Description

When you’re spraying crops and need to turn off a section or shut down the whole boom, you don’t want chemicals dripping from the nozzles after the pressure drops. That’s where a diaphragm check valve earns its keep—it stops the backflow and drip that can waste expensive chemicals and create uneven application. This TeeJet valve keeps your spray system running clean and efficient.

What You’re Getting

10 PSI opening pressure that prevents dripping when boom sections shut off
Nylon construction that resists farm chemicals and UV damage
1/8 Male NPT thread with 11/16 cap thread for secure boom mounting
Compact design that won’t interfere with boom folding or transport

Built for Real Farm Work

This check valve works in any TeeJet sprayer boom system where you need to control chemical flow and prevent drip-back. Whether you’re running a pull-type sprayer through corn or using a self-propelled unit on soybeans, this valve keeps the chemicals flowing forward when you want them to and stops them cold when you don’t.

Made to Last

The nylon body stands up to the harsh chemicals you’re spraying day after day while staying lightweight for boom applications. The diaphragm design gives you reliable shutoff without the stick-and-slip problems you get with ball valves in chemical applications.

Good to Know

Installation is straightforward—just thread it into your boom plumbing where you need flow control. The 10 PSI setting works well with most agricultural spray systems. If you’re having drip problems at the nozzles when sections shut off, adding these check valves upstream usually solves the issue.
