as per ASMe B31.1 ; cl:122.4 on attemperator block valave ''regulating valve shall be installed upstream of the stop valve. In additon, if the steam generator supplies steam to the steam turbine, a power operated block valves shall be installed upstream of the regulating valve."" - this is self explanatory as i am working on EN boiler and i am looking for the same or equavalent sentence inorder to install the manual operated or block valve.

ASME B31.1 / ASME TDP-1 desuperheater piping.

AFAIK, there's no EN equivalent of ASME TDP-1, or other standard which specifies the functional & operational design of piping & valves around boilers. But I may be wrong as I dont deal with them that often. National or local jurisiction may however dictate such requirements. Which country is it for?

Water carryover into a hot steam turbine can result in catastrophic damage to the turbine. Sound engineering judgment would dictate installing a power operated block valve. A manual valve is not sufficient since a turbine (plant) operator cannot act fast enough to prevent damage to the turbine.
Best of luck!
