Description
If you’ve ever had chemicals dripping from your boom nozzles after you shut off the sprayer, you know how frustrating and wasteful that can be. This little brass check valve solves that problem by stopping flow when pressure drops below 7 PSI, so your spray pattern stays clean and you don’t lose expensive chemicals to the ground.
What You’re Getting
- Reliable 7 PSI activation keeps nozzles from dripping when you shut off
- Solid brass construction that stands up to farm chemicals and daily use
- Standard 1/4″ NPT connections that fit most boom setups
- Compact 1-7/16″ length won’t interfere with boom spacing or folding
- Diaphragm design provides smooth operation and long service life
Built for Real Farm Work
This check valve fits into spray boom systems where you need to prevent dripping and maintain consistent spray patterns. Whether you’re running herbicides, fungicides, or liquid fertilizer through your boom, this valve keeps things flowing when they should and stops them when they shouldn’t.
Made to Last
Brass holds up to farm chemicals and weather better than plastic alternatives. The threads stay sharp, the connections stay tight, and you won’t find yourself constantly replacing worn-out valves. TeeJet has been making quality spray components for decades, and this valve shows why farmers trust their products.
Installation Notes
Threads right into your boom between the supply line and nozzle body—most installations take just a few minutes with basic wrenches. Make sure to use thread sealant to prevent leaks, and check that your system pressure stays above 7 PSI during normal operation for proper valve function.
