Description
The XF3 Series Industrial Gas Solenoid Valve (Normally Open) is a high-reliability safety device tailored for industrial natural gas systems. It maintains a normally open state during regular operation to guarantee smooth gas delivery, and activates rapid shut-off instantly when emergencies like gas leakage or pressure anomalies occur.
Its aluminum alloy valve body delivers excellent corrosion resistance and pressure endurance, making it well-suited for harsh industrial environments such as dusty workshops and outdoor gas terminals. NBR and FKM rubber options for sealing materials ensure optimal adaptability to diverse gas media and working conditions.
With an operating temperature range of -20°C ~ +60°C, it fits seamlessly into most industrial gas application scenarios. Combining manual opening and dual closing modes, it balances daily usability and emergency safety, shutting off in ≤ 1s to quickly cut off gas supply and avoid hazard escalation.
It supports thread and flange (PN16) connection interfaces for easy installation and integration with existing industrial gas pipelines. The stainless steel actuator boosts durability, enabling a 10-year service life. With IP66 protection, Ex mb IIC T6 Gb explosion-proof rating and GB 44016-2024 compliance, it is an essential reliable emergency safeguard for industrial gas systems.

Frequently Asked Questions (FAQ)
What is the default operation state of the XF3 Series Industrial Gas Solenoid Valve?
The XF3 Series is a "Normally Open" type valve. It remains open during daily normal operations to ensure continuous gas supply and only shuts down rapidly in the event of an emergency.
How fast does the valve shut off during an emergency?
The valve features an ultra-fast response safety mechanism, executing a complete shut-off within 1 second (≤ 1s) to immediately stop gas flow and prevent further hazards.
What pipeline connection standards are compatible with this valve?
It supports both thread connection (such as 1"FPT) and flange connection (PN16 interface, e.g., 4-Φ14, D85 spacing) configurations to adapt to standard industrial pipeline systems.
What materials are used for construction to resist corrosion?
The valve body is made of premium aluminum alloy for robust structure and corrosion resistance. The actuator is crafted from durable stainless steel, and options like NBR or FKM rubber are available for sealing to match various chemical environments.
Does this valve meet safety compliance for hazardous environments?
Yes, the valve features an IP66 ingress protection rating, is Ex mb IIC T6 Gb explosion-proof certified (encapsulated type), and fully complies with the GB 44016-2024 national safety standard.
