VDMX DMAX diaphragm valve are used in a wide variety of process and ancillary fluid applications, designed for efficient cleaning. The aseptic bearing shut-off valve is fitted with a fluid (cleaning/rinsing) or vapor circulation bearing.The DMX DMAX diaphragm valve allows for retention free flow and a constant flow diameter. Its design, integrating a physical barrier between the interior of the valve and the external environment, makes for a valve particularly adapted to the pharmaceutical industry.
