What is the second gas valve section referred to on a dual gas valve?

The second gas valve section in a dual gas valve setup is indeed referred to as a diaphragm and working gas system. This section plays a crucial role in the regulation and control of gas flow in appliances that utilize dual gas supplies.

In this system, the diaphragm responds to pressure changes, helping to maintain the proper gas flow and preventing any leaks or unsafe conditions. The working gas section ensures that gas is delivered at the appropriate pressure to the burner system, facilitating proper combustion. This configuration allows for more precise control over the fuel being supplied, enhancing safety and efficiency in commercial food equipment applications.

Other terms in the options refer to different components or functionalities within gas safety and control systems. For example, a safety valve is designed to automatically shut off gas flow in the case of overpressure or a fault condition, while a flow control section is typically responsible for adjusting and managing gas flow rates. A bypass line, on the other hand, usually allows gas to flow around a component when it is closed off, but does not directly relate to the functioning of the dual gas valve's diaphragm system. Understanding these distinctions is key to comprehending how gas systems operate in a commercial setting.
