Non-return 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.
Non-return valves allow compressed air to flow in one direction and prevent it from flowing in the other. Mounted upstream of the circuit, they provide total protection. With different color codes for supply (green) and exhaust (red) version, you’ll be sure to not make a mistake. By making your installation safer and more intuitive, your installation cost is reduced.
