The Lead-Free Bronze Corporation Stops NR-S011 is a critical component for residential and commercial water systems, designed to act as an “emergency shut-off switch” where a property’s water line connects to the city main. Crafted from high-quality lead-free bronze, this valve eliminates the risk of lead contamination in drinking water, aligning with modern health and safety standards. It features a durable construction that withstands underground conditions—including wet dirt and temperature fluctuations—while ensuring secure, leak-free connections via flare copper tube nuts and either CC taper threads or NPT threads. Compliant with AWWA Standard C800, ASTM B-62, and ASTM B-584, the NR-S011 is built to outlast most plumbing components, making it a reliable choice for long-term water system control.
The NR-S011 uses lead-free bronze alloys (including C83600, C84400, C89833, and C87850) to ensure 100% safety for drinking water. This eliminates the risk of lead leaching, a common concern with older brass or bronze valves, and meets strict regulations for potable water systems worldwide.
Bronze’s natural resistance to rust and corrosion makes the NR-S011 perfect for buried applications. Unlike plastic or steel valves that degrade over time in moist soil, this bronze valve maintains structural integrity even after years of underground exposure, reducing maintenance and replacement costs.
A long T-handle wrench (easily inserted through standard access holes) allows users to twist the valve open or closed without digging up the yard. This design is critical for emergency scenarios—such as burst pipes—where quick water shut-off is needed to minimize damage.
The valve offers two connection options: flare copper tube nut paired with either CC taper thread or NPT thread. This flexibility ensures compatibility with most residential and commercial piping setups, simplifying installation for plumbers and utility workers.
The NR-S011 is primarily used in:
• Residential Properties: Installed under metal access lids near the street to control water flow to homes, enabling homeowners or plumbers to shut off water without accessing the city’s main line.
• Commercial Buildings: Used in offices, retail spaces, and apartment complexes to manage water supply to individual units or the entire building, supporting routine maintenance or emergency repairs.
• Municipal Projects: Integrated into water distribution systems to provide localized shut-off points, reducing service disruptions when repairing or upgrading property lines.
The valve operates reliably between -20°C to 120°C (-4°F to 248°F) and handles a maximum working pressure of 16 bar (232 psi). This range covers most climate conditions and standard water system pressures.
No—standard plumbing tools (such as wrenches for thread tightening) are sufficient for installation. The T-handle wrench for operation is widely available at hardware stores, and no specialized equipment is needed.
