Unique Sampling Valve
Alfa Laval Unique Sampling Valve
The Alfa Laval Unique Sampling Valve (Double Seat) is designed for hygienic processes, allowing for representative sampling under sterile conditions. It offers high accuracy, exceptional repeatability, and outstanding reliability, making it ideal for cost-effective sampling. Users can achieve precise control during sampling with either the ergonomically designed handle or the actuator. The entire seat can be sterilised between sampling sessions, significantly reducing the risk of cross-contamination.
This Double-Seat Sampling Valve is specifically tailored a variety of hygienic processes including food and beverage, personal care and pharmaceutical.
SB Pressure Relief Valve Benefits

- Highly reliable operation and 3-year warranty for non-wearing parts
- Multiple features for safe sampling
- Enhanced cleanability
Temperature
Temperature range: 1°C – 130°C
Max. sterilisation temperature, dry steam (2 bar): 121°C
NB: Steam must be dry, since condensate will damage the membrane seal. It is recommended that the membrane seal is changed every 500 samples/sterilisations or in accordance with condition.
Pressure
Max. working pressure: 600 kPa (6 bar)
Min. working pressure: 0 kPa (0 bar)
ATEX
Classification size 4 & 10 Manually: II 2 G D
Materials
Valve body: 1.4404 (316L) with 3.1 cert.
Actuator: 1.4301 (304), 1.4404 (316L)
Membrane seal: EPDM, silicone

How the Unique Sampling Valve Works
Single Seat:
The Single Seat Unique Sampling Valve is designed for standard hygienic sampling.
The Single Seat Sampling Valve has two positions: open and shut.
Open position:
Manual Valve: rotate the handle in a counterclockwise direction to open the Valve.
Pneumatic Valve: open the Valve by activating the actuator.
This retracts the Valve stem and the membrane, which enables the product to flow freely through the open Valve.
Shut position:
Manual Valve: rotate the handle in a clockwise direction to close the Valve.
Pneumatic Valve: shut the air supply to stop the flow of product from the Valve.
In the closed position, the Valve body is now ready for sterilisation.
Double Seat:
The Double Seat Unique Sampling Valve is designed for truly sterile sampling and ensures higher cleanability.
The Double Seat Sampling Valve has three positions: open, shut and sterilisation.
Open position:
Manual Valve: rotate the handle in a counterclockwise direction to open the valve.
Pneumatic Valve: open the valve by activating the actuator.
This retracts the Valve stem and membrane seal, which enables the product to flow freely through the open Valve.
Shut position:
Manual Valve: rotate the handle in a clockwise direction to close the Valve.
Pneumatic Valve: shut the air supply to stop the flow of product from the Valve.
In the closed position, the Valve body is now ready for sterilisation.
Sterilisation position:
Manual Valve: rotate the handle clockwise to the steam position.
Pneumatic Valve: apply air to the steam connection.
This extends the inner spindle of the Valve head into the inner seat and stops product flow in the Valve port. At the same time, the outer spindle of the Valve 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 sterilisation.
