I thought you folks at the Engineering Physics Lab built custom instruments for your manufacturing divisions much as I do here in the Process Instrumentation Research Laboratory at ECC. We use solenoid valves all of the time in our ih-house designs, also sampling valves. In any event, the following list of manufacturers comes from the ISA (Instrument Society of America) Handbook of Instrumentation. You can probably find similar lists in the Thomas Register (look in any library) which you will have to consult anyway for addresses for these companies. Of those on the list, I have used ASCO, Skinner, and Numatics extensively. You mentioned DC valves, but I suspect you want something that can be switched with TTL or your computer. The currents involved with most low voltage DC valves are large and the inductive kick on turnoff requires some special care with DC coils. I would suggest using conventional 120VAC solenoid valves controlled by solid-state relays. Here is the list. By the way, give my regards to Joe Andrisani. PS: I am posting the list rather than mailing it because the question comes up frequently! Good luck, Barry ornitz@kodak.kodak.com ----------------- | ___ ________ | Dr. Barry L.
