Spartan Scientific: Series 4D85
The Spartan Scientific Series 4D85 is a direct operating 2-Way 2-Position media separated valve for control of aggressive media that can damage wetted solenoid valve components. The valve incorporates the innovative Spring Diaphragm which retains the media in the valve body effectively separating the metal operator components from the media for extremely long life cycles and media compatibility. The 4D85 is a stand alone body ported valve, available in 1/4", 3/8", and 1/2" NPT port connections and offers a full flow 12.5mm orifice. The 4D85 can control media compatible with Glass-Filled Nylon, PEI, and FKM, EPDM, and NBR elastomers. Available in all standard voltages, the 4D85 can control up to 20 PSI inlet pressure with no minimum operating pressure differential. The fully nylon encapsulated coils are available in DIN 43560 Form "A" and flying leads. The 4D85 valve body features robust design elements such as all stainless hardware and metal reinforced port rings which virtually eliminate valve body damage. The 4D85 is designed for a long trouble free life while still controlling compatible aggressive fluids.
