SB Membrane Sample Valve

The Alfa Laval SB Membrane Sampling Valve is a compact, cost-effective way to take bulk or aseptic samples from tanks and pipework in breweries (and other hygienic processes such as food and dairy) under sterile conditions. This aseptic sampling valve is suitable for highly viscous products, such as harvest yeast, and ensures minimal risk of contamination, high accuracy, exceptional repeatability and excellent reliability.

Alva Laval SB Membrane Sampling Valve

Safe and secure in-line sampling in compact format

  • Aseptic and sterilizable to ensure hygienic sample at low investment cost
  • No sample contamination risk: designed for effective sterilization in place with alcohol or steam before and after each sample
  • Flexible sampling methods: available in manual activation, manual with microport for hypodermic needle or pneumatic versions
  • Reliable – rated to 10 bar pressure
  • Safe sampling procedures
Versatile hygienic design: Made of a single piece of stainless steel, the valve body features smooth, crevice-free surfaces. With no welding, there is no the risk of pore formation and cracking in the welds and subsequent risk of bacterial build-up. This highly versatile hygienic valve is available in several different versions to ensure sample reliability and safety for a broad range of applications.

Technology

The valve consists of a valve body, actuator and membrane seal placed on the stem of the actuator, which works as a stretchable plug. The valve is sterilized in place with alcohol or steam. The membrane forms a seal directly against the product to ensure representative sampling, and give repeatable results safe from 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. The valve is then supplied with pipe outlet connections.

Type T for Tank connection

The valve is available in three different mounting designs:

工作原理

Operating principle

The valve is available with three different types of connection: tank, pipe and threaded. They operate on the same principle. Before the valve is opened, the closure should be placed on the upper hose connection. 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. Aseptic sampling can be taken using a special valve type with microport. If you remove the red cap, you can insert a hypodermic needle through a central channel into the membrane to take an aseptic sampling 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.

As an option, Alfa Laval offers the Alfa Laval Steam Generator, which enables you to steam-sterilize where there is no permanent steam supply on hand.
