Description

When you’re running a sprayer setup and need to keep system pressure in check, this TeeJet brass pressure relief valve does the job right. If your pump builds too much pressure—whether from throttling up too fast or nozzles getting plugged—this valve automatically opens to dump excess pressure back to the tank. That keeps your lines, fittings, and pump from taking a beating while protecting your spray pattern consistency.

What You’re Getting

Heavy-duty brass construction that handles agricultural chemicals without corroding
1-inch female NPT threads fit standard sprayer plumbing and tank returns
150 PSI maximum rating covers most boom sprayer and spot-spraying applications
Adjustable spring mechanism lets you set the exact relief pressure for your system
Manual design means no electrical connections—just install and it works

Built for Real Farm Work

This valve handles the tough conditions you’ll find on farm sprayers, from backpack units to pull-behind boom sprayers. Whether you’re spraying herbicide on row crops, applying liquid fertilizer, or spot-treating pastures, the 1-inch connection size moves enough volume to handle most agricultural pumps without creating a bottleneck.

Made to Last

Brass construction means this valve won’t pit or corrode when exposed to common agricultural chemicals like glyphosate, 2,4-D, or liquid nitrogen. The spring-loaded mechanism is built to cycle thousands of times without losing its calibration, and the NPT threads seal tight with standard pipe thread compound.

Installation Notes

Mount this valve in your return line between the pump and tank, with the outlet pointing back to the tank. Use pipe thread sealant on the NPT threads for a leak-free connection. The adjustment screw on top lets you dial in the relief pressure—start low and work up until your system holds the pressure you need without constantly cycling.
