MQ-1/2-15-B Pneumatic Solenoid Valve 1/2 Inch Port Size 15mm Orifice Size Brass Body Material

Product Description:

The MQ Series is a two-way normally open solenoid valve designed for emergency automatic shut-off, specifically tailored to gas safety applications. It serves as a gas pipe breaker intended for urgent situations, providing a reliable solution to control gas flow when necessary.

This valve can be integrated with various detection and alarm systems, such as gas leakage sensors, fire alarm circuits, or other intelligent sensor modules. This integration enables either manual or automatic shutdown of the gas supply, either on-site or remotely, thereby enhancing safety in gas usage environments.

A notable feature of the MQ Series valve is its automatic closure mechanism triggered by strong vibrations. Once the valve closes in response to such disturbances, manual intervention is required to reopen it. This safety measure complies with regulations by preventing unintended gas flow after an incident.

Constructed from robust materials including brass, stainless steel, or aluminum alloy, and equipped with NBR seals, the valve ensures dependable, leak-tight performance. It is available in port sizes of 1/2", 3/4", and 1", with orifice sizes reaching up to 25mm, offering versatile flow capacity options.

Manufactured in Ningbo, China, and CE certified, the MQ Series solenoid valve is recognized for its quality and reliability, making it a trusted choice in gas safety systems worldwide.

Features:

The valve is designed to remain open in its normal, de-energized state, allowing continuous gas flow during standard operation. This normally open function ensures that the system operates smoothly without interruption under regular conditions.

In emergency situations, the valve is equipped with an automatic shut-off feature. It will immediately close if intense vibrations are detected or if it receives an emergency signal from gas detectors or fire alarm systems. This rapid response helps to prevent potential hazards.

Once the valve has automatically closed due to an emergency, it cannot be reopened without manual intervention. This manual reset operation guarantees that the system is safely restarted only after proper checks, enhancing overall safety after an incident.

The valve incorporates a self-locking mechanism that significantly boosts safety by preventing unintended reopening. This accident self-locking capability ensures that once triggered, the valve remains securely closed until manually reset.

Featuring a straightforward and efficient design, the valve boasts a quick response time of less than 0.5 seconds. Its simple structure contributes to reliable performance and fast actuation during critical moments.

With extremely low load loss, the valve minimizes pressure drops, promoting efficient operation of the entire gas system. This characteristic helps maintain optimal flow and reduces energy consumption.

To accommodate diverse applications, the valve is available in multiple body materials, including brass, stainless steel, and aluminum alloy. This variety allows selection based on specific environmental or mechanical requirements.

Offering flexibility in installation, the valve comes in a range of port sizes—1/2", 3/4", and 1"—with G and NPT thread options. This wide port size range supports integration into various piping systems with ease.

Power supply versatility is also ensured, with multiple voltage variants available. Choices include DC 12V and 24V, as well as AC options at 24V, 110V, and 220V operating at 50/60Hz frequencies, catering to a broad spectrum of control setups.

Certified with CE marking, the valve meets international safety and quality standards, offering confidence in compliance and performance for global applications.

Finally, the production capability is robust, with a capacity of 50,000 units per month and 10,000 units weekly. This high output ensures a dependable supply for large-scale orders and consistent availability for customers.

Technical Parameters:

Applications:

These systems are designed to detect gas leaks from sources such as town gas, natural gas, and LPG. When a leak is detected by the sensors, an emergency shut-off mechanism is activated to prevent any hazardous situations.

Fire alarm systems are integrated with gas shut-off circuits to automatically stop the supply of gas if a fire is detected. This integration enhances overall safety by minimizing the risk of gas-related fire incidents.

Safety shut-off devices are implemented in residential homes using natural gas and LPG installations. These mechanisms help protect households by quickly stopping gas flow in emergency situations.

In commercial settings such as restaurants, hotels, and other commercial kitchens, emergency gas isolation systems are used. These systems help manage gas supply safely and reduce the risk of accidents.

For industrial applications, safety isolation is provided on pipelines transporting natural gas and LPG. This is critical for controlling gas flow and ensuring safety throughout the distribution process.

Boiler safety systems include emergency gas shut-off features that activate during hazardous conditions, protecting boilers and preventing potential gas hazards.

Gas metering and regulation skids are equipped with safety isolation mechanisms. These ensure safe operation by isolating gas flow when issues are detected during metering or regulation.

Industrial burners and heating equipment that use gas are safeguarded by safety shut-off systems. These systems quickly stop gas supply to prevent accidents and ensure safe operation.
