What are electro-hydraulic control valves?
Electro-hydraulic control valves experienced a long-time development from a pure mechanical structure to mechatronics hydraulics integration. In addition, electro-hydraulic control valves are currently being integrated with digital technology and a variety of communication technologies.
How do I choose the right electrohydraulic valve?
To choose the proper electrohydraulic valve for a specific application, designers must consider specific application and system configurations. Supply pressure, fluid type, system force requirements, valve dynamic response, and load resonant frequency are examples of the various factors affecting system operation.
Are electro-hydraulic control valves ready for Industry 4.0?
In addition, electro-hydraulic control valves are currently being integrated with digital technology and a variety of communication technologies. Since Industry 4.0 is an ongoing revolution, electro-hydraulic control valves should show its vitality with new technology.
What is an electrohydraulic servo valve (EHSV)?
An electrohydraulic servo valve ( EHSV) is an electrically-operated valve that controls how hydraulic fluid is sent to an actuator. Servo valves are often used to control powerful hydraulic cylinders with a very small electrical signal.
Electronic Controllers from Analog to Digital
Electro-hydraulic control valves typically have electronic mechanical converters and feedback signal transduces, which represents the output and input. In the 1970s, electrohydraulic control valves began to adopt electrical transducers, like hall-effect position transducers [20]. Furthermore, for a control system, the processing unit is essential t
Actuators of Electro-Hydraulic Control Valves
For hydraulic systems, the electro-hydraulic control valve is a signal conversion and power amplifying component [26], and its power amplification factor reaches 104–106 with a fast response speed. In 1946, Tinsley of the United Kingdom applied for a patent for a two-stage electro-hydraulic control servo valve, whose pilot stage of the servo valve
Control Strategies and Novel Concept Valves
3.3.1 Control Strategies on Traditional Valves Electro-hydraulic control valves used to feature proportional-integral-derivative (PID) controllers; however, many model-based controllers are being developed due to digital technology, which makes an important contribution to Industry 4.0. Because of the PID controller’s effectiveness and practicability, it is widely used in electro-hydraulic control valves until now [48, 49]. In addition, there are also many improvement methods based on PID controllers. Han et al. [35] implemented a fuzzy-b
