NDS 117BC 15×22 Rectangular Valve Box
The NDS 117BC is a large rectangular valve box designed to shelter irrigation fixtures such as valves and control zone kits. Its 12-inch height provides ample space for multiple components, while the black box and green overlapping lid deliver a rugged, weather-resistant enclosure. The design emphasizes easy access for maintenance and ICV lettering for quick identification, helping crews locate the system underground without disruption. Structural reinforcing ribs boost durability, protecting the contents from incidental impacts and environmental wear.
NDS 107BC 6×9 Rectangular Valve Box
The NDS 107BC is a compact option featuring a 9-inch tall design suitable for narrower setups. It protects irrigation components from weather, pedestrian traffic, lawn care activities, and potential vandalism, with ICV lettering on the cover to identify designated areas quickly. Reinforcing ribs add structural strength to resist damage and ensure long-term performance, making it a practical choice for tight spaces where reliability matters most.
NDS 113BC1PK 14×19 Standard Series Valve Box
The NDS 113BC1PK belongs to the standard series and offers a balanced footprint for medium-to-large irrigation systems. It includes ICV lettering on the lid and a green overlapping cover for weather protection. The box is designed to shelter irrigation components while maintaining easy underground access for routine maintenance. Reinforcing ribs contribute to durability against external forces, and the overall construction aims to resist fading and cracking over time when exposed to UV and elements.
Rain Bird CPVBSTDEXT Professional Extension Box
The Rain Bird CPVBSTDEXT is a professional-grade extension that increases the height of compatible valve boxes by 6 inches, or can serve as a standalone 6-inch box. It’s designed to protect up to four electric or manual valves and is manufactured in the U.S.A. with 100% recycled materials, balancing performance with sustainability. This extension is suited for larger valve configurations where additional clearance is beneficial for service and wiring routing.
Underhill VersaLid 6–7 Inch Universal Cover
The Underhill VersaLid offers a universal lid suitable for 6-inch to 7-inch round valve boxes, supporting residential and commercial irrigation systems. Available in green, it features a stepped locking system and a T-top design to minimize dirt intrusion. The lid is constructed for increased top-load strength and greater sun resistance compared with some structural foam alternatives, enhancing longevity in outdoor settings and reducing maintenance needs over time.
NDS 113BC 14×19 Standard Series Valve Box
The NDS 113BC 14×19 Standard Series model provides a robust option for drainage integration with irrigation control hardware. It features a durable polystyrene body treated with UV inhibitors to prevent fading and cracking. The box has a substantial open surface area for airflow and accessibility, with a recommended load rating for medium-duty traffic when properly installed. The design supports integration with downstream drainage solutions while keeping underground components protected from the elements.
Buying Guide: Key Considerations For Choosing A Valve Box
When selecting a valve box, consider size, material, and compatibility with your irrigation layout. For larger valve configurations or multi-valve kits, rectangular boxes with added height can simplify access and maintenance. For smaller systems, compact boxes ensure space efficiency without compromising protection. Materials vary from rigid plastics to reinforced composites, each delivering different levels of UV resistance and impact tolerance. Look for features like ICV lettering for easy valve identification, reinforcing ribs for durability, and secure lids that resist dirt intrusion.
Installation considerations include alignment with existing risers and the availability of a catch basin or drain connections if you plan to route excess water. If your system sits in high-traffic areas, a lid with higher top-load strength and weather sealing can reduce wear and vandalism risk. For environments with harsh sun exposure, UV-stabilized plastics help preserve color and structural integrity. Finally, sustainability preferences may steer you toward lids and boxes manufactured with recycled materials, especially for projects aiming at LEED or green building standards.
