Description

When you’re out spraying fields and the pressure starts building up beyond safe levels, you need something that’ll automatically dump the excess before it damages your pump or creates unsafe operating conditions. This 75 psi pressure relief valve does exactly that—it’s your sprayer system’s safety net that keeps things running smoothly and protects your investment.

What You’re Getting

Precise 75 psi opening pressure that protects pumps and system components from damage
1-inch manifold connection that handles high flow rates without restriction
Durable polypropylene construction that resists agricultural chemicals and weather
Spring-loaded design provides consistent pressure regulation season after season

Built for Real Farm Work

This valve is designed for sprayer manifolds on field sprayers, spot sprayers, and boom applicators where you need reliable pressure control. Whether you’re applying herbicides, insecticides, or liquid fertilizer, this valve keeps your system operating within safe parameters while you focus on getting the job done right.

Made to Last

Agricultural spraying is tough on equipment, with chemicals, temperature swings, and constant vibration. This relief valve uses chemical-resistant materials and a robust spring mechanism that won’t corrode or stick when you need it most. The manifold design handles the flow volumes typical of modern sprayer systems without creating back pressure.

Installation Notes

This mounts directly to your sprayer manifold using standard 1-inch NPT threads. Install it in the return line position so excess pressure gets dumped back to the tank rather than through your nozzles. A quick tip—check the valve operation at the start of each season by gradually increasing pressure to make sure it opens at the right setting.
