Rainbird Standard Valve Box 22" x 17" x 12"

Rain Bird VBSTD – Standard Valve Box Specifications

What fits inside the Rain Bird Standard Valve Box?
The VBSTD is sized to comfortably house one or more standard irrigation solenoid valves, along with associated wiring connections, waterproof wire connectors, inline filters, and pressure regulators. Its 21.8" × 16.6" × 12" interior provides ample room for multi-valve manifold assemblies in typical residential irrigation setups. DripWorks carries a full range of compatible irrigation valves to use with this box.

Is the body made from virgin or recycled plastic?
The VBSTD body is manufactured from 100% recycled plastic materials, making it an earth-friendly choice for irrigation projects pursuing LEED certification or sustainability credits. Despite being made from recycled content, it delivers full structural performance — the corrugated sides and wide flange base provide excellent compression resistance under heavy surface loads.

Why does the lid have no holes?
Rain Bird's "smart lid" design eliminates the open holes found on older valve box lids. These holes were common access points for pests such as insects and rodents, as well as pathways for soil and debris to pack into the box around your valves and wiring. A solid lid keeps the interior clean and pest-free, reducing the likelihood of damage to wiring insulation and valve components over time.

What are the pipe knockout features?
Pre-formed pipe-hole knockouts are built into the sides of the box and are sized to fit most standard irrigation pipe configurations — including common PVC lateral pipe sizes. This eliminates the need for field cutting with a saw or knife. After routing your pipe through the knockout, you can slide the knockout piece back into place to close the gap around the pipe and keep backfill soil from entering the box.

Can I stack or extend this valve box for deeper installations?
Yes. The VBSTD supports bottom-to-bottom stacking with compatible Rain Bird extension models, allowing you to increase the burial depth for deep installations without switching to a different box series. This is useful in areas with significant frost depth requirements or where valves must be buried deeper to avoid surface damage.

Will this box hold up under vehicle or lawn equipment traffic?
The corrugated side walls and wide flange base are designed to provide strong compression resistance and structural stability. The beveled lid edges also help prevent the lid from being sheared off or cracked by mower decks and edgers. For areas subject to vehicle traffic, however, it is best practice to install a concrete collar around the box for added support.

What type of valves work with this box?
The VBSTD is compatible with virtually any standard irrigation solenoid valve — both AC-powered (electronic) and battery-operated DC valves. It can also house automatic distribution valves for drip irrigation manifolds. The box is brand-agnostic — it works with Rain Bird, Hunter, Orbit, and other standard valve brands.

Is this valve box LEED compliant?
Yes. Because the body is manufactured entirely from recycled plastic materials, the VBSTD qualifies for recycled content credit points in LEED (Leadership in Energy and Environmental Design) certified projects. This makes it an excellent choice for commercial landscape and irrigation installations where green building credits are a priority.

How deep should I bury the valve box?
The top of the lid should typically be flush with or just slightly below grade to allow easy access. In cold-weather climates, valves should be buried deep enough that they won't freeze — generally below your local frost line. The 12" depth of the VBSTD accommodates most residential installation needs. If additional depth is required, stackable extension models are available.
