ASEPCO tank valves

Our family of tank diaphragm valves are designed to minimise contamination risk, maintenance and lifetime cost.

The industry's leading tank valve

ASEPCO valves are designed to minimise risk. Changing a diaphragm takes seconds, with no special tools or training, and a simple Tri-Clamp assembly makes inspection fast and easy. Our valves are manufactured to comply with multiple global industry standards, safeguarding you and your process.

ASEPCO Weirless Radial diaphragm tank valve

Designed to save you time

  • Patented radial diaphragm, eliminates entrapment for
    easy cleaning
  • Simple, Tri-Clamp assembly makes maintenance 80% faster
  • Truly flush mount design, no gaskets, bolts or seams
  • Integrated travel stops
  • No readjustment or retightening
  • Up to three ports for CIP/SIP or flushing while closed

Strong and lightweight actuators

Our tank valve actuators are available in 2 series; the AJS actuator series for heavy-duty applications or the AKS actuator series for lighter weight needs.

Both series offer manual and pneumatic options, are laser-etched for traceability, and carry a market-leading three year warranty.



Long-lasting, quick-change diaphragms

The valve diaphragm can be changed in seconds, without special training or tools. Customers tell us this reduces maintenance time by as much as 80% compared to other valve technologies. Our patented, radial shoulder seal design gives consistent, leak-free, uniform sealing. 

Diaphragms are offered in eight different materials to cover every biotechnology and pharmaceutical application.
