Abstract (en)
[origin: EP2743468A1] The valve has a valve body including a valve shaft (2) extending along axial valve shaft axles (A). A valve disk (3) is connected to the valve shaft and moved in an axial direction away from the valve shaft. A base surface (31) is formed between the valve disk and valve shaft orthogonally to the valve shaft axles, and a valve seat surface (32) is formed at the valve disk. A recess (4) in the form of a coating trough (41) is formed in the base surface. An anti-corrosive coating (5) in the form of a corrosion protection layer (51) is provided on the recess. An independent claim is also included for a method for manufacturing a gas shuttle valve.
