Brass Variant Lockable Ball Valve And Strainer NR-L003

Spec of Brass Lockable Ball Valve with Strainer

Product Overview: 2-in-1 Valve + Strainer for Clean, Controlled Fluid Systems

The Brass Variant Lockable Ball Valve And Strainer NR-L003 combines two essential functions—fluid control and filtration—in a single, durable unit. Designed for water and non-corrosive liquids, it features an integrated strainer that removes impurities (e.g., sediment, debris) to protect downstream equipment (like pumps, faucets, or heaters) from clogs. The lockable mechanism lets users secure the valve in a flow-limited or fully closed position, preventing unauthorized adjustments (e.g., bypassing restrictions for non-payment) or tampering. Made from high-grade brass (CW617N, HPB59-1, lead-free C46500) and compliant with EN12165, EN13828, and BS21 standards, the NR-L003 is ideal for systems where clean flow and security are priorities.

Product Features: Filtration, Security, and Versatility

Integrated Strainer: Maintain Clean Fluid Flow

The built-in strainer traps sediment, rust, and other debris before they enter pipes or equipment. This reduces maintenance costs (by preventing clogs) and extends the lifespan of downstream components—such as water heaters, dishwashers, or industrial pumps. The strainer is easy to remove and clean, requiring no special tools.

Lockable Mechanism: Control Access and Flow

Unlike standard valves, the NR-L003 can be locked in a “flow-limited” position (to restrict supply without fully cutting it off) or fully closed. This is useful for utility companies (to manage non-paying customers) or property managers (to limit water use in shared spaces). Only a special key (sold separately) can unlock the valve, preventing tampering.

Premium Brass Construction: Durability and Corrosion Resistance

The valve’s brass body resists rust, oxidation, and chemical damage from non-corrosive liquids. Lead-free options (C46500, CW511L) are available for potable water systems, ensuring compliance with health regulations and safe drinking water.

Versatile Sizing and Connections: Fit Most Systems

The NR-L003 comes in 1/2” and 3/4” sizes, with threaded (BSP/NPT) connections that match standard pipes. This flexibility makes it easy to install in residential, commercial, or light industrial systems.

Applications: Systems Requiring Clean Flow and Security

The NR-L003 is ideal for:

• Residential Water Systems: Filtering sediment from municipal water before it reaches home appliances (e.g., washing machines, showers) and allowing homeowners to lock the valve during vacations.

• Commercial Buildings: Managing water flow to offices, hotels, or apartments—filtering debris to protect HVAC systems and locking valves to prevent unauthorized water use.

• Utility Companies: Regulating water supply to customers, using the flow-limited lock to address non-payment without disconnecting service entirely.

• Light Industrial Settings: Filtering non-corrosive liquids (e.g., coolants) in small manufacturing facilities, ensuring equipment remains clog-free and secure.

FAQ: Common Questions About NR-L003 Valve-Strainer Combos

How often should I clean the NR-L003’s strainer?

Clean the strainer every 3–6 months (or more frequently if you notice reduced water flow). To clean, turn off the valve, remove the strainer housing, rinse the strainer with water, and reattach it.

Does the NR-L003 come with a locking key?

No—the special key is sold separately to prevent unauthorized access. Contact the manufacturer to purchase a key that matches your valve.

Can the valve be used with hot water systems?

Yes—the NR-L003 operates safely at temperatures up to 120°C (248°F), making it suitable for hot water lines (e.g., from water heaters to sinks).
