Answer Posted / Manojeet Goldar
Air to Close (ATC) valves are used more often than Air to Open (ATO) valves due to their design and functionality. ATC valves provide positive shutoff, meaning they seal tightly when closed, which is crucial in applications where a leak could cause problems. ATO valves, on the other hand, require a spring to return them to the closed position, making them less reliable in high-pressure or dirty air environments.
