Non-Return Valve
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. Our Parker Legris non-return valves are available in polymer, nickel-plated brass, stainless steel and POM. Push-in, threaded and adjustable versions available.
