3/4'' Port Size 20mm Orifice Size MQ-3/4-20 Pneumatic Solenoid Valve Featuring

Product Description:

The MQ Series is a two-way normally open emergency automatic shut-off solenoid valve, specifically designed for gas safety applications. It functions as a gas pipe breaker intended for emergency situations, providing a critical safety mechanism in gas supply systems.

This valve can be integrated with gas leakage detection sensors, fire alarm circuits, or various intelligent sensor modules. Such connections enable both on-site and remote shutdown of the gas supply, either manually or automatically, thereby enhancing safety during gas usage.

Equipped with an automatic closing feature, the valve activates upon detecting strong vibrations. Once it closes in response to such events, manual intervention is required to reopen it. This design complies with safety regulations and helps prevent accidents by ensuring the valve remains closed until inspected.

Built from robust materials such as brass, stainless steel, or aluminum alloy, and sealed with NBR components, the MQ Series valve guarantees reliable, leak-tight performance. It is available in port sizes of 1/2", 3/4", and 1", with orifice sizes up to 25mm, offering versatile flow capacities to suit different applications.

Manufactured in Ningbo, China, and holding CE certification, this valve is recognized for its quality and dependability in gas safety systems worldwide.

Features:

The valve features a Normally Open function, which means it stays open when not energized, allowing uninterrupted gas flow during regular operations.

In case of emergencies, the valve is equipped with an Automatic Shut Off system that activates upon detecting strong vibrations or receiving emergency signals from gas detectors or fire alarm systems, effectively closing the valve to prevent hazards.

After an automatic shutdown, reopening the valve requires manual intervention. This manual reset operation ensures that the system restarts safely following any trip event.

Safety is further enhanced by an accident self-locking mechanism, which guarantees exceptionally high security by preventing unintended valve opening.

Designed with simplicity in mind, the valve offers a quick response time of less than 0.5 seconds, enabling rapid reaction to control signals or emergency conditions.

Efficiency is maintained through extremely low load loss, resulting in minimal pressure drop and optimized system performance.

To accommodate various applications, the valve body is available in multiple material options, including brass, stainless steel, and aluminum alloy.

Installation flexibility is provided by a wide range of port sizes, available in 1/2", 3/4", and 1" with G or NPT connection standards.

The valve supports multiple voltage configurations such as DC 12V, 24V and AC 24V, 110V, 220V at 50/60Hz, ensuring compatibility with diverse control systems.

Certified with the CE mark, the valve meets international quality and safety standards, offering reliable performance.

With a robust manufacturing capacity of 50,000 units per month and 10,000 units per week, the production is well-equipped to meet large order demands reliably.

Technical Parameters:

Applications:

These systems are equipped with sensors that detect gas leaks from various sources such as town gas, natural gas, and LPG. When a leak is identified, an emergency shut-off mechanism is activated immediately to prevent potential hazards.

Fire alarm systems can be integrated with gas shut-off circuits to enhance safety measures. In the event of a fire, the system automatically triggers the closure of gas supply lines to reduce the risk of explosions or further damage.

For homes using natural gas or LPG, safety shut-off units are installed to provide immediate gas isolation in case of emergencies. These devices help protect households from gas leaks and related dangers.

Restaurants, hotels, and other commercial kitchens utilize emergency gas isolation systems to ensure safety during unexpected gas leaks or malfunctions. These systems play a critical role in preventing accidents in busy commercial environments.

In industrial settings, natural gas and LPG distribution lines are equipped with safety isolation mechanisms. These systems help to quickly shut off gas flow during emergencies, safeguarding both infrastructure and personnel.

Boilers rely on emergency gas shut-off systems to maintain safe operation. In the event of abnormal conditions or failures, the gas supply is cut off to prevent hazards associated with boiler malfunction.

Gas metering and regulation skids are fitted with safety isolation devices to manage and control gas flow securely. This ensures that any irregularities in gas supply can be swiftly addressed by isolating the affected sections.

Gas-fired burners and heating equipment in industrial applications are equipped with safety shut-off systems. These devices help prevent accidents by immediately stopping gas flow in dangerous situations.
