| -2- Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}9/KW.6.9.35. (3) Are the KE-965 valves with stellited seats showing up well in bores 2 & 5 ? We see from the specification that the stellited valves are KE-965 and not silichrome. We will send out to you two stellited silichrome valves for bores 1 & 4, as these are the ones we really ought to try. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
