Flame Arrestor with NRV 3/8″

Flame arrestors are designed to prevent the propagation of flames and sparks from entering or escaping a pipeline or vessel. In gas systems, they are particularly essential to arrest flames that could reach areas with high gas concentrations.
> Backfire Prevention: In gas pressure reducing systems, backfires can occur due to various factors, such as sudden pressure changes, ignition sources, or equipment failures. A backfire is a dangerous event where a flame travels back into the pipeline or equipment. The flame arrestor is positioned in the gas line to halt the progress of any backfire and prevent it from reaching areas where there is a dense concentration of fuel, thereby averting accidents and explosions.
> Non-Return Valve Function: The built-in non-return valve (also known as a check valve) ensures that gas flows in one direction only. It prevents reverse flow, which can be caused by pressure differentials or system fluctuations. This is crucial to maintain the integrity and safety of the gas distribution system.
> Prevents Gas Leakage: The non-return valve within the flame arrestor ensures that gas flows in the intended direction, preventing any unintended leakage or reverse flow of gas, which can be critical in maintaining system integrity and safety.
