Hygienic Sampling Valves and Aseptic Sampling Valves provide a controlled way to collect representative samples from tanks and process pipelines while reducing contamination risk. Depending on the required hygiene level, the sampling path may be cleaned by CIP, sterilized by steam or SIP, and operated manually or pneumatically.
A sampling valve creates a controlled connection between the process and a sample container. Its design must protect the product, the sample and the operator while minimizing dead areas and supporting an appropriate cleaning or sterilization routine.
The correct design depends on the product, sample volume, sterilization method, installation point and required level of microbiological protection.
A membrane isolates the product zone from the operating mechanism. The sampling chamber can be steam sterilized before and after sampling for demanding aseptic duties.
A cost-effective cleanable solution for routine product sampling where CIP capability is required but full steam sterilization is not part of the operating procedure.
Designed for small-volume or microbiological samples, often using a septum or membrane accessed by a sterile hypodermic needle.
Welded directly into a vessel wall to obtain samples from the product volume while maintaining hygienic integration and an appropriate drainable orientation.
Installed on process pipework to collect samples from a flowing product. Correct location and orientation are essential for representative sampling.
Pneumatic operation supports automated sampling sequences, remote actuation and repeatable opening times in integrated process-control systems.
The exact procedure must follow the valve manufacturer's instructions and the plant's validated hygiene protocol. A typical steam-sterilizable sequence is shown below.
Confirm the sample container, valve condition and safe operating conditions.
Steam or sterilize the sampling chamber and outlet according to the procedure.
Open the valve and collect the required representative sample volume.
Close the sampling path and secure the sample for laboratory handling.
Clean or sterilize the outlet again and restore the valve to standby condition.
The Tetra Pak plant-components portfolio includes Keofitt sampling solutions. The W9 and Basix families form an important part of the OEM identification and part-number coverage developed for this LGN technical page.
The W9 is a steam-sterilizable aseptic sampling valve built around three principal elements: valve body, valve head and membrane. The membrane is positioned on the valve-head stem and functions as a stretchable sealing plug. Interchangeable bodies and heads make it possible to configure the valve for different installation and operating requirements.
Basix is a cost-efficient hygienic member of the W-series sampling-valve range. It is suitable for CIP cleaning but is not intended for steam sterilization.
Intended for products with viscosity up to 100 cP and particle sizes below 1.5 mm, with tank-weld, pipe-weld and clamp connection options.
The following page sections will separate Tetra Pak/Keofitt OEM references, Alfa Laval spare-part references and accessories to prevent incorrect cross-referencing.
This section converts the Tetra Pak plant-components information into a clear engineering and OEM identification guide. Valve bodies, operating heads, microports and complete Basix configurations are kept separate to prevent incorrect part-number selection.
Select by complete configuration—not by appearance alone. Confirm valve family, body connection, head type, membrane material and microport requirement before issuing an RFQ or ordering a replacement.
The W9 consists of a valve body, valve head and stretchable membrane. Valve bodies and heads are interchangeable, enabling different tank, pipeline and operating configurations. Microport versions permit small-volume sampling through a septum using a hypodermic needle.

Accessory part numbers depend on valve size, connection function and hose or tube diameter.
This OEM reference section covers the Alfa Laval Sampling Valve Type 20, the manual SB Membrane Sampling Valve, and the manual SB version equipped with a micro sampling port. Part numbers are organized by valve family and component to support accurate maintenance, identification and procurement.
The Type 20 is a compact legacy sampling valve manufactured in AISI 304. Its spare-parts list is simple, but correct identification remains important because the spindle, NBR O-ring and fibre packing are model-specific.
The assembly consists of a spindle, valve body, elastomeric O-ring and fibre packing. The valve body itself has no separate spare-part number in the referenced OEM table.
The catalog identifies the Type 20 assembly as AISI 304, with an NBR O-ring used as the principal elastomeric sealing component.
Alfa Laval marks the O-ring and fibre packing as the recommended spare parts for routine service of this valve.

The manual SB Membrane Sampling Valve uses a spring-loaded manual plunger and a replaceable membrane to isolate the process from the operating mechanism. Several membrane compounds and color-coded bushings are available.
The replaceable membrane forms the hygienic barrier between the process side and the spring/plunger mechanism.
The MSV spring and spring bushing support reliable manual closing after the operator releases the plunger.
