You spoke… We listened! Our hydrodynamic design is based on your request for enhanced temperature control and sample system cleanability. We hired a rocket scientist to help design it, so you don’t have to be one to use it. ASEPCO’s valves don’t add complications; instead they are proven to simplify maintenance and reduce downtime. And, they keep on saving you money every year they are in use.
Valve sizes: 0.5″

Sample Valve with Callouts

  • Improved cleanability created by the angle of the fittings entering the valve body
  • Excellent drainability created by the “V” shape inside the valve chamber
  • Allows closer jacketing to tank because fittings are angled away from vessel at a quicker rate
  • Improved tank cleanability because the tip of the diaphragm seals on the ID of the vessel wall
  • Unique ASEPCO port that allows through the chamber CIP/SIP, ensuring a truly representative sample every time
  • Simple “Sample and Steam” valve body allows full steaming while valve is closed

Tank sampling drawing featuring the ASEPCO Radial-Diaphragm Sample Valve

You mean I can take a truly representative sample in an uncontrolled environment??

It’s simple with this 4-valve rig from ASEPCO, and it’s impossible to do so easily and reliably any other way.

Just follow these simple steps:

  1. Autoclave a bagged sample bottle with a filter and an ASEPCO valve (V3) sealing the opening.
  2. Unbag the sample bottle as shown, connecting the closed V3 to the closed tank sample Valve V2.
  3. Steam behind the flow paths of V2 and V3 as shown in pink.
  4. Close steam source (V1) and condensate drain (V4). You now have a sterile path between your process and your sample bottle.
  5. Open the sample bottle (V3) and the tank sample valve (V2), and take your sample as shown in blue.
  6. Close the sample valve (V2), then the sample receptacle valve (V3). Drain V4 (lose less than 15 ml of product with the ASEPCO close-coupled condensate valve) and remove your sample bottle.

CONGRATULATIONS! You have a sample that is truly representative of your process fluid. You can do this reliably at any time during the process, each time using the behind-the-seat flowpath design of ASEPCO valves to ensure the aseptic control of your sample.
