Maybe should have posted this question in the Valve Engineering section, but then you would have received about 1,000 suggested suppliers. For this, don't bother. For Cryogenic gates and globes, stick with well known, long time suppliers of these products. Velan, Kitz, Samson (globes only), Emerson (globes only), Flowserve (both gate and globes). They know what they are doing and you won't get fired by specifying their products. All have been around for a long time, so their stuff works. Note that Samson and Emerson specialize in control type valves. Check the web-sites for more details on the products to best match your needs.
