Orbit 4-Valve Sprinkler Manifold — Heavy-Duty Preassembled 3/4"–1" UV-Resistant, Plug-and-Play

The Orbit 4-Valve Heavy Duty Preassembled Sprinkler Manifold (57257) is a ready-to-install, weatherproof manifold with four in-line valves that simplifies multi-zone irrigation setup for 3/4" and 1" systems.

This preassembled unit combines durable, UV-resistant components with plug-and-play features so you can connect a four-zone manifold to your irrigation timer and supply lines quickly. Built from high-impact materials and including L-Series in-line valves with 24 VAC solenoids, the manifold is compatible with common pipe types and smart controllers. The Easy Wire system, swivel unions, and push-to-connect compatibility reduce install time and make future maintenance straightforward.

How does this manifold speed up the installation of a four-zone system?

The manifold arrives fully assembled, so you avoid assembling individual valves and fittings in the field. Hand-tighten unions and use the Easy Wire harness to hook up your timer without pulling multiple wires individually.

• Four pre-mounted L-Series in-line valves ready for immediate connection
• Hand-tighten swivel unions provide watertight seals—no tools needed
• Easy Wire connector organizes solenoid wiring for faster timer hookup
• Includes 3/4" and 1" adapters to match common supply lines

Will this manifold work with my existing PVC or poly irrigation lines?

Yes — the manifold is designed for compatibility with both PVC and polyethylene systems. It includes adapters and supports push-to-connect fittings so you can integrate it into most irrigation layouts.

• Supplied 3/4" and 1" adapters for common pipe sizes
• Compatible with PVC-Lock and Blu-Lock push-to-connect fittings
• Swivel unions accept threaded and slip connections for flexible hookup
• Expandable design allows adding drip filters or pressure regulators

How durable is the manifold for outdoor seasonal use?

The housing and components are engineered for outdoor exposure, using UV-resistant, high-impact plastics to resist sun damage and mechanical wear. L-Series valves with internal-bleed help ensure reliable operation season after season when winterized appropriately.

• UV-resistant construction reduces material degradation from sunlight
• High-impact plastics withstand mechanical and environmental stress
• 24 VAC solenoids for consistent electromagnetic valve actuation
• Design supports routine maintenance and part replacement if needed

Can I use this with smart controllers to conserve water?

Yes — the manifold is compatible with smart irrigation controllers, including Orbit’s B-hyve line, for precise scheduling and water-saving features. Integration lets you control each zone independently to optimize run times and reduce waste.

• Works directly with B-hyve smart controllers for automated scheduling
• Zone-by-zone control supports targeted watering and conservation
• Easy Wire system simplifies connecting solenoids to smart timers
• Expandable to add pressure regulators or filters for efficient delivery

Who is this for? The Orbit 57257 manifold is built for homeowners, landscapers, and irrigation professionals who want a fast, durable way to deploy or upgrade a four-zone sprinkler system. It suits new installs and retrofit projects where compatibility with PVC or poly piping, quick wiring, and weather-resistant performance are priorities. If you need a compact, serviceable manifold that integrates with smart controllers and supports future expansion, this preassembled solution streamlines the work without sacrificing reliability.
