Orbit 3/4-Inch Brass Automatic Anti-Siphon Valve 57065 — 24VAC Solenoid & Adjustable Flow

Orbit 57065 is a 3/4-inch brass automatic anti-siphon irrigation valve that prevents backflow and gives adjustable flow control for above-ground sprinkler zones. The Orbit 57065 anti-siphon valve combines a durable brass body, an atmospheric vacuum breaker and a 24 VAC solenoid to protect potable water while managing irrigation flow. Built for above-ground riser installation, this valve is suited to residential sprinkler systems and contractors who need a dependable backflow prevention device that’s compatible with common controllers and simple to maintain.

How does this valve stop contaminated water from entering my home supply?

The Orbit anti-siphon valve uses an internal atmospheric vacuum breaker (AVB) and a poppet design that closes automatically when water pressure drops. That creates a physical barrier against siphoning and backflow, protecting the potable water system without additional external backflow assemblies in many jurisdictions.

• Atmospheric vacuum breaker opens to vent and prevents suction when pressure drops
• Poppet mechanism seals reliably when the valve shuts off
• Brass construction resists corrosion for long-term performance

What installation and maintenance steps should I expect?

This valve is intended for above-ground installation on a riser, at least 6 inches above the highest sprinkler head in the zone. The unit includes an internal scrubber filter to reduce clogging and PVC-Lock-compatible connections for fast, glue-free assembly.

• Install on a riser, minimum 6" above highest head per typical AVB requirements
• Use PVC-Lock fittings for quick connection without solvent welding
• Clean or replace the internal scrubber filter during seasonal maintenance

Which controllers and irrigation setups is the Orbit valve compatible with?

The valve operates on a standard 24 VAC solenoid and works with most residential irrigation controllers that supply 24 VAC. It also features manual actuation for on-site control, plus integrated flow adjustment to fine-tune zone performance.

• Compatible with major 24 VAC irrigation controllers
• Manual lever allows immediate manual opening or shutoff
• Integrated flow control dial for balancing sprinkler output

Can this valve be used in climates with freezing temperatures?

The Orbit AVB is designed for outdoor irrigation with cold water only and must be installed above ground; it is not frost-proof. In regions that freeze, the valve should be drained and removed or otherwise winterized to avoid freeze damage.

• Designed for outdoor, cold-water irrigation use only
• Not rated as freeze-resistant—drain or winterize in freezing climates
• Easy disassembly for off-season storage or servicing

Who is this for? The Orbit 57065 is intended for homeowners, landscapers and irrigation professionals who need a compact, reliable above-ground anti-siphon valve with adjustable flow and broad controller compatibility. If you want a brass, long-lasting valve that simplifies installation, prevents backflow without complex external assemblies, and integrates with standard 24 VAC controllers, this model is a practical choice. For water-conservation-minded users, pairing the valve with smart controllers such as B-hyve will help optimize runtime and reduce waste.
