Description
You know how annoying it is when your sprayer boom keeps dripping after you shut off the main valve—chemical pooling under nozzles, wasted product, and uneven coverage the next time you start up. This TeeJet diaphragm check valve puts a stop to all that by automatically shutting off flow when pressure drops, keeping your boom lines tight and your chemicals where they belong.
What You’re Getting
- 7 PSI activation setting prevents unwanted drip and flow when sprayer is shut down
- Solid brass construction stands up to harsh chemicals and field conditions
- Diaphragm design provides reliable, repeatable shut-off without sticking
- 1/8″ female NPT inlet with 11/16″ male cap thread outlet fits most boom setups
- Direct replacement for TeeJet systems—no modifications needed
Built for Real Farm Work
This check valve is designed for sprayer boom applications where you need consistent flow control. Whether you’re running herbicide, fungicide, or insecticide through field sprayers, pull-type booms, or three-point spray rigs, this valve keeps your system operating like it should.
Made to Last
The brass body resists corrosion from agricultural chemicals while the diaphragm design eliminates the wear points you get with ball-type check valves. This means reliable operation season after season, even with the harsh chemicals that can eat up lesser components.
Installation Notes
Thread this valve into your boom line between the main supply and your nozzle bodies. Make sure to install it with the flow arrow pointing toward the nozzles. A little pipe dope on the threads ensures a leak-free connection that’ll hold up to your system’s operating pressure.
