Description

Nothing’s worse than watching chemical drip from your nozzles after you’ve shut off the boom. That mess costs you money and can burn your crops if you’re not careful. This TeeJet diaphragm check valve stops that backflow right at the source, keeping your spray where it belongs and your application rates exactly where you set them.

What You’re Getting

10 PSI cracking pressure ensures valves stay closed until you need them to spray
Nylon construction resists corrosion from harsh chemicals and fertilizers
Diaphragm design provides reliable sealing without sticking or binding
1/4 inch Male NPT inlet with 11/16 MBNT cap thread outlet for easy boom integration
Direct replacement for OEM parts – no modifications needed

Built for Real Farm Work

This check valve’s designed specifically for sprayer boom systems where consistent flow control matters. Whether you’re running post-emerge herbicide on corn, fungicide on soybeans, or liquid fertilizer on wheat, this valve ensures each nozzle gets the right amount of product when you turn on the boom and stops flowing cleanly when you shut it off.

Made to Last

Farm chemicals are tough on equipment, but this nylon body handles the acids and bases you’ll run through it season after season. The diaphragm design means fewer moving parts to wear out, and TeeJet’s been making these valves for decades – they know what works in the field.

Installation Notes

These typically install right at the nozzle body or in the boom plumbing near each spray tip. Use pipe dope or Teflon tape on the NPT threads, and don’t over-tighten – the nylon threads are strong but you can strip them if you get too aggressive with the wrench.
