Sterile sampling valves with options for micro-biological sample analysis. MSV comes in a variety of options to suit various needs
The Alfa Laval SB Membrane Sample Valve provides a compact and cost-effective way to obtain bulk or aseptic samples of brewery, food, dairy and beverage products, including highly viscous products, such as harvest yeast.
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.
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.
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.
