EH Series Proportional Electro-Hydraulic Valves

The EH Series on-board electronic proportional controls are compound electro-hydraulic products which merge the latest electronic and sensor technology with Yuken’s reputable E Series proportional controls. Yuken has realized an industry leading position by creating compact hydraulic equipment that features high precision and reliability by unifying the amplifier, and sensor, all of which are required for proportional or servo control systems.

Proportional control systems or servo systems can be easily structured by simply preparing the power source (DC) for controls and command signals along with the hydraulic source.

Amplifiers exclusively used for the system or separately installed control panels are unnecessary.
By using built-in sensors;
(1) pressure and orifice openness, which can be converted to flow rate, can be
detected and controlled remotely.
(2) along with a compound amplifier, a closed loop system can be structured. (3)sensor output signals or deviation signals at structuring closed loop system
can be monitored.

Disadvantages seen in ordinary hydraulic systems in which hydraulic
components, sensors and amplifiers are interconnected with each other but installed separately are eliminated.
