Operating principles
Unique single-seat sampling valves
Designed for standard hygienic sampling, the single-seat sampling
valve has two positions: open and closed. It can easily be upgraded to a
double-seat valve by replacing the handle or actuator with an upgrade
kit.
Open position for sampling: To begin the sampling process, rotate the
handle in a counter-clockwise direction to open the valve, if using an
manual valve. If using a actuator, open the valve by activating the actuator. This retracts the valve stem and the membrane and enables the product to flow freely through the open valve.
Closed position for sterilization: To stop the sampling process, rotate
the handle in a clockwise direction to close the valve, if using a manual
valve or shut the air connection, if using a pneumatic actuator.
This shuts off the flow and makes the channel in between the connecting hoses available for sterilization. If steam is used for Sterilization-in-Place, Alfa Laval recommends the use of an optional pressure relief valve on the outlet.
A new level of accuracy with patented new technology
The design of single-seat technology poses challenges for complete
sterilization. In closed position, the membrane seal comes into contact
with the valve seat. These points of contact are virtually impossible to
clean due to tight surface compression and may therefore accumulate
product residue and microorganisms. For that extra level of security to
ensure a more representative sample, Alfa Laval recommends double seat technology.
Unique double-seat sampling valves
Designed for truly sterile sampling, the double-seat sampling valve has three positions: open, closed and sterilization.
Open position:
To begin the sampling process,
Manual valve: rotate the handle in a counter-clockwise direction to open the valve.
Pneumatic valve: supply air to the open connection.
This retracts the valve stem and membrane seal and enables the product to flow freely through the open valve.
Closed position:
To stop the sampling process:
Manual valve: Rotate the handle in a clockwise direction.
Pneumatic valve: Shut off the supplied air to the open connection.
Sterilization position:
To set the valve in sterilization position,
Manual valve: rotate the handle clockwise to the steam position.
Pneumatic valve: apply air to the steam connection.
This extends the valve heads inner spindle into the inner seat and stop product flow in the valve port. At the same time the valve heads outer spindle retracts and lifts the membrane seal away from its normal seat. Now it is possible to access the hard-to-reach areas on the seat surface, ensuring thorough sterilization and making the Unique double-seat sampling valve a solid and reliable choice to achieve 100% representative sampling.

High sampling reliability
The valve meets the requirements for high-quality product extraction in various hygienic processes with minimal risk of contamination. High accuracy, exceptional repeatability and excellent reliability are hallmarks of the valve.
Versatile hygienic design
Made of a single piece of stainless steel, valve body features smooth, crevice-free surfaces. Because no welding is required, the risk of pore formation and cracking in the welds and subsequent risk of bacterial build-up is eliminated. This highly versatile hygienic valve is available in several different designs to ensure sample reliability and safety for a broad range of applications.
Enhanced valve cleanability
Designed to help ensure effective sterilization before and after each sample, these valves are sterilized in place with alcohol or steam. This helps ensure a truly representative sample every time.
Product Benefits
- Low upfront investment costs
- Superior hygiene
- Compact size
Construction
The valve consists of a valve body, actuator and membrane seal, which is placed on the stem of the actuator and works as a stretchable plug. 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.
Operating principle
To take a sample, rotate the handle in a clockwise direction to open the valve. This retracts the membrane allowing the liquid to pass through the valve into the sample container. To close the valve for sterilization before and after taking each sample, rotate the handle in a counter-clockwise direction to channel between the valve ports is open for sterilization.
Function and cleaning
1 Alcohol sealed valve
2 Alcohol is drained and the valve can be steam sterilized
3 Sample is taken
4 Valve is flushed with water/alcohol
5 Valve is sealed with alcohol
Type W – Harvest Yeast Sample Valve
The valve is available in three different mounting designs:
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.

Scandi Brew (SB) Micro Sample Port
Widely used within the brewery, food, dairy and beverage industries, the Alfa Laval Scandi Brew Micro Sample Port enables representative aseptic and microbiological samples to be taken in small volumes from tanks and pipework.
Related Industries:
Food Processing, Beverage Processing
Aseptic sampling for microbiological control
To help ensure food and beverage safety, the sample port features a straightforward hygienic design with minimal components makes collecting samples mid-stream easy, convenient and accurate.
Versatile mounting
Direct mounting on the tank wall, pipe wall, or extruded pipe ends in either a vertical and horizontal position makes the port versatile and suitable for a broad range of applications and provides the flexibility needed to meet your sampling requirements.
Easy to clean
Hygienic design ensures optimum hygiene for representative sampling. When the port is located on the tank wall or pipe wall, the plug end that is flush with the wall is automatically cleaned during the routine Cleaning-in-Place (CIP) cycle. To minimize the risk of contamination, it is easy to sterilize the rest of the plug with alcohol before sampling.
Construction
The sample port consists of a housing made as a socket for direct welding into the tank wall or pipework, a rubber plug which is positioned by a press screw, an o-ring, chain and a closing cap. These different types of sockets are mounted:
- Socket, Type T, is welded into a 25-mm diameter hole in a tank wall
- Socket, Type P, is welded onto a pipe wall and, thereafter, an 8-mm hole is drilled
- Socket, Type PC, is available for welding onto extruded pipe ends equal to 1” as well as DN25
Operating principle
To take a sample, simply unscrew the closing cap and insert a one-mm hypodermic needle through the rubber plug.
