These EH Series are compound products of hydraulic equipment using the latest electronic and sensor technology based on the reputable E Series proportional electro hydraulics controls. We have realzed epochmaking easily usable hydraulic equipment with high precision and reliability by unifying amplifier ,sensor,digital data indicator which are required for proportional or servo control system into valves, and making them compact.
•Just preparing the power source (DC) for controls and command signals in addition to
hydraulic source you can easily structure proportional control system or servo system.
Amplifiers exclusively used for the system or electric control panels separately
installed are neccesary.
•By using built-in sensors:
1) Pressure,orifice opennes which can be converted to flow raie can he detected and
(2) As well as a compound amplifier, closed loop system can be structured.
(3) sensor output signals or deviation signals at structuring closed loop system can be
•Such disadvantages as seen in ordinary hydraulic systems in which hydraulic
conmponents. sensors and amplifiers are interconnected with each other but Installed
separately are eliminated.
