Single Way Underground Fire Hydrant Valve – Low-Pressure Control

The Single Way Underground Valve (SWUGV-01) is a heavy-duty, low-pressure fire hydrant valve engineered specifically for underground fire protection systems and water distribution networks requiring secure and durable installations. Constructed with a high-grade cast iron body, the valve delivers exceptional strength and resilience for long-term underground service, while precision-engineered brass couplings ensure reliable and leak-proof connectivity. The grey cast iron handwheel (BS EN 1561) with protective black coating enhances operational durability, and the red powder-coated exterior finish improves corrosion resistance in harsh subsurface environments. Designed for performance efficiency, the valve operates at nominal pressure up to 12 bar and supports maximum service temperatures up to 70°C, making it suitable for fire protection and liquid handling applications. It features a 2.5″ brass outlet conforming to BS 750 London round thread standards and a 3″ flange inlet (150 Class, 152 PCD) for standardized installation compatibility. Maintenance is simplified through replaceable gland seals that allow servicing under pressure and a replaceable rubber disc facing, reducing downtime and extending operational life. Its tamper-resistant underground configuration ensures dependable performance across municipal hydrant networks, industrial facilities, utility infrastructures, warehouses, and emergency fire protection systems. ✅
