Description
When your sprayer starts building too much pressure, this relief valve is what keeps your system safe from damage. Nothing ruins a day of spraying like a blown hose or cracked pump housing, and that’s exactly what happens when pressure gets out of control. This 3/4-inch relief valve from Hypro acts like a safety guard, automatically releasing excess pressure before it can cause expensive problems.
What You’re Getting
- Reliable 150 PSI relief setting protects your pump and spray lines from dangerous over-pressure
- 3/4-inch inlet fits most common agricultural sprayer systems and pump setups
- Spring-loaded design responds instantly when pressure exceeds safe limits
- Built by Hypro, a trusted name in spray equipment components
Built for Real Farm Work
This valve fits right into most field sprayers, pull-type units, and truck-mounted spray systems where maintaining proper pressure is critical. Whether you’re applying herbicides across corn fields, running fungicides through soybeans, or spot-spraying pastures, the 150 PSI setting gives you the protection you need without interfering with normal spray operations.
Made to Last
Farm spraying puts equipment through tough conditions – chemical exposure, temperature swings, and constant pressure cycling. This relief valve handles it all with corrosion-resistant materials and a precision spring that maintains accurate pressure settings season after season, even when exposed to the harsh chemicals that go through spray systems.
Good to Know
Install this valve on the pressure side of your pump, usually right after the pump outlet. Make sure your system pressure normally runs well below 150 PSI so the valve only opens during actual over-pressure situations. If it’s constantly relieving during normal operation, you’ll need to check for restrictions in your spray lines or nozzles.
