Specifications
Solenoid Specifications
• 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.• Consult Tokyo Keiki for details on solenoids for the supply voltages which are not listed above.

Spool Configuration Diagram Functions and Applications
At the neutral position the pump is set to the unload status and the actuator to the floating status.In the case of the 2-position type, all the ports are connected to the tank during the course of switching so shock is reduced.
The valve is used when, at the neutral position, the pump is to be set to the unload status and the pressure oil is to be sent only in one direction, and the actuator is to be kept shut down.
At the neutral position the pump pressure is maintained, and the actuator is locked.It must be borne in mind that all the ports are blocked during the course of switching so shock will be generated in the case of the 2-position type.
Slight movements in one direction of the actuator caused by leaks from the P port at the neutral position are prevented.
At the neutral position the pump pressure is maintained, and the actuator is set to the floating status.As is the case with spool type “2,” the 2-position type is used when the pump pressure is to be maintained even during the course of switching. Shocks arise during the course of switching as well, but the shocks are less compared with spool type “2.”
At the neutral position a differential circuit can be configured.
At the neutral position the pump is set to the unload status, and the actuator is locked.A multiple number of the valves can be connected in series for use.
This type, which is a modified version of spool type “6,” was created by adding restrictors between the A → T and B → T ports.The restrictors serve as brakes so when the actuator is to be shut down, it can be shut down faster than is the case with spool type “6.”

Notes on Operation ● 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. (See graph)
● Solenoid indicator lamp For valves with indicator lamps, the lamps will light when current flows to the solenoid. ● Electrical wiring Solenoid and conduit box are pre-wired. Refer to below diagrams for wiring from power source to conduit box and DIN connectors.
Mounting Bolts (JIS B 1176, Strength Class 12.9)
● Mounting bolts must be ordered separately. ● Tightening torque of mounting bolts: 7 to 8 N•m
Subplate
● Subplate and bolts must be ordered separately. ● See page R6-6 for dimensions. ● See page R6-6 for plural mount subplates. ● Max. working pressure is 21 MPa. For higher pressures, valve should be mounted on manifold block.
