Product Description:
The MQ Series is a two-way normally open solenoid valve designed specifically for emergency automatic shut-off in gas safety applications. Engineered to act as a gas pipe breaker during emergencies, it plays a crucial role in ensuring the secure use of gas.
This valve can be integrated with gas leakage detection sensors, fire alarm systems, or other intelligent sensor modules. Such connectivity allows for on-site or remote gas supply shutdown, either manually or automatically, enhancing overall safety measures in gas usage environments.
One of the key features of the MQ Series valve is its automatic closure mechanism triggered by strong vibrations. Once the valve closes due to detected vibrations, it requires manual intervention to reopen, aligning with safety regulations aimed at preventing accidents.
Constructed from robust materials such as brass, stainless steel, or aluminum alloy and equipped with NBR seals, the valve ensures a reliable and leak-tight performance. It is available in various port sizes including 1/2", 3/4", and 1", with orifice diameters reaching up to 25mm to accommodate different flow capacities.
Manufactured in Ningbo, China, and certified by CE standards, the MQ Series solenoid valve is recognized for its high quality and dependable performance within gas safety systems worldwide.
Features:
Normally Open Function
The valve remains open when it is not energized, allowing gas to flow freely during normal operation. This ensures continuous and stable supply under standard conditions.
Emergency Automatic Shut Off
In the event of strong vibrations or upon receiving emergency signals from gas detectors or fire alarms, the valve automatically closes to prevent potential hazards. This feature provides critical safety intervention.
Manual Reset Operation
After the valve has closed automatically due to an emergency, it can only be reopened through manual reset. This ensures that the system is safely inspected and restarted after any trip event.
Accident Self-Locking
The valve is equipped with a self-locking mechanism that delivers exceptionally high safety performance. This feature helps to securely lock the valve position during incidents.
Simple Structure & Quick Response
Featuring a straightforward design, the valve achieves a fast response time of less than 0.5 seconds, allowing for quick action when needed.
Extremely Low Load Loss
The valve design minimizes pressure drop across the system, leading to efficient and smooth operation with minimal energy loss.
Multiple Body Material Options
To accommodate different applications, the valve is available in brass, stainless steel, or aluminum alloy materials, providing flexibility depending on environmental and operational requirements.
Wide Port Size Range
This valve offers port sizes in 1/2", 3/4", and 1" with G and NPT connection types, making it adaptable for a variety of system configurations.

Applications:
Gas Leak Detection Systems
These systems are designed to promptly detect any leakage of gases such as town gas, natural gas, and LPG. Upon detection, the emergency shut-off mechanism is activated to prevent potential hazards and ensure safety.
Fire Alarm Systems Integration
Gas shut-off systems can be integrated with fire alarm circuits, enabling automatic gas valve closure in the event of a fire. This integration helps to minimize the risk of further damage caused by leaking gas during fire incidents.
Residential Gas Systems
Safety shut-off solutions are implemented in homes utilizing natural gas and LPG. These mechanisms provide homeowners with added security by automatically stopping the gas supply if an unsafe condition is detected.
Commercial Gas Systems
In commercial environments such as restaurants, hotels, and kitchens, emergency gas isolation systems are critical. They ensure rapid response to gas leaks, protecting people and property in these high-risk areas.
Industrial Gas Pipelines
Safety isolation plays a vital role in industrial natural gas and LPG distribution lines. These systems help maintain operational safety by isolating sections of the pipeline when abnormal gas flow or leakage is detected.
Boiler Systems
Emergency gas shut-off mechanisms are integrated within boiler safety systems to prevent accidents. By automatically cutting off the gas supply under hazardous conditions, these systems protect both equipment and personnel.
Gas Metering Stations
At gas metering and regulation skids, safety isolation systems ensure secure handling of gas flow. These mechanisms enable controlled shut-off in case of leaks or abnormalities, maintaining system integrity.
Industrial Burners
Gas-fired burners and heating equipment are equipped with safety shut-off devices. These ensure that the gas supply is immediately interrupted if any unsafe operation is detected, enhancing operational safety.
