Control options: 6 options including pressure compensation control

Various control options enable circuit simplification and energy saving.

Control system Symbol Features Characteristics
Pressure
compensation
type (manual)
N Discharge amount automatically decreases to maintain the set pressure when discharge pressure reaches the value specified in the compensator. Pressure compensation type (manual/remote control)
Pressure
compensation
type
(remote control)
P Provides the same features as those for the manual system. Discharge pressure can be remotely controlled with an external pilot pressure.
2-pressure,
2-flow control
type
NQ Discharge pressure can change by two levels through the sequence valve embedded in the pump; therefore, one unit can perform conventional high/low pressure control and circuit energy can be saved. 2-pressure, 2-flow control type
Solenoid cutoff
control type
RS Solenoid valve for unloading is mounted on the pressure compensation type model, with the aim of minimizing energy loss when hydraulic pressure is not necessary. Solenoid cutoff control type
2-pressure
control type
WS Two types of pressure compensation are obtained by turning on/off the solenoid valve embedded in the pump. The two kinds of output can be controlled while maintaining a constant actuator speed. 2-pressure control type
2-pressure,
2-flow control
type with
solenoid cutoff
RQS Unload function is added to the 2-pressure, 2-flow control type, to enable unloading with the solenoid valve embedded in the pump when hydraulic pressure is not necessary. 2-pressure, 2-flow control type with solenoid cutoff
2-cutoff control
type
CS Two kinds of pressure and flow characteristics can be obtained with the solenoid valve embedded in the pump and the discharge control mechanism. 2-cutoff control type
