Le valve was cycled six times success-On the seventh test cycle the pilot valve did not close.- De ERV-. fully. was isolated and per sitted to cool down while vaiting for Crosby represents-tives. [ Crosby rep., k' alt Conroy, arri ed and the pilot valve asse=bly vas re=oved from the main valve. Disasse=bly of the 111ot vsive revealed thnt the pilct valve sten had stuck open due to the cler< tole-ance causing a binding con-dition between the O.D. of the stem and the I. J. of the pilot valve nozzle. l Also, a small metal particle was found in the pilot ste=/noz:1? area. Sd-sequent cleasing of the inlet piping to the ERY revealed this same type of metal particles. he Crosby representative furnishil a detailed drawin_. of the pilot valve stem requiring a diaceter of.37h_ nis was chacged to read.30 diaseter r. _.s-m ~.373 * .372 by the Crosby rep., and the stem was modified accordingly by TECo l'.aintenssee under the directics of the Crosby rep. Bis =odification resulted in opening the clears =ce between the stes and the no::le thus eliminating the binding. De nozzle was also ree=ed out vitb. a reamer the sac: size, no material was removed. All parts vere cleaned and assembled. De solenoid linkage vas adjusted to drop the adjustment bolt r. ore squarely on the disc aciiuator. In addition, the adjustnent belt was positio'ned to =ove the pilot valve stem off the seat a m W of.125". It had been moving off the seat sc=e.375". De pilot va.lve was tested without pressure by actuating the solenoid three Le valve was tested again twice with 5 or 6 seconds between tests. times.
