High-Temp One Inch Lighter Gas Valve for Furnace Pilot Lines and Oven Ignition with Extended Bonnet and
Graphite Packing
Product Description:
Withstand intense radiant heat with this High-Temp One Inch Lighter Gas Valve, purpose-built for applications near furnaces, kilns, ovens, and
other high-temperature equipment where standard valves fail. Its
key feature is an extended bonnet design, which distances the critical stem seals and operating
mechanism from the primary heat source flowing through the one inch gas line. Sealing integrity under heat is ensured by high-temperature graphite packing, capable of sustained operation well above the limits of standard
PTFE seals. The valve body and critical components are constructed
from heat-resistant materials. This specialized gas isolation valve utilizes a robust ball valve core for reliable positive shut-off of the lighter gas supply, operated via a sturdy lever handle designed to remain cool to the
touch. Ensure safe and dependable pilot gas control in the most
thermally challenging environments surrounding your combustion
Bullet points:
Extended bonnet protects seals and stem from high ambient/radiant heat.
High-temperature graphite packing ensures sealing integrity under extreme heat.
Robust ball valve core for positive shut-off in the lighter gas supply.
Constructed with heat-resistant materials for furnace/oven
proximity.
Essential gas isolation valve for one inch pilot lines in high-heat zones.
Specific application scenario:
Isolating the pilot gas feed for a burner located inside a
high-temperature industrial ceramic kiln, where ambient
temperatures near the valve can exceed 300°F (150°C).

FAQ:
Q: What is the maximum continuous operating temperature for this
high-temp lighter gas valve?
A: Standard models are rated for up to 450°F (232°C) ambient
temperature at the bonnet, with higher ratings available. Confirm
your specific temperature requirement.
Q: Why is graphite packing used instead of PTFE?
A: Graphite retains its sealing properties and resilience at much
higher temperatures (up to 1000°F+ in inert atmospheres) where PTFE
would degrade or melt.
Q: Does the extended bonnet affect the flow capacity of the one
inch gas valve?
A: No, the flow path through the ball and body remains full port
one inch. The bonnet extension is external to the flow path.
Q: Can this valve handle direct flame impingement?
A: No. The extended bonnet protects against high ambient/radiant
heat, but direct flame contact will damage the valve. Ensure proper
location and shielding.
Q: Is the lever handle also heat-resistant?
A: Yes, handles are typically made of high-temp engineered polymer
or metal with an insulated sleeve to remain operable in hot
environments.
