(note1)Operating pressure may be limited by maximum RPM depending on the motor output

(note2)This is the theoretical flow under no load. The actual flow will vary depending on the load pressure.

(note3)Rated pressure is (available) pressure at the rated torque of the motor, and maximum operating pressure is pressure output at 150% torque. However, if this pressure exceeds 30MPa, the maximum operating pressure of the hydraulic unit is limited to below 30MPa.

(note4)An auxiliary tank can be connected if fluctuation in oil volume is greater than allowed values. Contact us for information.

(note5)An oil tank will be separately necessary. Our company can make the oil tanks so contact us for information if you need one.

(note6)Operating conditions may limit the maximum RPM and operating pressure to values lower than those shown in the table above, contact us for more information.
Contact us about operations in which pressure is continuously added over a long period of time because the temperature of the hydraulic fluid sometimes rises due to the operating pressure, so restrictions on the operating pressure and the additional installation of a refrigeration system may be necessary.

(note7)The operating hydraulic fluid temperature is affected by a variety of factors such as the hydraulic unit installation environment, operational method, load condition, etc. so be sure to confirm with your customer in a situation in which the production machine is operating.
In the case that the hydraulic fluid temperature exceeds the operational hydraulic fluid temperature range, it will be necessary to additionally install a separate refrigeration system, so contact us for information.

Measurement

 

Features

It is a solenoid valve that monitors the direction switch position of the valve and possesses the function of outputting a signal.
It operates the switch directly with the valve operation so reliable output can be obtained.
It does not use magnetic sensors or proximity sensors so the temperature drift and hysteresis are smaller than before.

Specifications

(Note 1) The maximum flow differs depending on the valve format and working pressure.

Working principle

When the spool is in a neutral state, the fixed points of contact and the moving points of contact touch and are in a state of electrical conductance. When the spool begins to operate, the moving points of contact move to the left side in tandem with it, and the fixed points of contact and moving points of contact enter a state of electrical non-conductance.
