I have 8 Spartan Scientific valves, does anyone know anything about these? Cost? How to rewire to a dual-port-bag setup?
first time i have heard of thoes they look like they are not made for the applaction you want just get some gc450 or 250
these were purchased in 2002 there are pictures of similar valves on the Spartan Scientific website. I'm starting to get the feeling i was ripped off...
