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.

Under regular working conditions, the valve stays open to allow unimpeded natural gas flow. In the event of a gas leak or pressure anomaly, it receives an electrical signal or manual command to trigger a rapid shut-off in 1 second or less (≤1s), immediately cutting off the gas supply.
The XF3 Series supports both threaded (such as 1" FPT) and flanged (such as PN16, 4⌀14, D85) connection interfaces, making it highly versatile for integration into different configurations of existing industrial natural gas pipelines.
Yes, it is designed with an IP66 protection rating and an Ex mb IIC T6 Gb encapsulated explosion-proof classification. Constructed with a highly durable aluminum alloy valve body and a stainless steel actuator, it is well-suited for dusty workshops and outdoor gas terminals.
The valve features dual closing modes: it can be closed via a DC pulse energized signal (such as Active Pulse AC220V) or closed manually. Re-opening the valve after a safety shut-off must be performed manually to ensure safe system restoration.
The operating temperature range is -20°C to +60°C. For sealing compatibility with diverse gas media and custom working conditions, both NBR and FKM rubber sealing materials are available.
The XF3 series conforms to the GB 44016-2024 execution standard. Built with high-grade stainless steel and aluminum materials, it boasts a typical service life of 10 years.
