Coverley - Production Engineer} [Struck through] E {Mr Elliott - Chief Engineer} /JNR. {Charles L. Jenner} 2/HP.23.1.36. Phantom III - Radiator Steam Valve. We send you herewith:- LeC.4931 which is No.3. design for the above. This consists of a thermoflex bellows for the carrying of the valve. The size chosen conveniently drops into the existing pot and there is no alteration to the top screwed cap. A new standpipe is necessary because we want a conical valve seat. The rating of the bellows should give approximately the desired blow-off pressure. LeC.4931 herewith. E {Mr Elliott - Chief Engineer} /JNR. {Charles L. Jenner} | ||
