The NDS 321BCB is a professional-grade irrigation valve box designed to house and protect ICV-style irrigation control valves in underground installations. Built for durability in field conditions, this valve box measures 13 inches wide by 24 inches long with a 12-inch depth, providing ample interior space for single or ganged valve assemblies. The green lid blends with turf and landscape environments, making it a common choice for both residential and commercial irrigation systems. Licensed irrigation contractors and landscape professionals install this box in new construction and retrofit applications where reliable valve access is required.
This valve box is suited for in-ground irrigation system installations where ICV-style valves need protection from soil, debris, and physical damage. It fits typical residential lawn systems as well as larger commercial landscape zones where deeper valve setups are required. The 12-inch depth accommodates valve bodies, solenoids, and associated fittings without crowding. Its professional classification indicates a heavier construction than residential-grade boxes, making it appropriate for high-traffic turf areas and municipal landscape applications.
Designed as an OEM-style enclosure for ICV-type irrigation control valves in residential and commercial underground irrigation systems.
Installation is typically performed by licensed irrigation contractors or landscape professionals. Excavate to the appropriate depth to allow the valve box rim to sit flush with or just above grade, and ensure adequate drainage at the base of the excavation. Power down and depressurize the irrigation system before working on any valve components housed inside the box. Follow all applicable local irrigation and plumbing codes during installation.
