Before initiating the sampling process, the first critical step is the Sterilization-In-Place (SIP) procedure. During this stage, the Aseptic Sampling Valve is kept in a closed position to ensure all internal surfaces are properly sterilized.
To begin sampling, the valve is opened either by rotating the manual handle (for adjustable manual valves) or by activating the actuator (for automated versions). This action lifts the diaphragm and opens the shaft core, allowing sterile liquid to flow through the valve and into the sampling line.
After sampling is complete, the actuator is reversed to close the diaphragm valve. At this stage, the valve maintains a sterile connection between the two attached hoses, enabling another round of SIP sterilization to ensure full hygienic integrity of the system.
This aseptic sampling valve is designed for use in cleanroom environments and is ideal for applications in pharmaceutical, biotechnology, dairy, and beverage industries, where sanitary processing and contamination prevention are paramount.
