Inquiry (采购产品): Controller I am interested in switching out some systems to use controlled valves. I have one in mind from Cole-Parmer; a 12 VDC valve, which I want to be able to adjust the flow from 0 - 100% using a controller for consitant results. Thank you for the help; Tom. **** Hidden Message ***** Tom Blakley Milwaukee, WI 53233 USA Company: Aldrich Title: Superviser E-mail: tblakley@sial.com **** Hidden Message ***** tblakley@sial.com
