Pressure Reducing Hydrant Valves
Safe, Controlled Pressure in High-Rise Installations
Pressure surges and inconsistent flow rates can pose a serious risk during fire-fighting operations, especially in high-rise and multi-storey buildings. That’s where the William Eagles range of Pressure Reducing Hydrant Valves (PRVs) comes into play. Designed to provide safe, steady, and controlled outlet pressure, these valves ensure that hose teams can operate effectively — without the risk of sudden bursts, water hammer, or equipment strain.
These PRVs are essential components in wet riser systems, where incoming water pressure can vary significantly based on the location within the building. Without proper pressure regulation, floors closer to the inlet may experience dangerously high pressures, while higher floors may suffer from low flow. The William Eagles PRVs are engineered to balance this pressure, delivering consistent performance throughout the system and protecting personnel, hoses, and nozzles during emergency use.
Critical Safety in Demanding Applications
You’ll typically find these pressure reducing hydrant valves installed in:
- High-rise commercial and residential towers
- Hospitals and healthcare facilities with multi-floor layouts
- Shopping centres, stadiums, and airports
- Industrial plants where foam systems or high-pressure water supply is required
- Marine vessels and offshore platforms, where system pressures fluctuate with operation
Whether installed inside stairwells, service risers, or fire pump rooms, PRVs ensure operational safety for both personnel and equipment. Their role becomes especially important in fire-fighting strategies for buildings over 18 metres tall, where unmanaged static pressure can exceed safe hose operating levels.
Built to British Standards with Proven Control
The William Eagles PRV range is manufactured in accordance with BS5041-1 and BS9990, ensuring that systems meet fire safety regulations and insurance requirements. These valves are available as factory-set units for fixed-pressure applications, or adjustable models where pressure needs may vary across floors or over time. Each valve is designed for low maintenance and long service life, even in challenging environmental conditions.
Why Bronze Is the Smart Choice
Manufactured from high-quality bronze and gunmetal, these valves offer a unique advantage in environments where corrosion, moisture, or aggressive cleaning agents are present. Bronze is inherently resistant to rust and scale build-up, which can otherwise impair valve performance or cause dangerous malfunctions during emergencies.
Unlike plastic or low-grade alloys, bronze PRVs retain their reliability over years of static service, making them the ideal material for mission-critical fire protection components — especially in marine, offshore, and coastal applications. On bronzevalve.co.uk, we prioritise components that combine durability, regulatory compliance, and proven fire safety performance — and William Eagles PRVs deliver exactly that.
