Product Description
DRQF series emergency shut-off valve：
DRQF series electromagnetic gas emergency shut-off valve is a kind of supporting safety device that is widely used for urban residents, commercial and industrial gas supply network. It can be used as a set with combustible gas alarm or alarm apparatus. This product is a new product with the invention patent owned by company. It adopts unique mechanical self-locking mechanism. It has stable and reliable performance and is controlled by multiple shutoff valves control method: power-on shutoff valve, power-off shutoff valve, signal shutoff valve, manual shutoff valve. The advanced pilot- operated structure can ensure valve open with pressure smoothly.
Range of application：
1, It can connect with combustible gas monitoring system. When gas leakage reaches predetermined concentration, the main gas supply valve will be closed automatically to cut off gas supply and prevent malignant accident.
2, Connect with safety controller of thermal equipment. When exceeding the set limit, close gas supply valve automatically to stop gas supply.
3, It can connect with central firefighting alarm system of a high-rise building. When ther is a fire, gas supply will be cut off automatically to prevent accidents.
4, It can be used in gas supply network of cities and plants. It can cut off gas supply at the accident site by remote control.
