool/spring arrangements. Solenoid energization Always ensure that one side of solenoid is deenergized before energizing the opposite side. For spring centered and spring offset valves, solenoid should be continuously energized during circuit switching. Deenergization of solenoid will cause spool to return to prescribed position by spring force. For no spring detented type valves, spool will be maintained in switched position by the detent but to ensure sure circuit switching, solenoid should be energized for more than 0.1 second. T(tank)port piping Prevent abnormal pressure surges above the allowable back pressure rating from being generated in T port. Valve is wet armature type so ensure that valve is always filled with oil. Using valves as two-way and three-way Valve is designed as four-way and max. flow is limited when using as two or three-way valves. Consult Tokyo Keiki for details. Long periods of solenoid energization Care should be paid as long periods of solenoid energization at high pressure may cause spool sticking and switching malfunction. Malfunctions due to surge pressure Avoid combining flows of tank lines prone to surge pressures. Surge pressures in T port may lead to spool malfunctions. No spring detented type valves are susceptible to such malfunctions during deenergization. Manual operation For manual switching, push the manual override pin. Be aware that actuation force increases with higher back pressure.
