Superalloy valves

Few engine components are subjected to stresses comparable to those to be withstood by valves, in particular exhaust valves; these are bathed by the gases issuing from the cylinder at a very high temperature, which can be as much as 910°C.
For these extreme applications, SCARPA & COLOMBO are able to offer the customer superalloy valves that can withstand a running temperature of up to 910°C. At the customer’s request we can provide the necessary assistance for the design of this type of valve.
