How Do Sampling Valves Work?
Alfa Laval sampling valves enable operators to extract representative samples of process liquids for analysis, ensuring accurate quality control. These valves can be operated manually, pneumatically, or through a combination of both methods, providing flexibility for various process requirements.
For sterile sampling, a hypodermic needle is inserted into a rubber membrane plug, enabling contamination-free extraction of the process liquid for evaluation. This design ensures reliable, hygienic sampling for precise quality assessment in hygienic and aseptic processes.
