Understanding Engine Overspeed:
Engine overspeed occurs when the engine exceeds its designated operating speed limit, typically due to a malfunction in the fuel system, turbocharger issues, or load changes. This phenomenon can lead to catastrophic engine failure, endangering both the machinery and surrounding personnel. The automatic engine overspeed shutdown valve is designed to prevent this from happening by halting the air intake, effectively stopping the engine when it reaches a critical speed threshold.
Key Features of the BET Bold Overspeed Shutdown Valve:
Spring-Loaded Poppet Valve Mechanism: The BET Bold valve features a spring-loaded poppet mechanism that responds to increased airflow as engine speed rises. When the engine reaches a pre-set overspeed threshold, the valve closes the air intake, causing the engine to stop. This system ensures immediate protection, reducing the risk of engine damage due to overspeeding.
Customizable Fit for All Engine Sizes: Our valves are designed to fit various engine ratings and air intake pipe sizes. Whether your engine is naturally aspirated or turbocharged, the BET Bold valve can be calibrated and customized to meet your specific needs. This flexibility makes it a versatile solution for numerous applications across different industries.
High Reliability for Turbocharged and Naturally Aspirated Engines: The BET Bold valve is suitable for both turbocharged and naturally aspirated engines. While the shutdown speed may vary slightly for turbocharged engines, the valve still provides exceptional protection against overspeeding, ensuring the safety of your operations.
Compact and Durable Design: Our valves are designed with space efficiency and durability in mind. The compact size allows for easy installation even in tight engine compartments, and the robust construction ensures long-lasting performance in harsh environments.
Safety and Compliance: Safety is at the forefront of our design philosophy. The BET Bold valve complies with strict international standards, including ATEX certification. This ensures that our valves meet the highest safety and performance requirements, making them ideal for use in potentially explosive atmospheres or hazardous environments.

Installation Guidelines:
The BET Bold valve is designed to be installed as close to the engine’s air intake manifold as possible. For turbocharged engines, the valve should be positioned upstream of the turbocharger or, if the outlet temperature exceeds 150°C, downstream of the intercooler.
When multiple intake pipes are present, a balance pipe arrangement may be required. This ensures even air distribution and prevents excessive pressure on individual intake pipes.
Maintenance and Calibration:
Proper maintenance and calibration are crucial for the BET Bold valve’s continued performance. Routine inspections should be performed every three months to ensure that the valve remains clean and operates smoothly. During calibration, the engine’s speed is gradually increased until the valve activates. This ensures the valve shuts down the engine at the correct overspeed threshold.
Steps for calibration include:
- Gradually increase engine speed to note the shutdown point.
- Adjust the valve’s settings by turning the adjuster clockwise to increase the overspeed shutdown point.
- Test the engine again to ensure the desired setting is achieved.
- Lock the settings in place using a thread lock adhesive to prevent accidental changes.
