Valves - tank valves

Point-of-use valves

Overview

ASEPCO Weirless Radial diaphragm™ Point-of-use 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

  • Designed to promote drainage, eliminate dead-legs and process steam stagnation
  • Provide a port to allow steam or material to be purged rather than trapped
  • U-shaped valve design draining or sampling
  • Integrated elbows for connection to piping loops
  • Minimal L/D ratio enables easy cleaning
  • Flush-mounted to the tank, no dead legs or dead spaces
  • Easy to clean and self-draining by design - can be CIP/SIP to eliminate caking
  • Available valve sizes: 0.5″, 0.75″, 1.0″, 1.5″, and 2.0″

Actuators

Actuators

The AKS actuator series** for tank valves is a durable, easy to maintain actuator made of a plastic housing and stainless steel diaphragm interface. The resulting actuator is a hygienic design which is GMP-compliant.

Our tank valve actuators are also available in the AJS actuator series an all stainless steel actuator providing all the same performance, but in a heavy-duty package.

Both versions offer manual and pneumatic options, are provided with laser-etched serial numbers for traceability, and carry a market-leading three year warranty. It is straightforward to add automation to the pneumatic versions by mounting switches or controllers from any manufacturer.

Work with all manufacturers linear switches and controllers (i.e. Westlock, Stonel, Burkert, etc.)

**AKS actuator series only available on 0.5-1.5" sizes

Diaphragms

Diaphragms

Multiple materials cope with virtually every temperature, pressure and chemical challenge in the food and biopharm industries.

Materials include:

  • Silicone
  • EPDM
  • Silicone plus
  • EPDM plus
  • Viton A
  • Viton A (steam resistant)
  • Viton GF
  • PTFE

All diaphragms are laser-etched with cure dates and batch numbers, ensuring that they are completely traceable.
