The Inert (IPV) is a solenoid-operated diaphragm isolation valve for corrosive or high-purity fluids found in the medical-equipment, waterpurification, and clinical-chemistry industries. The IPV is suitable for closedloop operations. Its infinitely variable flow is proportional to the magnitude of incoming current. The poppet and seat in this 24-Vdcvalve driver give bubbletight sealing. The valve is rated to 60 psi and numerous porting and electrical connection options are available. Body materials include Ultem polyetherimide and Radel R polyphenylsulfone.
