Description
When your sprayer system starts building too much pressure, you need a reliable safety valve that’ll protect your equipment and keep chemicals flowing where they should. This TeeJet brass pressure relief valve automatically opens at 700 PSI to prevent dangerous pressure spikes that can damage pumps, hoses, and spray tips—problems that can shut down your operation right when you need it most.
What You’re Getting
- Solid brass construction that stands up to agricultural chemicals and constant use
- 700 PSI relief setting protects expensive spray system components from over-pressure damage
- 3/4″ female NPT threads fit standard sprayer plumbing and make installation straightforward
- Manual valve design gives you reliable, mechanical pressure control without electronics to fail
- Built by TeeJet, the name farmers trust for spray system components
Built for Real Farm Work
This valve is designed for agricultural sprayers, whether you’re running a pull-type rig behind your tractor for herbicide applications, operating a high-clearance self-propelled sprayer in corn and soybeans, or using a smaller three-point unit for pasture management. The 700 PSI rating handles the pressure requirements of most field spraying operations while providing that extra margin of safety.
Made to Last
Brass construction means this valve won’t corrode when exposed to common farm chemicals, fertilizers, and the weather conditions your sprayer sees season after season. The threads stay sharp, the internal components resist wear, and you won’t find yourself replacing it every couple of years like you might with cheaper alternatives.
Installation Notes
This valve threads right into your sprayer’s pressure line using standard 3/4″ NPT fittings—usually takes about ten minutes to install. Most folks mount it close to the pump discharge so it can protect the entire system. Make sure to use thread sealant on the NPT connections to prevent any weeping around the threads.