The listed EPDM and Silicone membranes are supplied as packs of 20 pieces. Bushing color and membrane compound must be confirmed before ordering.

Correct sampling-valve selection is not based on brand name alone. The valve must match the required sample quality, sterilization method, process pressure, product characteristics, operator routine and available automation. This guide helps engineers and purchasing teams define the correct configuration before requesting a quotation.
Start with the required sample integrity and cleaning method. Then confirm actuation, installation point, elastomer compatibility and maintenance access.
Decide whether the application requires routine hygienic sampling, sterile sampling or aseptic sampling.
Confirm whether the valve is cleaned by external flushing, CIP, steam sterilization or a dedicated SIP sequence.
Select manual operation for local sampling or pneumatic operation for automated and repeatable sampling cycles.
Check process medium, temperature, chemicals and required membrane or seal compound before ordering.
Each product family serves a different level of process control. The table below is a practical selection guide rather than a substitute for the OEM datasheet and final engineering review.
| Selection Criterion | Keofitt W9 | Keofitt Basix | Alfa Laval Unique Sampling Valve | Alfa Laval SB Membrane Valve |
|---|---|---|---|---|
| Typical use | High-integrity hygienic or aseptic sampling | Routine hygienic sampling | Hygienic process sampling with size and actuator options | Membrane-isolated manual or pneumatic sampling |
| Operation | Manual or pneumatic, depending on configuration | Generally simple manual configuration | Manual or pneumatic | Manual, manual + microport or pneumatic |
| Sterilization potential | Strong option for steam-sterilizable systems | Application-specific; confirm exact configuration | Available with steam-related accessories and double-seat designs | Confirm membrane and installation suitability |
| Spare-part focus | Membranes, seals, actuator parts and service kits | Simple service components and complete valve references | Actuator, membrane, body, handle, accessory and service-kit selection | Membrane packs, spring, plunger, O-rings and service kits |
| Best selection basis | Required sample integrity and sterilization sequence | Simple routine sampling duty | Valve size, seat design, actuator and accessory package | Manual/pneumatic design and membrane identification |
These terms are often used interchangeably, but they describe different control levels. The valve configuration and operating procedure must match the microbiological risk of the process.
Suitable where cleanable product-contact surfaces and controlled handling are sufficient for quality checks, such as routine physical or chemical analysis.
Requires a sterilized sample path and controlled handling to minimize contamination during microbiological sampling.
Requires both a sterilized sample path and operating procedures that preserve sterility throughout sample withdrawal and transfer.
Manual valves are simple and cost-effective, while pneumatic valves improve repeatability and integration with automated sampling or validation routines.
| Criterion | Manual Valve | Pneumatic Valve |
|---|---|---|
| Operator involvement | Local operator opens and closes the valve | Valve can be actuated remotely or by control sequence |
| Cycle repeatability | Depends on operator technique | More consistent opening time and sequence |
| Automation | Limited | Suitable for PLC-controlled sampling |
| Maintenance complexity | Lower | Higher due to actuator seals, air fittings and control components |
| Best use | Occasional local sampling | Frequent, validated or automated sampling |
Seat configuration affects isolation, sterilization options and accessory selection. Always confirm the exact valve drawing before ordering bodies, actuators or service kits.
| Feature | Single Seat | Double Seat |
|---|---|---|
| Construction | One main sealing interface | Two sealing interfaces with an intermediate chamber or defined flow path |
| Complexity | Simpler | More components and more specific spare-part selection |
| Cleaning and sterilization flexibility | Suitable for many routine duties | Often selected where enhanced isolation or steam routing is required |
| Ordering risk | Lower when size is confirmed | Higher if actuator, body and accessory arrangement are not identified |
Membrane life depends on product chemistry, temperature, steam exposure, cleaning agents, pressure cycling and storage conditions. Never select a membrane only by color.
| Material | General Strengths | Typical Limitations | Ordering Note |
|---|---|---|---|
| EPDM | Common in hygienic processing; good resistance to hot water and many cleaning solutions | Not suitable for every oil, fat or hydrocarbon exposure | Confirm membrane color and bushing identification |
| Silicone | Flexible and suitable for selected temperature-sensitive hygienic duties | Mechanical wear and chemical compatibility must be reviewed | Confirm bushing color and exact OEM reference |
| NBR / BUNA | Useful in applications involving oils and fats, depending on process conditions | Steam and high-temperature resistance may be more limited than EPDM | Do not substitute BUNA and SFY service kits |
| SFY / special compounds | OEM-specific compound for defined legacy valve configurations | Material meaning and compatibility must be confirmed from OEM documentation | Order only against the exact valve family and part number |
Sampling quality depends heavily on where and how the valve is installed. A well-selected valve can still produce unreliable samples if the branch, orientation or surrounding pipework creates product retention.
