Flame arrestor valve plus needle valve

The Flame Failure Protection Valve with Needle Valve is an integrated safety and control component designed for gas appliances, merging automatic leak prevention with precise gas flow adjustment to enhance safety and performance in residential and light commercial settings.

It combines dual safety and regulation functions in one compact unit: a flame failure shutoff (to stop gas flow if flames extinguish) and a needle valve (for fine-tuning pilot or burner gas supply). The solid brass construction provides exceptional corrosion resistance against gaseous fuels, extending service life while maintaining airtight reliability. Its intuitive textured adjustment knob enables easy, precise flow calibration, and the multi-port design supports seamless integration with standard gas lines—making it a practical choice for appliances requiring both safety and customizable gas delivery.

Structurally, this component integrates a brass core body, a flame-sensing safety mechanism, a precision needle valve, and multi-threaded ports (shown in the image). The brass body (machined to strict tolerances) ensures compatibility with natural gas and propane, resisting degradation from long-term gas exposure. The flame failure mechanism triggers automatic shutoff if appliance flames are lost (e.g., from drafts or spills), mitigating leak risks. The textured needle valve knob allows micro-adjustments to gas flow (critical for pilot light stability or burner intensity), while clearly marked ports (inlet, outlet, pilot) simplify correct installation. Threaded connections ensure leak-tight fits with standard appliance gas lines.

It is ideal for gas-powered appliances including stoves, ovens, countertop grills, and space heaters—used in homes, apartments, cafes, and small food service settings. It excels at protecting appliances and spaces from gas leaks while enabling precise gas flow control: for example, calibrating pilot light size on a stove or adjusting burner intensity on a grill. Whether installed in new appliances or as a safety/performance upgrade for existing systems, this Flame Failure Protection Valve with Needle Valve delivers dependable, versatile performance. It enhances appliance safety compliance, reduces gas waste through precise regulation, and supports intuitive operation, meeting the needs of manufacturers, installers, and users seeking integrated gas safety and control solutions.
