Product Description:
The MQ Series is a two-way, normally open emergency automatic shut-off solenoid valve, specially designed for gas safety applications. It serves as a gas pipe breaker intended for emergency situations, allowing for quick and reliable interruption of gas flow when necessary.
This valve can be integrated with gas leakage detection sensors, fire alarm systems, or other intelligent sensor modules. It enables both on-site and remote shutdown of gas supply, 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. After the valve closes automatically, it requires manual operation to reopen, ensuring compliance with safety regulations in case of an accident.
Constructed from durable materials such as brass, stainless steel, or aluminum alloy and equipped with NBR seals, the valve guarantees a reliable, leak-tight performance. It is available in port sizes of 1/2", 3/4", and 1", offering various flow capacities with orifice sizes up to 25mm.
Manufactured in Ningbo, China, and CE certified, the MQ Series valve is recognized for its high quality and dependable performance in gas safety systems worldwide.
Features:
The valve is designed with a normally open function, meaning it stays open when there is no electrical power, allowing gas to flow uninterrupted during regular operation.
In cases of emergency, the valve automatically shuts off. It closes instantly if it detects strong vibrations or receives emergency signals from connected gas detectors or fire alarm systems.
Once the valve has closed automatically, it cannot be reopened without manual intervention. This manual reset feature ensures that the system restart is performed safely after any trip event.
Equipped with a self-locking mechanism, the valve provides exceptionally high safety by preventing accidental or unintended reopening, thereby enhancing operational security.
The valve’s simple design promotes a rapid response time of less than 0.5 seconds, ensuring quick action when needed.
With extremely low load loss, the valve causes minimal pressure drop, which contributes to the efficient operation of the overall system.
To accommodate various application needs, the valve is available in multiple body materials, including brass, stainless steel, and aluminum alloy.
The product offers flexible integration options by providing a wide range of port sizes, such as 1/2", 3/4", and 1" with G or NPT connections.
It supports a variety of voltage options, including DC 12V and 24V, as well as AC 24V, 110V, and 220V (50/60Hz), making it compatible with diverse control systems.
Certified by CE, the valve meets international safety and quality standards, ensuring reliable and safe operation.
Backed by a high production capacity of 50,000 units per month and 10,000 units per week, the manufacturer can reliably supply the valve in large quantities to meet bulk order demands.

Applications:
Gas Leak Detection Systems
These systems are designed to detect gas leaks using specialized sensors that monitor town gas, natural gas, and LPG. When a leak is detected, the system triggers an emergency shut-off to prevent hazardous situations.
Fire Alarm Systems
Fire alarm systems can be integrated with gas shut-off circuits to automatically stop the gas supply in the event of a fire. This integration enhances safety by reducing the risk of gas-related accidents during fire emergencies.
Residential Gas Systems
Safety shut-off mechanisms are implemented in home natural gas and LPG installations to protect residents from potential gas leaks or malfunctions, ensuring a secure living environment.
Commercial Gas Systems
In commercial settings such as restaurants, hotels, and commercial kitchens, emergency gas isolation systems are crucial. These systems quickly cut off the gas supply to prevent accidents and ensure safety during emergencies.
Industrial Gas Pipelines
Safety isolation is a key feature in the management of natural gas and LPG distribution lines in industrial environments. This helps to control and contain any leaks or issues within the pipeline infrastructure.
Boiler Systems
Boiler safety systems incorporate emergency gas shut-off capabilities to protect equipment and personnel by stopping the gas flow during unsafe conditions.
Gas Metering Stations
Gas metering and regulation stations use safety isolation mechanisms within their skids to ensure safe handling and control of gas during measurement and distribution processes.
Industrial Burners
Industrial burners and heating equipment are equipped with safety shut-off systems to immediately stop the gas supply in case of any operational faults or emergencies.