Install the valve as close as practical to the active product flow and avoid long stagnant branches.
Orient the sample path so condensate, rinse water and residual product can drain after cleaning or steaming.
Leave enough space to remove the actuator, handle, membrane, cap or service components without disturbing pipework.
Do not place the sample point where separation, sedimentation, air pockets or product stratification can occur.
Use the correct cap, hose, quick connection or sterile collection arrangement to protect the sample path.
For weld-in bodies, use qualified hygienic welding and inspect the internal finish and distortion around the valve seat.
A sampling valve should be included in the cleaning and sterilization strategy of the process line. The sequence must clean both the process-facing seat and the sample outlet path.
| Stage | Engineering Objective | Key Verification Point |
|---|---|---|
| Pre-rinse | Remove loose product residue from the valve seat and outlet path | Confirm flow reaches all product-contact surfaces |
| Caustic or detergent wash | Remove organic fouling and product films | Confirm chemical compatibility of membrane and seals |
| Intermediate rinse | Remove cleaning chemical before the next step | Check conductivity or validated rinse endpoint where required |
| Acid wash, where used | Remove mineral deposits | Confirm valve materials and elastomers tolerate the chemistry |
| Final rinse | Prepare the valve for production or sterilization | Ensure no retained liquid remains in poorly drained sections |
| SIP / steam sterilization | Sterilize the sample path and relevant chamber | Verify time, temperature, condensate removal and valve position |
Replacement intervals should be based on cycle count, process conditions, sterilization exposure and inspection findings rather than on calendar time alone.
| Inspection Item | What to Check | Typical Action |
|---|---|---|
| Membrane | Cracks, permanent deformation, discoloration, swelling or loss of flexibility | Replace with the exact material and bushing version |
| O-rings and seals | Flattening, cuts, hardening, chemical attack or leakage marks | Replace with the correct service kit or OEM seal reference |
| Spring | Corrosion, fatigue, deformation or inconsistent closing force | Replace spring and confirm plunger compatibility |
| Plunger / spindle | Scoring, grooves, deposits, wear and correct generation | Replace when wear affects movement or spring compatibility |
| Actuator | Air leakage, slow movement, incomplete stroke or unstable operation | Inspect air supply, ferrules, nuts, O-rings and service kit |
| Caps and outlet accessories | Damaged chains, missing O-rings, loose fittings or contaminated surfaces | Replace and restore hygienic protection |
Troubleshooting should begin with the valve family and operating principle. Similar symptoms can have different causes in manual, pneumatic, membrane and double-seat designs.
| Observed Problem | Possible Cause | Recommended Check |
|---|---|---|
| Valve leaks after closing | Damaged membrane, worn seal, deposits on seat or weak spring | Inspect membrane, seat, spring and service-kit parts |
| No sample flow | Blocked outlet, incorrect valve stroke, plugged microport or closed downstream accessory | Inspect outlet path, plunger movement, cap and microport components |
| Slow pneumatic opening | Low air pressure, restricted air line, damaged O-rings or worn actuator components | Check air supply, ferrule sets, nuts, actuator seals and service kit |
| Valve does not close reliably | Incorrect spring/plunger combination, spring fatigue or product deposits | Check groove pattern on plunger head and replace matched spring/plunger set |
| Repeated contamination of samples | Incomplete sterilization, dead leg, poor drainage or contaminated outlet handling | Review installation, SIP sequence, condensate drainage and sampling procedure |
| Membrane fails too frequently | Wrong compound, excessive steam exposure, chemical incompatibility or installation damage | Confirm material, cycle conditions and correct assembly method |
| Wrong spare part received | Valve identified only by appearance or incomplete model information | Provide OEM number, valve family, size, actuator type, photos and drawings |
A complete identification package significantly reduces the risk of supplying the wrong membrane, actuator, body, service kit or accessory.
Provide valve family, OEM part number, actuator type, valve size and clear photographs.
