Does any know if there is any guide for valve packing selection based on service and temperature?The guides I know of are all based on either elastomer suppliers of products (sealings in general, O-rings) wich will be able to guide you regarding temperature, chemical resistence and pressure for known mechanical products (eg. o-rings etc)or:from larger suppliers of a wide range of for instance BFL centric valves. Bray, Tyco Controls and many others.I think this would be the way to go.As a curiosium: the German solenoid valve company Herion, now owned by Norgren, published in 1985 (In German only!) a very good handbook on different, common chemicals, chemical properties and crossrelated to different materials for body and sealings, again crossrelated to a limitid range of common temperatures and pressures, all materiales ranged as plus or minus.Although limitid, and issued primarily for solenoid valves, this is still in my posession in a reachable shelf from my office chair.I also would be grateful if somebody could point to something like this available today.
