Description
If you’ve ever had chemicals drip from your boom nozzles after shutting off the sprayer, you know the headache it causes—uneven application, wasted product, and contaminated areas where you don’t want it. A good check valve stops that backflow and keeps your spray where it belongs. This stainless steel unit is built to handle whatever chemicals you’re running while keeping your spray system working like it should.
What You’re Getting
- Reliable 10 PSI activation prevents dripping while allowing proper flow during spraying
- Stainless steel construction resists corrosion from harsh chemicals and fertilizers
- Diaphragm design provides positive shutoff without sticking or binding
- Standard threading fits most TeeJet boom systems without adapters
- Built to TeeJet specifications for consistent performance season after season
Built for Real Farm Work
These check valves are designed for sprayer booms on everything from small utility tractors to big self-propelled rigs. Whether you’re applying herbicides in corn, fungicides on soybeans, or liquid fertilizer on wheat, this valve keeps your application uniform by preventing those annoying drips that throw off your rates.
Made to Last
Chemical resistance is where stainless steel really shines. While other materials can get eaten up by aggressive chemicals, this valve keeps working year after year. The diaphragm design means fewer moving parts to wear out, and the whole assembly is built to handle the pressure cycling that comes with normal spraying operations.
Good to Know
Installation is straightforward—thread it into your boom body and you’re ready to go. The 10 PSI setting works well for most applications, giving you clean shutoff without requiring excessive pressure to start flow. If you’re replacing an existing check valve, it’s worth cleaning out the boom section while you’ve got it apart.
