Automatic Engine Overspeed Shutdown Valve

Our range of spring-loaded poppet valves are specifically engineered to automatically halt engine operation by closing the air intake when excessive over speeding is detected. These valves are customizable to fit nearly all popular engine ratings and air intake pipe sizes. The closing mechanism of these valves relies on the intake airflow. As the airflow increases, it generates a closing force on the valve. This force is counteracted by an adjustable valve spring. When the airflow reaches a certain threshold, it overcomes the spring resistance, causing the valve to shut. Once the valve has closed, it remains in this position until the engine comes to a complete stop. These valves are suitable for both naturally aspirated and turbocharged engines. However, it should be noted that in turbocharged engines, the actual shutdown speed may vary slightly more compared to naturally aspirated engines. Nevertheless, the valves still ensure adequate protection against over speeding and potential damage, except in cases where an exact repeatable shutdown speed is necessary.
