Product Description

Description

The XF3III Series Industrial Gas Emergency Shut-off Solenoid Valve (Keep Normally Open) is specialized for small-to-medium industrial natural gas pipelines (DN15–DN25), providing reliable emergency shut-off. Tailored for natural gas, its aluminum alloy body is lightweight yet durable, with excellent pressure and corrosion resistance. Sealing material offers NBR/FKM rubber options for superior airtightness. Operating at -20°C ~ +60°C, it suits workshops and gas distribution stations. With manual opening and dual closing methods, it closes in ≤1s to stop gas leakage instantly. Its stainless steel actuator, IP66 protection and 10-year service life ensure long-term stability. Equipped with Ex mb IIC T6 Gb explosion-proof grade and compliant with GB 44016-2024, it meets strict industrial safety standards, ideal for small-to-medium industrial gas pipeline protection.

Frequently Asked Questions

What pipeline sizes is the XF3III Series compatible with?

The XF3III Series is designed for small-to-medium industrial natural gas pipelines ranging from DN15 to DN25, making it ideal for workshops, factories, and gas distribution stations.

What sealing material options are available, and how do they differ?

The valve offers both NBR (Nitrile Butadiene Rubber) and FKM (Fluoroelastomer) sealing options. NBR is suitable for standard operating conditions, while FKM provides enhanced chemical resistance and is better suited for more demanding environments with higher temperature ranges.

How quickly does the valve close in an emergency situation?

The XF3III valve closes in ≤1 second upon receiving an emergency signal, effectively stopping gas leakage almost instantly. It supports dual closing methods for added reliability, along with a manual opening mechanism for maintenance and reset operations.

Is the XF3III Series suitable for use in hazardous or explosive environments?

Yes. The valve is certified with an Ex mb IIC T6 Gb explosion-proof grade, meaning it is specifically tested and approved for use in environments where flammable gases, including natural gas, may be present. It fully complies with GB 44016-2024 industrial safety standards.

What is the expected service life and protection rating of this valve?

The XF3III Series is engineered for a 10-year service life under normal operating conditions. Its stainless steel actuator and IP66 protection rating ensure resistance against dust ingress and powerful water jets, supporting long-term reliability in industrial settings.

What temperature range can the XF3III Series operate in?

The valve operates reliably within a temperature range of -20°C to +60°C, making it suitable for a wide variety of industrial environments, including cold storage facilities, outdoor gas distribution stations, and indoor workshops with temperature fluctuations.
