Built for maximum firefighting power, this Large-Bore Heavy-Duty Male Fire Extinguisher Valve is the heart of large wheeled fire extinguishers. Designed to handle the high-volume flow of extinguishing agents from 50kg to 150kg units, this robust valve assembly features an oversized bore to minimize pressure drop and enable a powerful, sustained discharge. The valve is operated by a large, easy-to-turn handwheel, providing the control needed to manage the significant force of a fully charged unit. The reinforced outlet valve is threaded to accept a large-diameter, high-pressure hose with a robust nozzle. This male thread valve is engineered for industrial settings like petrochemical plants, airports, and warehouse facilities, where a portable, high-capacity firefighting solution is a critical first line of defense.
Bullet Points:
-
Oversized bore design for high-volume agent flow from wheeled extinguishers.
-
Reinforced outlet valve with heavy-duty threads for large-diameter hoses.
-
Large, ergonomic handwheel for positive control under high discharge forces.
-
Built as a robust valve assembly to withstand rough handling and harsh conditions.
-
The high-capacity male thread valve for industrial-grade wheeled fire units.
Specific Application Scenario
This valve is mounted on a 100kg ABC dry chemical wheeled extinguisher stationed at the entrance of a flammable liquids storage warehouse, ready to tackle a significant Class B fire.
Factory Production Floor
These valves are manufactured on a heavy-duty line. Components are forged and machined to withstand higher stresses. Each valve undergoes a high-flow test to ensure it can deliver the required agent volume without failure.
Packing and Transportation
Due to their size and weight, these valves are individually packed in heavy-duty, wooden crates with custom foam cushioning to protect them during shipping.
FAQ
-
Q: What is the thread size on the outlet valve of this heavy-duty unit?
A: It typically features a 1-inch or 1.25-inch NPT male thread to accommodate the large hoses used on wheeled extinguishers.
-
Q: How does the valve assembly handle the high recoil force during discharge?
A: It is constructed with a reinforced body and is mounted directly to a sturdy valve guard on the extinguisher, distributing the forces safely.
-
Q: Is this male thread valve suitable for foam concentrate wheeled extinguishers?
A: Yes, its materials are fully compatible with foam concentrates, and the large bore is ideal for the viscous liquid.
-
Q: What is the operating pressure for this high-capacity valve?
A: It is rated for the same standard working pressure as smaller units (e.g., 25 Bar) but is built with a much higher safety factor to handle the greater mechanical loads.
-
Q: Can the handwheel be replaced with a lever for faster operation?
A: For specific OEM customers, we can customize the actuation method to include a quick-action lever.
