An electric pinch valve operates by constricting a flexible tube or hose, which is typically made of rubber, elastomer, or other flexible materials. The valve body is usually constructed from durable materials like stainless steel or plastic, housing a flexible tube that serves as the flow channel. The core of the electric pinch valve’s operation involves an electric actuator, which provides precise control over the valve's opening and closing mechanism.

    When the valve is actuated, the electric actuator applies force to a pinch mechanism that squeezes the flexible tube, thereby restricting or completely stopping the flow of the material within the pipeline. By adjusting the actuator, the operator can control the degree to which the tube is pinched, allowing for fine-tuned flow regulation. This method of flow control is particularly useful when handling materials that are abrasive, viscous, or hazardous, as the pinch mechanism prevents direct contact between the fluid and the valve components.
