The Brass Angle Water Meter Lockable Ball Valve NR-L005, designed by Raising—a 20+ year ISO 9001-certified manufacturer—is a premium fluid control solution tailored for water meter systems. Crafted from high-grade brass (including CW617N, HPB59-1, DZR CW602N, and lead-free options like C46500/CW511L), this valve merges durability with security in a compact angle design. It operates efficiently under 16 bar working pressure and a temperature range of -20℃ to 120℃, making it suitable for both cold and hot water applications. Equipped with a lockable mechanism and double NBR O-ring sealing, it prevents unauthorized tampering, fraud, or accidental adjustments—critical for maintaining accurate water metering and supply control. Its thread connections (BSP/NPT) and size options (DN15x3/4"×25mm, DN15x3/4"x32mm) ensure compatibility with most residential and industrial piping layouts, aligning with EN12165, EN13828, and BS21 industry standards for reliability.
The valve’s brass material offers exceptional corrosion resistance, pressure tolerance, and wear resistance. This ensures stable operation over years of use, even in harsh water conditions, reducing the need for frequent replacements and lowering maintenance costs. Lead-free brass variants also meet safety standards for potable water systems, making it ideal for residential use.
A core differentiator, the lockable design allows the valve to be secured in open, closed, or flow-limiting positions. This feature is vital for preventing water theft (by blocking meter removal) or unauthorized flow adjustments—especially useful for utility companies dealing with non-payment scenarios, as it restricts supply without fully cutting off water to subscribers. Only a special key can unlock the valve, adding an extra layer of security.
Unlike straight valves, the angle configuration adapts to tight installation spaces and diverse pipeline layouts. It eliminates the need for additional fittings to change flow direction, simplifying setup and reducing stress on connected pipes. This flexibility makes it suitable for both new installations and retrofits in residential basements, industrial utility rooms, or commercial water meter closets.
Double NBR O-rings ensure a leak-tight seal, minimizing water waste and maintaining system efficiency. The valve complies with strict EN12165, EN13828, and BS21 standards, guaranteeing compatibility with global plumbing systems and meeting safety requirements for both residential and industrial use.
In homes, the NR-L005 secures water meter connections, preventing tampering that could lead to inaccurate billing. Its lead-free brass option is safe for potable water, and the angle design fits in small utility spaces (e.g., under sinks or in basements).
For light industrial settings (e.g., manufacturing plants, workshops), the valve regulates water flow to equipment while resisting corrosion from non-corrosive liquids. The lockable feature ensures only authorized personnel adjust flow, preventing operational disruptions.
Utility companies use the NR-L005 in municipal water networks to manage supply to neighborhoods. The flow-limiting lock function helps address non-payment issues without fully disconnecting households, maintaining essential water access.
In offices, hotels, or retail spaces, the valve controls water flow to meter banks, ensuring accurate consumption tracking and preventing unauthorized use (e.g., by tenants bypassing meters).
It is designed for water and non-corrosive liquids. It is safe for potable water (especially lead-free brass variants) and works with industrial non-corrosive fluids like coolants or mild detergents.
Contact Raising’s customer support with your valve model and purchase details. Raising provides replacement keys for authorized users (e.g., homeowners, utility companies) to ensure secure access without damaging the valve.
Yes, the BSP/NPT thread connections are standard, so most DIY users can install it with basic plumbing tools. However, for municipal or industrial installations, professional setup is recommended to ensure compliance with local codes.
The brass construction resists cracking in temperatures as low as -20℃, but it is recommended to drain the valve if exposed to prolonged freezing (below -20℃) to prevent damage from expanding ice.
Minimal maintenance is needed. Inspect the NBR O-rings annually for wear and replace if leaking. The brass body can be cleaned with mild soap and water to remove sediment, ensuring long-term performance.
