Brass angle lockable ball valve NR-L020

Spec of Brass angle  lockable ball valve

Product Overview: Space-Saving Brass Valve for Secure Fluid Regulation

The Brass Angle Lockable Ball Valve NR-L020, a flagship product from Raising Valve, is a compact and secure fluid control solution designed for tight spaces and anti-tampering needs. Crafted from high-grade brass (CW617N, HPB59-1, DZR CW602N, lead-free C46500/CW511L), this valve offers durability, corrosion resistance, and compatibility with water and non-corrosive liquids. It operates at 16 bar working pressure and -20℃ to 120℃, making it suitable for diverse environments. The angle design saves space in tight installations, while the lockable handle prevents unauthorized access. Available in sizes DN15X3/4"X3/4" and DN15X3/4"X1/2" with BSP/NPT threads and compression ends, it complies with EN12165, EN13828, and BS21 standards—ideal for residential, commercial, and industrial use.

Product Features: Space Efficiency, Security, and Precision Control

Compact Angle Design for Tight Installations

The angle configuration eliminates the need for extra fittings (e.g., elbows) to change flow direction, making it perfect for small spaces like under-sink cabinets, utility closets, or industrial equipment enclosures. It fits easily between existing pipes, reducing installation complexity and saving space for other components.

Lockable Handle for Tamper-Proof Operation

The valve’s handle can be locked in open, closed, or partial positions using a standard padlock (not included)—a simple yet effective security feature. This prevents unauthorized adjustments (e.g., water theft, accidental shutdowns) and is ideal for utility companies, commercial buildings, or industrial facilities where access control is critical.

Premium Brass Construction for Durability

Brass offers exceptional corrosion resistance, pressure tolerance, and wear resistance—ensuring the valve performs reliably for years. Lead-free brass variants meet potable water standards (e.g., NSF/ANSI 61), making it safe for drinking water lines. DZR brass options provide extra protection against outdoor or high-humidity corrosion.

Dual Connection Options (Threads + Compression Ends)

A key differentiator, the NR-L020 offers both BSP/NPT threads and compression ends—compatible with PE, PEX, copper, and galvanized pipes. This versatility eliminates the need for adapters, making it suitable for new installations and retrofits (e.g., upgrading old galvanized pipes to PEX).

Precise Ball Valve Mechanism

The ball valve design enables quick on/off operation and precise flow adjustment. This is critical for applications like industrial fluid control (regulating coolant pressure) or residential plumbing (adjusting hot water flow to showers), ensuring optimal performance and resource savings.

Applications: Residential Plumbing, Commercial, Industrial, and Municipal

Residential Under-Sink Plumbing

Homeowners use the NR-L020 under kitchen or bathroom sinks to control water flow to faucets. The compact angle design fits in tight cabinet spaces, and the lockable handle prevents children from turning off water. The lead-free brass option is safe for drinking water.

Commercial Building Utility Systems

In offices, schools, or hospitals, the valve controls water flow to restrooms, kitchens, or cleaning stations. The lockable handle ensures only maintenance staff can adjust flow, preventing misuse (e.g., excessive water waste), and the dual connections work with the building’s existing pipe materials.

Industrial Fluid Control

In manufacturing or automotive facilities, the valve regulates non-corrosive fluids (e.g., coolants, lubricants). The brass body resists industrial contaminants, and the precise flow control ensures equipment operates efficiently. The lockable handle prevents unauthorized adjustments that could cause machinery damage.

Municipal Water Meter Stations

Municipalities use the NR-L020 in meter stations to control water supply to neighborhoods. The angle design fits in small meter boxes, and the lockable handle prevents tampering. The compression ends simplify connection to municipal PE pipes, reducing installation time.

FAQ: Common Questions About NR-L020

What type of padlock works with the lockable handle?

Any standard padlock with a 5mm to 8mm shackle will fit. Choose a weather-resistant padlock (e.g., stainless steel) for outdoor or high-humidity installations.

Can the valve be used for gas applications?

No, the NR-L020 is designed for liquids (water and non-corrosive fluids) only. For gas, use Raising’s dedicated brass gas valves (e.g., NR-G001).

How do I maintain the compression ends?

Inspect the compression rings annually for wear. If leaking occurs, turn off the water, loosen the compression nut, replace the ring, and retighten. Use only Raising-approved replacement rings for optimal performance.

Is the valve compatible with hot water heaters?

Yes, it operates safely up to 120℃—suitable for connecting to electric or gas water heaters. Use the compression ends for PE/PEX pipes or threads for copper pipes.

Does Raising offer technical support for installation?

Yes, Raising provides a detailed installation guide with the valve. For complex projects (e.g., industrial retrofits), contact their technical team via email or phone for step-by-step assistance.
