These valves are typically constructed from heavy-duty brass or bronze to provide durability and corrosion resistance. They are often installed in fire hydrant boxes, on wet risers, or used with fire hose rack assemblies.
A fire hose angle valve is a specialized globe-style valve designed for reliability and high-pressure environments.
- Construction: Most are cast from high-grade brass or bronze to prevent rust and corrosion, ensuring the valve remains functional even after years of inactivity.
- Mechanism: It features a 90-degree "angle" design for easy hose attachment in tight spaces. The red handwheel allows firefighters to manually open or close the valve to regulate water flow.
- Pressure Management: Some versions are Pressure Restricting Valves (PRVs), which include an internal mechanism to limit the discharge pressure. This protects firefighters from the dangerous recoil of high-pressure water lines.
- Standards: Professional models are typically UL Listed and FM Approved, meaning they meet strict safety and performance benchmarks (like NFPA 13) for fire safety equipment.
- Specifications: They usually come in standard sizes like 1.5" or 2.5" and are often rated for working pressures up to 300 PSI.
