4DKR Series media-separated 2-way manifold valves

The 4DKR series by Spartan Scientific includes direct-acting 2-way, 2-position media-separated valves, designed for the control of aggressive media that can damage wetted solenoid valve components. This unique design incorporates an innovative spring diaphragm that 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.

Advantages

Innovative spring diaphragm for media separation and long life cycles.
Designed for manifold mounting for compact installations.
Suitable for aggressive media compatible with glass-filled nylon, PEI, FKM, EPDM, and NBR.
No minimum operating pressure differential required.
Robust design with stainless steel hardware.
Dust-tight and water-resistant (IP65/NEMA 4).
