Control/PID Valve

Find something that is typically sold and serviced locally, but also has an international presence. GlobalSpec is a good place to search for suppliers.

Yes, he may find in Honeywell - they are into manufacturing smart valves with his typical application or perhaps from flowserve -I guess and assume such brands are on the list in Global Spec.

You need to start a dialogue with your local, friendly, Valves Distributor. You'll find them in your local Yellow Pages, among many other places, together with their phone number. They've got so many Valves available, they'll sell you one just to get rid of it.

With that snippet, I can't recommend anything at all, Mildred.

All you need is to call the valve suppliers and explain to them what is your requirement in your control and they will proposed you the suitable valve for your steam control. Since you are controlling the temperature by limiting the steam, then you need to look for the steam valve suppliers. These valves are different from the normal valve we use for water or for gas.
