- Process monitoring
- Product verification
1.2 Sterilizable Sampling Design
The main advantage of this valve is the ability to sterilize the sampling passage.
Depending on configuration, sterilization can be performed by:
- Flame sterilization
- Steam injection
- Circulation of cleaning media
This provides greater flexibility for different plant hygiene procedures.
1.3 Compact Modular Construction
The valve is designed as a compact sampling unit that can be adapted to different tank and pipeline installations.
Multiple process connections are available, making it suitable for both new equipment and existing hygienic systems.
二、Product Features
2.1 Multiple Sterilization Methods
The valve can be configured for flame sterilization or for sterilization using steam or cleaning liquids.
2.2 Hygienic Construction
A one-piece machined body helps provide a smooth and uniform internal surface while reducing rough weld areas around the outlet.
2.3 Manual or Automatic Operation
Manual and pneumatic versions are available.
Manual versions can use:
- Stainless steel handle
- Plastic handle
- Colored handle options
Automatic versions can be equipped with a compact normally closed actuator.
2.4 Multiple Connection Options
Available connections include:
- Wall weld
- Pipeline weld
- Male threaded connection
- Clamp
- Mini-Clamp
- Micro-Clamp
This makes the valve adaptable to a wide range of hygienic installations.
2.5 Different Seal Options
Various seal combinations are available for different media and operating requirements.
These include configurations based on:
- PFA / EPDM
- PFA / FKM
- EPDM
- FKM
- VMQ

四、Working Principle
4.1 Closed Position
When the valve is closed, the sampling passage is isolated from the process medium.
4.2 Sterilization Before Sampling
Before collecting a sample, the sampling passage can be sterilized according to the installed configuration.
For a single-outlet version, flame sterilization may be used.
For a two-outlet version, steam or cleaning media can circulate through the sampling area.
4.3 Sampling
The operator opens the valve manually or activates the pneumatic actuator.
Product then enters the sampling outlet and can be collected in a suitable sample container.
4.4 Closing
After the required quantity has been collected, the valve is closed.
4.5 Post-Sampling Cleaning
The sampling area can then be cleaned or sterilized again to prepare the valve for the next sampling cycle.
五、Applications
5.1 Food Processing
Suitable for hygienic sampling from food production tanks and processing lines.
5.2 Pharmaceutical Processing
