Servoventiler

Servoventiler, also known as servo valves, are a type of hydraulic valve that uses an electrical control signal to precisely regulate fluid flow. They are essentially closed-loop systems where a pilot valve, often a proportional solenoid valve or a smaller servo valve itself, controls the main valve spool. Sensors within the valve monitor the spool's position, and a control system compares this position to the desired position dictated by the input electrical signal. Any deviation triggers an adjustment by the pilot valve, moving the spool until the desired flow rate or pressure is achieved.

The primary advantage of servoventiler is their high accuracy and rapid response time. This allows for very precise control of hydraulic actuators in applications requiring dynamic movement and exact positioning. They are used in a wide range of industries, including aerospace for flight control systems, industrial automation for robotics and machine tools, and mobile hydraulics for sophisticated equipment like cranes and excavators.

Servoventiler can be designed to control flow rate, pressure, or both. They are typically more expensive and complex than simpler directional or proportional valves due to their integrated feedback mechanisms and sophisticated control electronics. However, for applications where precise and dynamic hydraulic control is paramount, servoventiler offer a superior solution.
