Electric pinch valves operate on a straightforward yet effective principle. At the heart of the system is a flexible tube or hose, which is the key component that controls the flow of the medium. The tube is typically made of rubber or other elastomeric materials, allowing it to deform easily. The pinch valve itself consists of a mechanism that compresses the tube to restrict or stop the flow of the medium.

    The electric component of the pinch valve involves an actuator, usually a stepper motor or a solenoid, which is controlled electrically. When an electric signal is sent to the actuator, it applies pressure to the pinch mechanism, causing the tube to collapse and thus controlling the flow rate. The electric control provides precise and repeatable adjustments, which is crucial for maintaining consistent operational conditions in various applications.
