Description

When you’re moving large volumes of liquid through your sprayer or tank system, you need a valve that keeps flow moving in the right direction and prevents backflow when the pump shuts off. This 3-inch polypropylene check valve does exactly that—it lets fluid flow forward under pressure but snaps shut the instant pressure drops, protecting your pump and keeping your system running clean.

What You’re Getting

One-piece polypropylene construction that won’t corrode from chemicals or fertilizers
150 PSI pressure rating handles heavy-duty agricultural applications
Low-pressure spring (1-2 PSI) opens easily but closes fast to prevent backflow
3-inch NPT threaded connections fit standard agricultural plumbing
EPDM gasket material resists chemical breakdown and maintains its seal

Built for Real Farm Work

This check valve is perfect for agricultural sprayers, tank systems, and irrigation setups where you’re moving water, liquid fertilizer, or chemicals through 3-inch lines. Whether you’re filling spray tanks, running irrigation pumps, or protecting centrifugal pumps from backflow damage, this valve handles the job without getting in the way of normal operation.

Made to Last

The glass-filled polypropylene body stands up to harsh agricultural chemicals and weather while staying lightweight for easy handling. The 316 stainless steel spring won’t rust or weaken over time, and the EPDM gasket maintains its flexibility even after thousands of pressure cycles.

Good to Know

Install this valve with the flow arrow pointing in the direction you want fluid to move—it only works one way. The low spring pressure means it won’t restrict flow during normal operation, but it closes instantly when pressure drops to protect your equipment from damage.
