Applications for our electro-hydraulic control devices
Power amplifiers
Power amplifiers control proportional valves by regulating the valve coil's mechanical energy in accordance with the control signal. This is how they achieve the desired function in the hydraulic circuit. They combine electric control with hydraulic power transmission, enabling simple and efficient control of movements and forces. Power amplifiers are used where proportional valves are required, e.g. in industry, mechanical engineering or automation technology. By integrating sensors into control systems, power amplifiers can also be used in complex systems.
Pressure controllers
Pressure controllers automatically control the pressure in a hydraulic system. They combine electric control with hydraulic technology to precisely maintain the desired pressure. The controller receives information about the current pressure in the system from a pressure sensor and adjusts the valve position accordingly to avoid fluctuations and keep the pressure at the desired level. This is particularly important in applications where precise pressure adjustment is required, such as in manufacturing, mechanical engineering or hydraulic drive systems. By using sensors and electro-hydraulic actuators, pressure controllers enable high accuracy and response speeds, which contributes to improving the entire system's efficiency.
Position controllers
Position controllers precisely control the position of a hydraulic cylinder. They combine electric control with hydraulic drive technology to precisely control the movement of an object or machine. The position controller receives information about the cylinder's current position, often from sensors such as encoders or potentiometers, and compares this with the desired target position. Based on this feedback, the controller adjusts the actuation of the valve to control the movement and achieve the desired position quickly and accurately. This technology is often used in applications where precise movements are required, such as in automation technology, robotics, mechanical engineering and manufacturing. Position controllers enable high accuracy, flexibility and efficiency in hydraulic systems.
Synchronisation controllers
Synchronisation controllers are used in control technology to synchronise the movements or positions of several hydraulic cylinders independently of external interference. In practice, these types of controllers are often used in applications where several hydraulic cylinders or motors have to be operated simultaneously to ensure that they work in a uniform manner and synchronously. This is particularly important in mechanical engineering, automation technology and in the aerospace industry, where synchronised movements are required.
