Zero dead leg valves

Overview

ASEPCO Weirless Radial diaphragm™ Zero dead leg valve

Designed specifically to meet the stringent requirements of the bioprocessing industry Weirless Radial diaphragm tank valves offer solutions to the most challenging applications. It is easy to weld our valves truly flush to the bottom of your tank with our heavy‑duty, thick weld flange. There are no gaskets, bolts or seams.

Features and benefits

  • For use in situations where sampling, draining, transferring or directing fluid from a line is necessary
  • Designed to minimise hold-up in point-of-use applications
  • Completely eliminates any dead legs
  • Drains completely, because unlike other designs, our valves have no pockets
  • Eliminates hold up, because the tip of the diaphragm seals on the ID of the line tubing
  • Flush mount design, simple clamp assembly
  • CIP/SIP capable for easy, repeatable cleaning and sterilisation
