Electric valves in power hydraulics

What is an electro-hydraulic control valve

An electro-hydraulic control valve is a key element of power hydraulic systems, allowing for oil flow direction control via an electric signal. Unlike manual valves, control is performed through electromagnetic coils, which allows for precise, fast, and remote management of the operation of actuators and hydraulic motors. Electro-hydraulic control valves are used wherever automatic or semi-automatic movement control of actuators in a hydraulic system is required.

Application of electro-hydraulic control valves

An electro-hydraulic control valve is used, among others, in:

• industrial machinery,

• agricultural and municipal machinery,

• mobile hydraulic systems,

• production lines,

• industrial automation installations.

Thanks to electric control, it is possible to integrate the valve with sensors, PLC controllers, and automation systems, which significantly increases the functionality of the entire system.

12V and 24V electro-hydraulic control valve – how to choose

The Hydron range includes electro-hydraulic control valves 12V and 24V, allowing the component to be matched to installations powered in both vehicles and stationary machines. Choosing the correct coil voltage is crucial for the correct and safe operation of the valve. When choosing an electro-hydraulic valve, one should consider:

• supply voltage,

• number of sections,

• nominal flow,

• working pressure,

• mounting method.

Design and principle of operation of electric valves

Electro-hydraulic control valves consist of a hydraulic body and electromagnetic coils, which change the position of the spool when voltage is applied. This design allows for fast switching of oil flow direction and precise control of actuator movement. This solution eliminates the need for manual operation and allows for full automation of the hydraulic system.

Parts and accessories from the HYDRON range

In installations where an electro-hydraulic control valveis used, supplementary elements responsible for correct control and safe operation of the system also play an important role. The most commonly used include electromagnetic coils, which are responsible for controlling the operation of the valve spool and must be selected for the correct supply voltage, usually 12V or 24V. Essential components also include power supplies and electrical accessories, ensuring stable and safe power supply to the coils in stationary and industrial systems. In assembly and service practice, electro-hydraulic valves very often work together with hydraulic quick couplers, which allow for efficient connection and disconnection of lines without oil leakage. Proper selection of all these elements allows for building a complete, reliable power hydraulic system adapted to work in demanding conditions.
