Application Fields: Gas Engineering, Urban Gas, Industrial Gas, Boiler Rooms, Catering Gas, Commercial Gas Safety Systems
I. Product Overview
DN15 Gas Emergency Shut-off Valve is an automatic shut-off device for gas pipeline safety control developed and manufactured by Zhejiang WEAJA Electronic Technology Co., Ltd. It is mainly used to quickly and urgently shut off the gas pipeline in emergency situations such as gas leakage, over-limit alarm, or system abnormality to prevent the expansion of gas accidents and ensure the safety of the gas environment.
The product can be used in conjunction with gas alarms, gas detectors, and gas safety control systems. When gas leakage is detected or the set alarm threshold is reached, the shut-off valve can automatically close the gas source within 1 second. It also supports manual closing and manual reset opening. The structure is reliable and suitable for various gas engineering projects such as residential gas, commercial kitchens, industrial gas equipment, etc.
II. Product Core Advantages
Suitable for common gas media such as natural gas and liquefied petroleum gas
DC pulse drive, no power consumption when power is off, safe and reliable
Valve closing time < 1 second, quickly cuts off the gas source
Supports linkage with gas alarms and gas detectors
Supports manual valve closing + manual reset opening for convenient emergency handling
Aluminum alloy valve body, lightweight structure and corrosion resistant
Explosion-proof certification Ex mb IIC T4 Gb, suitable for explosion-proof places
Complies with national explosion-proof implementation standard GB3836.9-2014
III. Typical Application Scenarios
Emergency Shut-off at the Household End of Urban Gas Pipeline Networks
Commercial Kitchens and Catering Gas Safety Systems
Supporting Industrial Boiler Rooms and Gas Heating Equipment
Gas Pipeline Safety Control in Chemical Plants and Gas Stations
Forms a gas safety system in conjunction with gas alarms and gas detectors
IV. System Linkage Instructions
The DN15 Gas Emergency Shut-off Valve can be used with combustible gas detectors and gas alarm controllers. When gas leakage exceeds the limit, the control system outputs a pulse signal to drive the shut-off valve to quickly close the gas channel, realizing the linkage closed-loop control of "detection—alarm—shut-off" and improving the overall safety level of the gas system.
V. Installation and Usage Points
Before installation, please confirm that the pipe diameter specification matches the threaded connection method
The shut-off valve should be installed before the gas meter or at key positions of the main gas pipeline
After closing, manual reset is required to reopen the gas supply
It is recommended to use in conjunction with a gas detection and alarm system to form a complete safety protection system
