Air-Operated Fail Close & Fail Open Plastic Ball Valves
Fail-safe ball valves remain open or closed when there is a loss of power. A fail closed (FC) valve will close and a fail open (FO) valve will open. These plastic valves won't rust and are less prone to buildup, so they maintain better flow over time compared to metal valves. Connect them to a compressed air source to rotate the ball to start or stop flow.
