The Alfa Laval SB Membrane Sampling Valve is a hygienic valve that enables representative sampling of products from tanks and pipework under sterile conditions. It provides the high accuracy, exceptional repeatability and excellent reliability required for high-quality, cost-effective sampling.
Benefits
• Hygienic and sterilizable to ensure hygienic sampling at low investment cost
• No sampling contamination risk due to effective Sterilization-in-Place before and after each sampling
• Flexible sampling methods: manual activation, manual with micro port for hypodermic needle, or pneumatic versions
• Safe, reliable sampling procedures
Standard design
The membrane sampling valve consists of a valve body, a membrane seal which works as a stretchable plug, and an actuator and/or handle to open and close the valve. To minimize the risk of contamination, the valve is sterilized in place using alcohol or steam. The membrane forms a seal directly against the product to ensure representative sampling and provide accurate, repeatable results without any risk of secondary contamination. The valve is available in three different actuator designs: • Manual - For manual activation • Manual + Micro Port - For manual activation or sampling using a hypodermic needle to penetrate the membrane for sample taking • Manual + Pneumatic - For manual or pneumatic activation when the valve is connected to pipes for automatic sampling Supplied with pipe outlet connections, the valve is available with three different types of connection: tank, pipe and threaded. All types are available for manual or pneumatic operation, or a combination of both. The two connections are hose pieces designed as clip-on. The standard valve is equipped with one clip-on closing cap.
Working principle
Before opening the Alfa Laval SB Membrane Sampling Valve, the closing cap should be placed on the upper hose to avoid any product leaving the upper port. When the handle is turned to the horizontal position, the sample starts to flow through the lower outlet. When the handle is turned back to the vertical position, the valve shuts and the handle can be removed, if required. Samples can be taken using a special valve type with a micro port; removal of the red cap enables the insertion of a hypodermic needle through a central channel and into the membrane to take a sample with the valve in the shut position. After sampling, flush the valve with water or alcohol. The valve can be sterilized using alcohol or steam.
