with several integrated material micro structures, specific and 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.
