Key Features of Alfa Laval SB Membrane Sample Valve
- Reliable Sampling & Hygiene
- The Alfa Laval SB Membrane Sample Valve provides high sampling reliability, ensuring consistent sample quality every time. Constructed from a single stainless steel piece without welds, it eliminates crevices or pores, significantly reducing bacterial contamination risks.
- Enhanced Cleanability and Hygiene
- The design of the valve enables effective sterilization through CIP and SIP processes, ensuring easy and thorough cleaning. Its hygienic silicone membrane sealing ensures representative sampling and prevents contamination risks between samples.
- Versatile and User-friendly Operation
- Available in multiple actuator configurations—manual, manual with micro port for hypodermic needle sampling, and pneumatic operation—the SB Membrane Valve suits varied operational requirements, making it versatile across industries.
Concept
The membrane sample valve is used for sampling from tanks and pipework under sterile conditions. The valve is sterilized in place with alcohol or steam. Membrane sealing directly against product ensures representative sampling, giving repeatable results safe to secondary contamination.
Working principle
Before opening the valve, the closing cap should be placed on upper hose piece. When handle is placed into horizontal position the required flow through the lower outlet is obtained. When handle is back into vertical position the valve is closed and the handle can be removed if required. Aseptic sampling is possible from a special valve type with micro port. By removing the red closing cap, a hypodermic needle can be inserted through a central channel into the membrane and the aseptic sampling takes place with the valve in closed position. After sampling the valve should be flushed with water or alcohol. Sterilization has to take place by means of alcohol or steam.
Standard Design
All types are available for manual or pneumatic operation. The two outlets are hose pieces designed as clip-on. The standard valve is equipped with one clip-on closing cap.
