A fire extinguisher valve is the primary operating and control mechanism housed in the neck of a portable fire extinguisher. It is a high-pressure assembly designed to securely contain the extinguishing agent and propellant until activated. When the safety pin is removed and the actuator (lever or button) is engaged, the valve opens, allowing the pressurized agent to flow through the dip tube and out the discharge hose or horn. Its design ensures controlled, rapid deployment of the suppressant while maintaining a perfect seal during storage. Valves are specifically engineered for compatibility with different agent types (e.g., dry chemical, CO2, wet chemical).
Pressure-Rated Body: Manufactured from forged brass or aluminum to withstand high internal pressure and prevent ruptures.
Reliable Sealing System: Features a robust gland seal or O-ring to maintain pressure integrity and prevent agent leakage over years of storage.
Safety Pin & Tamper Seal: Includes a galvanized steel safety pin with a plastic tamper seal to prevent accidental discharge and provide visual integrity confirmation.
Agent-Specific Design: Engineered for compatibility with specific suppressants (e.g., dry chemical, CO2, foam) to ensure optimal flow and performance.
Integrated Dip Tube: Connects to a tube that extends to the bottom of the cylinder for complete agent evacuation.
Standard Threading: Features standardized threads (e.g., ½” NPT) for compatibility with discharge hoses and horns.
Portable Fire Extinguishers: The core component in ABC, BC, CO2, and wet chemical extinguishers for homes, offices, and vehicles.
Industrial Safety Systems: Used in larger extinguishers mounted in factories, warehouses, and chemical plants.
Commercial Kitchens: Integrated into Class K wet chemical extinguishers for grease fire suppression.
Marine & Automotive: Essential for fire suppression systems on boats, commercial trucks, and emergency vehicles.
