Robust One Inch Lighter Gas Control Valve for Hazardous Industrial
Fuel Systems with Explosion-Proof Seals and Thermal Lock Technology
Product Description:
Engineered for extreme environments, this industrial-grade one-inch
lighter gas valve delivers unmatched safety in propane/butane fuel
management. Crafted from marine-grade brass with nickel-plated
components, it regulates high-pressure gas flow (up to 500 PSI) in
petrochemical plants, foundries, and mining operations. The
dual-action safety mechanism combines manual shutoff with automatic
thermal lockdown – when ambient temperatures exceed 150°C, the
fusible link triggers instant gas disconnection. Precision-machined
NPT threads ensure leak-proof pipeline integration, while
corrosion-resistant seals withstand chemical exposure and moisture.
This ATEX-certified gas cutoff device features flame-arresting mesh
to prevent flashback ignition and meets ISO 9001 safety standards.
The ergonomic red handwheel enables quick emergency response, and
its reinforced stem maintains sealing integrity after 10,000+
cycles. Ideal for furnace fuel lines, boiler systems, and mobile
equipment where reliability prevents catastrophic failures. All
valves undergo hydrostatic testing at 2x operating pressure and
helium leak detection before shipment.
Bullet Points
✅ High-torque brass core resists gas corrosion
✅ One-inch NPT threads for universal pipeline integration
✅ Certified for propane/butane fuel control systems
✅ Dual O-ring seals prevent hazardous leaks
✅ Manual override for emergency gas shutoff
Application Scenario
Installed in steel mill furnace gas lines to regulate propane flow
and prevent explosions during temperature spikes.

FAQ
Q: What pressure can this gas valve withstand?
A: Rated for 500 PSI continuous operation with 1500 PSI burst
pressure.
Q: Is the thermal lock mechanism reusable?
A: No – the fusible link requires replacement after activation
(kits available).
Q: Can this flow control device handle methane gas?
A: Designed exclusively for lighter gases (propane/butane).
Q: What certifications does the shutoff valve carry?
A: ATEX, ISO 9001, and RoHS compliance.
Q: How to maintain the corrosion-resistant seals?
A: Annual lubrication with silicone grease (included in maintenance
kit).
