Product Description:
The MQ Series is a two-way, normally open emergency automatic shut-off solenoid valve, specifically designed for gas safety applications. It serves as a gas pipe breaker intended for emergency situations, allowing for rapid response to potential hazards.
This valve can be integrated with gas leakage detection sensors, fire alarm circuits, or other intelligent sensor modules. Such connectivity enables both on-site and remote gas supply shutdowns, either manually or automatically, thereby enhancing safety during gas usage.
One of the key features of the MQ Series valve is its automatic closing mechanism, which activates upon detecting strong vibrations. Once the valve has closed, manual operation is necessary to reopen it, ensuring compliance with safety regulations in case of an accident.
Constructed from robust materials including brass, stainless steel, or aluminum alloy, and equipped with NBR seals, this valve guarantees reliable, leak-tight performance. It is available with port sizes of 1/2", 3/4", and 1", offering flow capacity with orifice sizes up to 25mm.
Manufactured in Ningbo, China, and CE certified, the MQ Series valve is recognized for its quality and dependability in gas safety systems worldwide.
Features:
The valve features a Normally Open function, which means it remains open when not energized, allowing gas to flow freely during standard operation.
In case of emergencies, the valve is equipped with an automatic shut-off mechanism. It closes automatically upon detecting strong vibrations or receiving emergency signals from gas detectors or fire alarm systems.
Once the valve has closed automatically, it requires manual resetting to reopen. This manual reset operation ensures a safe and controlled restart following any trip event.
Safety is further enhanced by an accident self-locking feature, which provides a highly reliable locking mechanism to prevent unintended valve operation.
The valve's simple structure contributes to a rapid response time of less than 0.5 seconds, enabling swift reaction during critical situations.
Designed for efficiency, the valve causes extremely low load loss, resulting in minimal pressure drop and optimal system performance.
To accommodate various application needs, the valve body is available in multiple materials, including brass, stainless steel, and aluminum alloy.
It also comes in a diverse range of port sizes, such as 1/2", 3/4", and 1" with G or NPT thread options, providing flexibility for different system configurations.
The valve supports multiple voltage options, including DC 12V and 24V, as well as AC 24V, 110V, and 220V at 50/60Hz, ensuring compatibility with various control systems.
This product is CE certified, meeting international standards for safety and quality assurance.
With a robust production capacity of 50,000 units per month and 10,000 units per week, it guarantees a reliable supply for large-scale orders.

Applications:
Gas Leak Detection Systems
These systems are equipped with sensors specifically designed to detect gas leaks for various types of gases such as town gas, natural gas, and LPG. Upon detection of any leakage, the system promptly triggers an emergency shut-off to prevent any hazardous incidents.
Fire Alarm Systems
Fire alarm systems can be integrated seamlessly with gas shut-off mechanisms. In the event of a fire, these integrated circuits automatically activate the gas shut-off, ensuring additional safety by minimizing the risk of gas-related accidents.
Residential Gas Systems
For homes using natural gas or LPG, safety shut-off devices are installed as a critical precaution. These systems provide reliable protection by automatically cutting off the gas supply when unsafe conditions are detected.
Commercial Gas Systems
In commercial settings such as restaurants, hotels, and commercial kitchens, emergency gas isolation systems play an essential role. These systems are designed to quickly shut off gas supply during emergencies to protect people and property.
Industrial Gas Pipelines
Safety isolation mechanisms are implemented in large-scale natural gas and LPG distribution pipelines. These systems ensure that in case of any faults or leaks, the affected section can be isolated immediately to prevent escalation.
Boiler Systems
Boiler safety systems incorporate emergency gas shut-off solutions to safeguard the operation. If an abnormal condition is detected, these mechanisms activate to halt the gas supply and prevent potential hazards.
Gas Metering Stations
Gas metering and regulation stations utilize safety isolation features within their skids. This helps maintain safety by allowing quick isolation of gas flow when irregularities occur.
Industrial Burners
Industrial burners and heating devices that use gas rely on safety shut-off systems. These are crucial for ensuring safe operation by immediately stopping gas supply if unsafe conditions arise.
