Brass One-piece Lockable Ball Valve NR-L004

Brass One-piece Lockable Ball Valve Technical Data Sheet 

Product Overview: Tamper-Proof Valve for Critical Flow Management

The Brass One-Piece Lockable Ball Valve NR-L004 combines compact design with enhanced security, making it ideal for applications where unauthorized valve operation poses risks. Its one-piece brass construction eliminates potential leak points (common in multi-piece valves) and simplifies installation, while the lockable feature lets users secure the valve in open or closed positions—preventing tampering, fraud, or accidental adjustments. Made from high-grade brass (CW617N, HPB59-1, DZR CW602N) and nickel-plated for extra corrosion resistance, the NR-L004 meets EN12165, EN13828, and BS21 standards, ensuring reliable performance for water and non-corrosive liquid systems.

Product Features: Security, Compactness, and Durability

Lockable Mechanism: Prevent Unauthorized Access

The NR-L004’s lockable design allows users to attach a padlock (not included) to secure the valve in open or closed positions. This is critical for sensitive settings—such as utility meters, industrial equipment, or public buildings—where tampering could lead to water waste, system damage, or safety hazards.

One-Piece Construction: Minimize Leaks and Save Space

Unlike multi-piece valves that require gaskets or seals (which degrade over time), the NR-L004’s one-piece brass body has no internal joints. This reduces leak risks and creates a compact footprint, making it ideal for tight spaces (like under sinks or in utility closets).

Nickel-Plated Body: Enhanced Corrosion Resistance

The valve’s nickel-plated exterior adds a protective layer against moisture, chemicals, and environmental wear. This extends the valve’s lifespan, even in humid or corrosive environments (such as basements or industrial facilities).

Smooth Operation: Reliable Flow Control

The brass ball inside the valve rotates smoothly, ensuring precise flow regulation and a tight seal when closed. The 3/4”x3/4” size and threaded (BSP/NPT) connections fit standard pipes, making it easy to integrate into existing systems.

Applications: Sensitive and Space-Constrained Environments

The NR-L004 is widely used in:

• Utility Systems: Securing water meters to prevent tampering (e.g., unauthorized water use to avoid bills) or accidental shut-off that disrupts service.

• Industrial Facilities: Controlling fluid flow to machinery or production lines, where unauthorized adjustments could halt operations or cause equipment damage.

• Public Buildings: Installed in schools, hospitals, or government facilities to ensure critical systems (like fire sprinklers or medical equipment water lines) remain in the correct position.

• Residential Complexes: Regulating water flow to individual units, allowing property managers to secure valves during maintenance or tenant turnovers.

FAQ: Common Questions About NR-L004 Lockable Valves

What type of padlock works with the NR-L004’s lockable feature?

Most standard padlocks (with a shackle diameter of 5mm or less) are compatible. The valve has a built-in loop for padlock attachment, and no special adapters are needed.

Is the NR-L004 suitable for outdoor use?

Yes—the nickel-plated body and brass construction resist rust and weather damage. However, we recommend covering the valve with a protective housing in extreme climates (e.g., heavy rain or snow) to extend its lifespan.

Can the valve be locked in both open and closed positions?

Absolutely—you can secure the NR-L004 in either position. This flexibility is useful for scenarios like locking a fire sprinkler line open (to ensure constant water flow) or locking a non-essential line closed (to prevent waste).
