The Fittings | Vacuum Needle Valve (ø30) is a fine-metering vacuum needle valve for precise vacuum control on short-path and wiped-film distillation systems. The needle design allows incremental adjustment of vacuum bleed rate, enabling fine-tuning of system vacuum depth during distillation without abrupt pressure changes. Compatible with ø30 mm port connections on VTA vacuum manifolds and associated vacuum lines. An essential control component for achieving consistent vacuum depth and separation efficiency.
