Give your irrigation valve the protection it needs with the 6 in. Round Valve Box and cover. Fits over your irrigation components to conceal and prevent damage or tampering, and provides a clean and safe environment with access for maintenance. The valve box is engineered with features that provide durability and convenience. Here's what's built into every box. The durable 6 in. round valve box and cover are built with structural reinforcing ribs to protect fixtures from the elements, pedestrian traffic, lawn care equipment, and potential vandalism. Fits over a single valve or irrigation accessories. The round black valve box includes a pipe hole for irrigation pipe connections. The green irrigation control valve (ICV) cover overlaps the valve box to prevent dirt and debris from entering. The snap-in lid features a finger hole, making it easy to lift for maintenance. The valve box is made of polypropylene (PP) using 100% recycled material; cover is also made of polypropylene (PP) using a combination of recycled and virgin content. The box and cover are treated with UV inhibitors to prevent fading and cracking due to sun exposure.
