Spartan Scientific: Series 4DKR
The Spartan Scientific 4DKR is a direct operating 2-way 2-position media separated valve for control of aggressive media that can damage wetted solenoid valve components. This unique valve design 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 4DKR is a sub-based valve designed to be mounted on a manifold machined to match the design template for mounting screws and flow paths. The design is made so that the manifold can be easily machined using common tools so that common passageways can be machined in a block with one inlet and many outlets reducing the size needed for an installation as well as leak points and fittings with corresponding labor. The valve offers a full flow 12.5mm orifice and can control media compatible with Glass-Filled Nylon, PEI, FKM, EPDM, and NBR elastomers. Available in all standard voltages, the 4DKR can control up to 20 PSI inlet pressure with no minimum operating pressure differential. The fully nylon encapsulated coils are available as DIN 43560 Form A or flying leads. The 4DKR valve body features robust design elements such as all stainless hardware and is designed for a long trouble free life while still controlling compatible aggressive fluids.
