Teejet AA17L Manual Boom Control Valve

The TeeJet AA17L is a 3/4″ inlet/outlet valve designed for multi-boom setups. Its manual operation supports controlling up to three booms, which is ideal for farms needing straightforward, reliable shutoff without complex wiring. The compact footprint helps fit into tight engine bays or spray rigs, and the 3-boom compatibility reduces the need for multiple standalone valves. This model emphasizes simplicity, making it a practical upgrade for conventional sprayers that require dependable manual control with a clear on/off response.
TeeJet AA6B DirectoValve Manual Control Valve

The AA6B DirectoValve combines direct valve control with a rugged mounting flange and a 1/4″ NPT gauge port, enabling straightforward integration into existing systems. With a maximum working pressure around 150 PSI (10 bar), this valve supports typical field sprayers and can be ganged with other valves via a hex nipple for multi-boom configurations. Its molded-in mounting design simplifies installation, and the DirectoValve mechanism offers precise shutoff performance, which is essential for accurate spray patterns and minimizing drift.
Triple Boom Control Box w/ 244C Regulating & 3-144A Valves

This compact manual spray controller bundles a triple-boom setup with a 244C regulating valve and three 144A solenoid shutoff valves. It emphasizes a compact, integrated solution suitable for farms deploying three separate spray zones. The kit includes the necessary electrical components and wiring, enabling a streamlined installation. While it is manual, the built-in regulation and individual valve control offer consistent spray rates across booms, reducing variability and drift in field conditions.
TeeJet 744A Triple Section Boom Control w/ Harness

The TeeJet 744A offers a triple-section control, designed for use with solenoid or ball valves. This model features a liquid-filled 100 PSI pressure gauge and a night-friendly, lighted gauge for visibility in low-light conditions. It comes with heavy-duty switches that have LED indicators, making status checks easier on the farm. The 744A system is compatible with DirectoValve ball valve kits and provides a compact yet robust spray controller option for multi-boom operations.
TeeJet AA144A-1 Directo Valve, 10 GPM, 100 psi

The AA144A-1 Directo Valve is built for high-flow applications, rated at 10 GPM and 100 psi. Its stainless-steel construction offers durability in demanding spray environments and higher resistance to corrosion from agricultural chemicals. While the feature set is concise, this valve is well-suited for larger booms or systems requiring strong flow control with reliable shutoff, making it a solid choice for professional operators seeking long-term performance.
Buying Guide: Key Purchase Considerations
When selecting a sprayer boom control valve, consider the following factors to ensure the best fit for your equipment and field needs:
- Booth compatibility: Check inlet/outlet sizes (3/4″ is common) and whether the valve supports multiple booms or requires a separate manifold.
- Control type: Manual valves are simple and rugged, while DirectoValve and solenoid-equipped options add automation and multi-zone capabilities.
- Pressure rating: Match the valve’s maximum PSI to your sprayer’s operating range to avoid leakage or failure under pressure spikes.
- Mounting and installation: Look for molded mounting flanges or compact control boxes that fit your sprayer chassis or tank setup.
- Gauges and indicators: Lightweight, illuminated gauges help in low-light conditions and enable quick checks of spray pressure and status.
- Materials and durability: Stainless steel or corrosion-resistant components extend service life in chemical-rich environments.
- Electrical wiring and harnesses: For solenoid-based systems, ensure compatibility with existing harnesses and the availability of spare parts.
- Future expansion: If you anticipate adding more booms, consider valves or control boxes that can be easily ganged or expanded.
In practice, manual systems like the AA17L and AA6B deliver reliable, straightforward control with fewer maintenance needs. For farms seeking multi-zone automation and integrated regulation, the triple-section configurations with the 244C valve and 144A solenoids provide scalable options. Stainless and high-flow models such as the AA144A-1 suit larger applications where consistent flow rates are critical. Finally, the 744A line adds night visibility and robust indicators, improving operator awareness during late-day operations. These factors collectively influence long-term efficiency, spray accuracy, and labor costs on the farm.
