2025-12-02

Yanmar gas valves are key control components in Yanmar diesel engines or compressors, primarily used to cut off or regulate gas flow to ensure safe equipment operation. Here is the core information:

Structure and Function: Yanmar gas valves typically consist of a valve seat, valve plate, spring, and lift limiter. They automatically open and close based on gas pressure difference or spring force, requiring no external drive. Their core functions include:

Intake/Exhaust Control: Cutting off the supply of combustion air or gas in diesel engines; regulating gas intake and exhaust in compressors.
* Safety Isolation: Isolating the burner from the gas system, such as during hot air furnace operation.
