different material properties are created in area’s where needed.The high tech Ti3Al
alloy has also very good material properties at high temperatures.The special coating
creates considerably lower friction between the valve and other parts like valve guides.
Therefore the PROX valves exceed OE specifications in dimensions and reliability.
