Pneumatic Check Valves

Motion offers pneumatic check valves that are filtered by cracking pressure, body material, and port size. Pneumatic check valves allow pneumatic energy to flow in one direction only. They have two openings, or ports: an intake valve, which allows air to enter, and an output valve through which air flows out. Check valves work automatically and are not powered by external control. They are excellent for protecting systems from backflow and will not re-intake substances and contaminate the source.
