C ~ Tined ( Gar letter to you of May 13, 1975, on the subject of nain stean isolation valves contained an error involving valve nomenclaturo. In the letter I and the enclosuru, the r:ference in n "Y-pattern globe valvo" should j have been "angic non-rnturn valvo." The valve failure which occurred fj during startup involved an angle non-return valve of the lif t-check type and not a Y-pattorn globo valvo. Please reviso your response

      -{                          accordingly.

Sincerely, Onginal signed by :
