Description

When you’re running a sprayer, keeping your system pressure right where it needs to be can mean the difference between good coverage and wasted chemical. If your pressure gets too high, you’ll blow out seals or damage your pump—if it’s too low, you won’t get proper spray patterns. This diaphragm-type pressure relief valve keeps things in the sweet spot by automatically venting excess pressure when your system hits 300 PSI.

What You’re Getting

Reliable diaphragm design that responds quickly to pressure changes
Durable nylon body with aluminum bonnet that handles chemical exposure
300 PSI rating perfect for most field spraying applications
1/2 inch female NPT connection fits standard sprayer plumbing
Manual operation lets you adjust or test the system when needed

Built for Real Farm Work

This valve is designed for agricultural sprayers where you’re putting down herbicides, fungicides, or fertilizer. Whether you’re running a pull-behind boom sprayer, a three-point hitch unit, or a tank sprayer on your ATV, this valve protects your pump and keeps your pressure consistent across the boom.

Made to Last

The nylon and aluminum construction stands up to agricultural chemicals and field conditions season after season. The diaphragm design is more reliable than spring-loaded valves because there are fewer moving parts to wear out or get gummed up with chemical residue.

Good to Know

Installation is straightforward—just thread it into your pressure line after the pump but before your boom sections. Make sure to orient it so the relief port points away from anything that could be damaged by chemical spray. If you’re dealing with sticky pressure readings, this valve might be exactly what you need to get your sprayer running smoothly again.
