Check valves

Check valves prevent backflow. They are designed to keep fluids and gases moving in one direction.

This means they are ideal for industries where cross contamination is an issue, such as a plumbing system.

Our products are manufactured in brass, stainless steel, PVC, and cast iron.

We have check valves in: swing check, spring assisted check, and spring assisted y-check designs.

They come in NPT threaded or flanged connection styles.


Our sizes range from ¼” to 4”.
