High-Flow Butane Refill Valve for Industrial Heaters with Anti-Backflow Protection

The High-Flow Butane Refill Valve is engineered for industrial applications, delivering rapid refills to heaters, soldering irons, and construction torches without compromising safety. Its stainless steel body and Viton® O-rings resist corrosion from butane’s additives, ensuring longevity in harsh environments. The valve’s anti-backflow system prevents gas from re-entering the canister during disconnection, reducing waste and fire hazards. A quick-release lever allows for one-handed operation, while the transparent flow indicator shows real-time refill progress, preventing overpressure. Tested to withstand -20°C to 60°C temperatures, this valve is trusted by contractors and workshop managers for its reliability under extreme conditions.

Bullet Points:

• Anti-Backflow Protection: Stops gas from flowing backward into the canister.
• Quick-Release Lever: Enables single-handed attachment/detachment.
• Transparent Flow Indicator: Visual confirmation of refill completion.
• Viton® Corrosion Resistance: Withstands butane’s chemical additives.
• High-Flow Orifice: Fills 500ml tanks in under 20 seconds.

Specific Application Scenario:
Construction crews use this valve to refill roofing torches on-site, ensuring uninterrupted workflow during cold weather without risking frozen components.
