Tokyo Keiki Drectional Valves
Solenoid operated directional control valves DG4V-3
Wet type solenoid valve boasts superior valve life with low switching noise. No seals on sliding surfaces eliminates leakage worries.
Many valve options including 3 types of wiring connections, indicator lamp, surge suppressor, and AC/DC rectifier.

12 Design no.
Current 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 by DC solenoids. This means that the items given for the DC solenoids apply for the maximum flow.
