Reduced Bore Brass Ball Valve NR-B003

Spec of Reduced Bore brass Ball Valve

Product Overview: Compact Reduced Bore Valve for Efficient Flow Management

The Reduced Bore Brass Ball Valve NR-B003 from Raising is designed for space-constrained environments where precise flow control is needed. Its defining feature is a smaller bore (opening) than the pipe it connects to—this compact design saves space while enabling fine-tuned flow regulation. Crafted from forged brass (CW617N, HPB59-1, lead-free options), it handles 16 bar pressure (-20°C to 120°C), comes in sizes 1/2" to 4" with BSP/NPT threads, and is suitable for plumbing, industrial, and commercial systems. Whether for appliance piping or small-flow industrial processes, the NR-B003 balances space efficiency, cost savings, and reliability.

Product Features: Space-Saving, Cost-Effective, and Reliable Performance

Reduced Bore Design for Space Efficiency

The valve’s bore is smaller than standard pipe sizes, resulting in a more compact body. This makes it ideal for tight spaces like appliance interiors (e.g., refrigerators, coffee machines), cabinetry under sinks, or dense industrial piping layouts where full-bore valves would not fit.

Forged Brass Construction for Durability & Corrosion Resistance

Manufactured via forging + machining, the brass body is stronger than cast alternatives—withstanding high pressure (16 bar) and corrosion from water or non-corrosive liquids. This durability reduces replacement costs, even in high-use environments.

Precision Flow Control with Reduced Bore Advantage

The smaller bore slows fluid flow slightly, allowing for more precise adjustments. This is critical for applications like laboratory equipment, chemical dosing systems, or commercial appliances (e.g., water dispensers) where consistent, low-to-medium flow is required.

Cost-Effective Material Usage Without Compromising Quality

Reduced bore size means less brass is used in production, lowering the valve’s cost compared to full-bore options. This makes it a budget-friendly choice for projects requiring multiple valves (e.g., residential plumbing renovations or industrial batch installations).

Versatile Thread Connections for Easy Integration

With BSP and NPT threads and sizes ranging from 1/2" to 4", the NR-B003 fits most standard pipes. It integrates seamlessly into existing systems, requiring no specialized adapters for basic installations.

Applications: Ideal for Compact, High-Precision Fluid Systems

Compact Plumbing Installations (Appliances, Cabinetry)

Appliance manufacturers use the NR-B003 for built-in systems like washing machines, dishwashers, or under-sink water filters. Its compact size fits inside appliances, while precise flow control ensures optimal performance (e.g., preventing overflow in dishwashers).

Industrial Small-Flow Systems

In factories, it regulates low-to-medium flow in processes like chemical dosing, coolant circulation for small machinery, or laboratory fluid transfer. The reduced bore’s precision prevents waste of expensive chemicals or fluids.

Commercial Equipment (Coffee Machines, Water Dispensers)

Commercial appliances (e.g., espresso machines, bottleless water coolers) rely on the NR-B003 for consistent water flow. Its compact design fits inside equipment, and corrosion resistance ensures longevity in high-use commercial settings.

Residential HVAC & Water Heaters

For residential heating or hot water systems, the valve controls flow to radiators or water heaters. Its space-saving design fits in utility closets, and the brass construction withstands hot water temperatures (-20°C to 120°C) without degradation.

FAQ: Common Questions About Reduced Bore Brass Ball Valve NR-B003

What’s the difference between reduced bore and full-bore ball valves?

Reduced bore valves have a smaller opening than the pipe (for space and precision), while full-bore valves match the pipe size (for maximum flow). The NR-B003 is better for compact or precision-focused applications; full-bore valves suit high-flow needs (e.g., irrigation).

What’s the maximum size available for the NR-B003?

It ranges from 1/2" to 4"—the larger sizes (2"–4") are suitable for industrial medium-flow systems, while smaller sizes (1/2"–1") work for appliances and residential plumbing.

Can this valve handle high-pressure applications?

Yes, it operates at up to 16 bar, which covers most residential, commercial, and light industrial high-pressure needs. For ultra-high-pressure systems (e.g., industrial hydraulics), contact Raising for specialized valves.

Is the NR-B003 suitable for drinking water systems?

Lead-free brass options (C46500, CW511L) are available and safe for drinking water. Specify the lead-free material when ordering to comply with local water safety regulations.
