Resideo NK300S-100 Valve
The Resideo NK300S-100 Valve is a professional-grade boiler feed combination valve designed for rapid system commissioning and robust backflow protection in closed-loop hydronic heating systems. This high-capacity 16 GPM unit integrates a testable double check backflow preventer, an adjustable pressure reducing valve, and dual shut-off ball valves into a single brass housing. Built for high-demand residential and light commercial applications, the Resideo Braukmann NK300S-100 maintains a precise 15 PSI factory-set outlet pressure, adjustable from 10 to 58 PSI, ensuring steady system pressure regardless of inlet fluctuations. The inclusion of an integrated 200-micron strainer and three accessible test ports facilitates routine NFPA or local code inspections without requiring full system drainage. This all-in-one solution streamlines the boiler fill valve installation process by reducing potential leak points and minimizing the physical footprint of the mechanical room piping.
Key Benefits
- High-Flow Performance: Delivers a 16 GPM flow rate @ 22 PSI pressure fall-off, allowing for fast fill technology during initial system startup and refilling.
- Potable Water Protection: Features an ASSE 1081 certified double check backflow preventer with an air vent to prevent heating water from contaminating the supply line.
- Simplified Maintenance: Fully replaceable cartridge and valve inserts allow for field servicing without removing the brass body from the line.
- Installation Versatility: Equipped with 1/2-inch sweat and NPT threaded connections to accommodate various piping requirements on the job site.
- Precision Monitoring: Includes an onboard 0-60 PSI pressure gauge for real-time monitoring of regulated system pressure.
Common Questions
Can the NK300S-100 be installed in any orientation?
Technicians must install this valve in horizontal pipework with the discharge connection facing downward to ensure proper operation of the atmospheric vent.
Is a separate strainer required for this boiler feed valve?
No, the Resideo NK300S-100 features an internal stainless steel fine filter mesh that protects the regulator and boiler components from sediment and welding beads.
How do I handle inlet pressure fluctuations?
The valve utilizes force-balanced technology, meaning fluctuations in supply pressure do not impact the consistency of the downstream boiler pressure.
