Chenan Gas Appliance Co., Ltd was founded in 2014.In response to gas disasters caused by earthquakes that may result in devastating harm to people’s lives and properties, the company started to develop the “Earthquake Gas Line Breaker” in 2010 and applied for a patent in four countries of Taiwan, USA, Japan and China. Currently, the patent has first been approved by Japan. After three years of R&D, the company has succeeded in introducing a device with simple mechanical structure and yet able to achieve the safest gas breaking effect (activated at magnitude 5 earthquake). Released in 2014, it was awarded with a Gold Medal at “2014 Taipei Int’l Invention Show & Technomart.”

The “Electronic Gas Shutoff Valve” is patent pending in Taiwan, Germany, France, Italy, Spain, Canada, Australia, South Korea and other countries. The “Earthquake Gas Line Breaker” unit itself features double actions capable of achieving “earthquake shutoff” and “electronic monitoring shutoff,” and has the merits of stable quality and low price.

Chenan Gas Appliance Co., Ltd is dedicated to developing gas safety products, in particularly in gas safety during the event of earthquake. The “Earthquake Gas Line Breaker” had been tested on a shake table at the Disaster Prevention Laboratory of National Kaohsiung First University of Science. When the device was tested with a simulated earthquake of magnitude 5 on the Richter scale (200gal) on three angles of 0 º, 45 º and 90 º), it was able to instantly shutoff gas supply mechanically without power assistance.
