Description
The Badger 18672B Valve Stem is a critical internal component specifically designed for Halon 1211 fire extinguishers. It functions as the primary mechanism that, when depressed by the operating lever, allows the extinguishing agent to discharge, and automatically reseals the unit when the lever is released.
Technical Description
The valve stem is an OEM (Original Equipment Manufacturer) replacement part essential for maintaining the pressure seal and operational readiness of handheld extinguishers.
- Primary Application: Exclusively for Badger Halon fire extinguishers.
- Compatibility: While primarily for Halon units, it is often grouped with Buckeye Halon valve stems in professional parts catalogs due to similar specifications.
- Function: It serves as the moving core within the valve assembly, working in conjunction with an internal spring to stop agent flow once the handle is released.
Maintenance & Replacement
Because it is the most frequently replaced component in a valve assembly, professionals recommend keeping them in stock to prevent “leakers”.
- Replacement Intervals: Standard service manuals require replacement during a full “tear-down,” during hydrostatic testing, or whenever damage or leakage is detected.
- Safety Criticality: It is vital to use the exact part number (18672B) for Halon models, as using an incorrect valve stem (such as those meant for dry chemical or water units) will prevent the extinguisher from functioning correctly or holding pressure.
