solenoid valve
Just FYI, I bought a soleniod valve from Teco Pneumatic in Pleasanton,
CA (925-426-8500) for CO2 control. The engineer I spoke to (Larry)
suggested an Allenair 2CD8B-C-12DC. This is a 2-way, normally closed
valve with 1/8" NPT ports. This was a 12 VDC model but was available
in many other voltages too. Cost was about $35 and I picked it up the
same day. I mentioned the Humphrey 310 that had been mentioned in
other solenoid messages here. They had it for only $22. The
engineers suggestion to not go with the Humphrey was that the seal
material would be degraded by long term exposure to CO2. He said it
may not really be a concern at the pressures and flow rates used here,
though.
