DG4VS-3 Series - Shockless solenoid operated directional control valves - DG4VS-3-6C-M-P9-VR-7-56

Mounting orientation: No restrictions on valve mounting attitude.

Solenoid energization: Always insure that one side solenoid is deenergized before energizing the opposite side solenoid. 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.

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 insure that valve is always filled with oil.

Using valves as two-way and three-way: Valve is designed as four-way and as such max. flow is limited when using as two or three-way valves. Consult TOKIMEC 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 valve T port may lead to spool malfunctions.

Manual operation: For manual switching, push the manual override pin. Be aware that actuation force increases with higher back pressure. (See graph)

Solenoid indicator lamp: For valves with indicator lamps, the lamps will light when current flows to the solenoid.

Conduit box wiring: Solenoid and conduit box are pre-wired. Refer to below diagram.
