CAATM JT-CA319 +DN15Smart Home Methane Gas Detector and Alarm System with 6-12V Solenoid Valve, Gas Leak Detector for House Security
The JT-CA319+DN15 Valve Home Combustible Gas Detector is a smart security product designed specifically for homes using piped natural gas (methane). It integrates four functions: detection, alarm, valve shut-off, and ventilation, providing proactive safety protection. When the detector detects that the methane concentration reaches the warning level (≥20% LEL), it will instantly emit a strong audible and visual alarm and simultaneously output two sets of key signals: a DC 12V pulse signal immediately shuts off the solenoid valve on the gas pipeline, cutting off the gas supply at its source; the other set of passive switching signals will activate the exhaust fan to forcefully expel the leaking gas. This systematic solution maximizes the prevention of fire and explosion accidents, ensuring the safety of you and your family's life and property around the clock.


【Dual Safety Linkage】 Upon detecting a methane (natural gas) leak, it not only issues an audible and visual alarm but also automatically activates a DN15 solenoid valve to cut off the gas supply and simultaneously activates an exhaust fan to accelerate diffusion, forming a dual safety barrier of "cut-off + elimination".
【Specialized Methane Detection】 Employs a semiconductor sensor specifically optimized for methane gas detection, exhibiting high sensitivity to natural gas leaks with a response time of less than 20 seconds, providing more timely protection.
【Stable and Durable, Strong Anti-interference】 Made of ABS material with anti-static, anti-oil fume, and anti-alcohol design, it can reliably withstand the complex environment of a kitchen, effectively preventing false alarms and missed alarms, ensuring reliable performance.
【Intelligent Design, Easy Installation】 Intelligent circuit design, simple operation, plug and play. Designed for home use, easy installation; users can enjoy professional-grade safety protection without complex settings.







We deeply understand the needs of home gas safety. The JT-CA319+DN15 Valve is not just a simple alarm, but a complete "detection-alarm-response" safety system. It overcomes the shortcomings of traditional products that "only alarm but do not act," proactively mitigating risks by automatically cutting off the gas supply and activating ventilation. Its specialized methane semiconductor sensor and strong anti-interference capabilities ensure the accuracy and reliability of the alarm, giving you peace of mind.
