Description

When you’re spraying crops and need to shut off sections of your boom or stop at headlands, you don’t want chemical dripping from your nozzles after the pressure drops. A diaphragm check valve stops the flow instantly when pressure drops, so you get clean starts and stops without wasting expensive inputs or creating streaks in your field. This TeeJet check valve keeps your applications precise and your chemical where it belongs.

What You’re Getting

Instant shutoff when pressure drops to prevent drip-back
Diaphragm design that handles thousands of pressure cycles without getting sticky
Stainless steel construction that resists corrosion from harsh chemicals
Standard pipe fittings for easy installation in your boom plumbing

Built for Real Farm Work

This check valve is perfect for boom sprayers, spot sprayers, and other agricultural spray equipment where you need to control drip-back when applying herbicide, fungicide, or liquid fertilizer. It fits into sprayer boom systems on everything from 3-point mounted units to self-propelled machines and keeps your application clean between passes or when turning at headlands.

Made to Last

The stainless steel construction won’t corrode or pit when exposed to the variety of chemicals you’ll be running through your sprayer. The diaphragm stays flexible and maintains its seal even when dealing with temperature changes and the vibration that comes with field work. This valve is built to handle season after season of demanding agricultural applications.

Installation Notes

Installation is straightforward—just thread it into your spray line using standard pipe thread compound or tape. Make sure to orient the flow direction correctly—there’s usually an arrow on the body. If you’re having issues with boom drip, check that your system pressure is adequate to keep the valve open during spraying.
