High flow flame arrestor check valve for OXYGENE, entry 20x150 right female.

High flow flame arrestor check valve for OXYGENE, entry 20x150 right female.

The LE LORRAIN high-flow oxygen non-return valve and flashback arrestor is designed to protect oxygen installations against reverse gas flow and flame flashback. It is suited to welding workshops, oxy-fuel cutting stations, maintenance departments and industrial environments requiring high gas flow rates.

Its 20x150 right-hand female inlet allows installation on compatible equipment. The oxygen-specific configuration supports clear gas identification and helps professionals build a consistent gas distribution system.

When installed on a suitable supply line, the device helps protect upstream equipment. It limits the risk of an incident travelling back towards the regulator or gas distribution network while maintaining the gas circulation required for high-flow applications.

LE LORRAIN manufacturing is aimed at professionals seeking robust, clearly identified equipment developed for industrial use. This valve is suitable for installations where stable gas flow, controlled operation and operator protection are daily priorities.
