Product Description:
The MQ Series is a two-way, normally open solenoid valve designed for emergency automatic shut-off in gas safety applications. It is specifically engineered to function as a gas pipe breaker during emergencies, ensuring rapid response when gas safety is compromised.
This valve can be integrated with various detection systems such as gas leakage sensors, fire alarm circuits, or intelligent sensor modules. This allows for both on-site and remote gas supply shutdowns, either manually or automatically, providing an essential layer of safety in gas usage environments.
One notable feature of the MQ Series is its auto-close mechanism. When strong vibrations are detected, the valve automatically shuts off the gas supply. After this automatic closure, manual intervention is required to reopen the valve, thereby complying with safety regulations and preventing accidental gas flow after an incident.
The valve is constructed from high-quality materials, including durable brass, stainless steel, or aluminum alloy bodies combined with NBR seals to ensure leak-tight and reliable performance. It is available in port sizes of 1/2", 3/4", and 1", accommodating orifice sizes up to 25mm for various flow capacities.
Manufactured in Ningbo, China, and CE certified, the MQ Series solenoid valve is widely trusted for its durability, quality, and reliability in the field of gas safety systems.
Features:
The valve operates normally in an open position when it is de-energized, allowing gas to flow freely during regular operation. This feature ensures continuous and uninterrupted gas supply under standard conditions.
In case of emergencies, the valve is designed to automatically shut off. It will close instantly upon detecting strong vibrations or upon receiving emergency signals from gas detectors or fire alarm systems. This automatic response enhances safety by preventing potential hazards.
Once the valve has closed automatically, it requires a manual reset to reopen. This manual intervention guarantees a safe and controlled restart after any trip event, preventing accidental or premature valve activation.
The valve includes a self-locking mechanism that significantly enhances safety by ensuring it remains securely closed during accident conditions. This feature adds an extra layer of protection against unintended gas flow.
Featuring a simple structural design, the valve delivers a rapid response time of less than 0.5 seconds. This quick reaction capability is critical for efficient and effective control within gas systems.
Thanks to its design, the valve exhibits extremely low load loss, minimizing pressure drop and promoting efficient operation throughout the system. This efficiency supports better performance and energy savings.
Diverse material options are available for the valve body, including brass, stainless steel, and aluminum alloy. This variety allows customization to meet different application needs and environmental conditions.
The valve comes in multiple port sizes such as 1/2", 3/4", and 1" with G or NPT connection types, enabling flexible integration into various piping systems.
To accommodate different control system requirements, the valve supports multiple voltage options, including DC 12V, 24V, and AC 24V, 110V, and 220V at 50 or 60 Hz frequencies.
Certified with the CE mark, the valve meets international safety and quality standards, providing users with assurance of product reliability and compliance.
Supported by a robust production capacity of 50,000 units per month and 10,000 units per week, the manufacturer ensures a steady and reliable supply, making it well-suited for large-scale orders.

Applications:
Gas Leak Detection Systems
These systems are equipped with sensors that detect gas leaks involving town gas, natural gas, and LPG. Upon detection, they trigger an emergency shut-off mechanism to prevent accidents and ensure safety.
Fire Alarm Systems
Fire alarm circuits can be integrated with gas safety systems to automatically cut off the gas supply in the event of a fire. This integration enhances overall safety by preventing the risk of gas-related explosions during fire emergencies.
Residential Gas Systems
Safety shut-off devices are installed in home natural gas and LPG systems to provide reliable protection for residents. These devices act swiftly to stop the flow of gas in any hazardous situation, reducing potential risks.
Commercial Gas Systems
In commercial settings such as restaurants, hotels, and professional kitchens, emergency gas isolation systems are employed. These systems ensure rapid shut-off of gas supply to safeguard people and property during emergencies.
Industrial Gas Pipelines
Safety isolation mechanisms are critical in natural gas and LPG distribution networks within industrial environments. These features help to maintain controlled gas flow and isolate segments when necessary to avoid accidents.
Boiler Systems
Boilers are equipped with emergency gas shut-off systems designed to protect both equipment and personnel. These safety measures instantly halt gas supply to the boiler during abnormal conditions.
Gas Metering Stations
Safety isolation is also essential at gas metering and regulation stations. These isolation systems ensure secure handling and control of gas flow through measurement and regulation equipment.
Industrial Burners
Gas-fired burners and industrial heating equipment incorporate safety shut-off features to prevent hazardous situations. These systems act decisively to stop gas supply, thereby enhancing operational safety.
