Parker's check valves allow compressed air to flow in one direction and prevent it from flowing in the other. Fitted upstream of the circuit to be protected, they provide total protection. Using different color codes for supply and exhaust versions, these valves avoid any mistakes in the installation process. By making the installation safer and more intuitive, installation costs are reduced.
