The NDS 313C is a professional-grade replacement lid designed for use with NDS irrigation and drainage valve boxes. Measuring 14 x 19 inches overall with an 11 x 17 inch opening dimension, this lid provides secure, ground-level access to valve components while blending into turf and landscaping with its green finish. It is installed by irrigation contractors, landscape professionals, and plumbing technicians who require reliable, weather-resistant access covers for below-grade valve and control systems.
This lid is suited for residential and light commercial irrigation installations where a durable, low-profile valve box cover is needed. It fits NDS ICV-series valve boxes and is a direct replacement for worn, cracked, or missing lids on existing installations. The green colorway is a standard field choice for minimizing visual impact in lawn and landscape applications.
Designed as an OEM-style replacement lid for NDS ICV-series valve boxes requiring a 14 x 19 inch cover with an 11 x 17 inch opening.
Installation is performed by irrigation technicians or landscape contractors. Shut off the irrigation system and relieve any pressure at the valve before removing or replacing the lid. Ensure the valve box rim is clean and free of debris so the lid seats flush and does not rock. No special tools are required for lid replacement.
