OverviewNordson EFD's 754V aseptic diaphragm dispense valve features a smooth, entrainment‑free fluid path and FDA‑compliant wetted parts suitable for CIP and SIP medical assembly processes. The electro‑polished fluid body increases corrosion resistance and durability. Flow range covers precise deposits from 0.5 µL up to continuous flow of 14.0 mL/s. The valve closes cleanly at each cycle with a fast cutoff that eliminates drips; internal threads are removed to simplify cleaning.
