What is the function of a vent limiting orifice in a redundant gas valve?

The function of a vent limiting orifice in a redundant gas valve is to ensure regulation and proper safe operation of the gas system. This component plays a crucial role in maintaining consistent pressure within the system, which is essential for optimal performance and safety. By regulating the airflow and gas pressure through the valve, the vent limiting orifice helps to prevent issues such as overpressure, which can lead to dangerous conditions or equipment failure. Its design allows for controlled venting, enhancing the reliability of the gas valve's performance in a redundant system where safety is paramount. This is vital in ensuring that even if one component fails, the system can still operate effectively and safely, minimizing the risk of gas leaks or other hazards.
