Sanitary Tri-Clamp Sampling Valve
The Sanitary Tri-Clamp Sampling Valve is designed for hygienic sampling from tanks, vessels, and process pipelines. Its sanitary clamp connection provides quick installation and removal, making the valve suitable for processing systems where frequent cleaning, inspection, and maintenance are required.
The valve uses a hygienic membrane sealing design to separate the process medium from the operating mechanism. Samples can be collected during production without dismantling the process line, while the sampling area can be cleaned or sterilized according to process requirements.
一、Product Overview
1.1 Main Function
The Sanitary Tri-Clamp Sampling Valve is used to collect representative samples from hygienic tanks and process pipelines for:
- Quality Control
- Laboratory Analysis
- Microbiological Testing
- Process Monitoring
- Product Inspection
1.2 Hygienic Design
The valve uses a compact stainless steel body with a sanitary sampling passage.
A membrane sealing element isolates the product-contact area from the operating mechanism, helping reduce contamination risk during sampling.
1.3 Tri-Clamp Connection
The sanitary clamp connection allows the valve to be installed and removed without complicated threaded or bolted connections.
This makes inspection, cleaning, and maintenance more convenient.
二、Product Features
2.1 Sanitary Clamp Connection
The Tri-Clamp design provides fast assembly and disassembly and is widely used in hygienic processing equipment.
2.2 Stainless Steel Construction
Product-contact components can be manufactured from SS316L stainless steel for corrosion resistance and hygienic processing applications.
2.3 Membrane Sealing
The membrane acts as a hygienic sealing element between the process medium and valve operating mechanism.
2.4 Sterilizable Design
Depending on configuration, the sampling chamber can be sterilized using steam or alcohol before and after sampling.
2.5 Easy Cleaning
Smooth product-contact surfaces and removable sanitary connections simplify cleaning and inspection.
2.6 Flexible Operation
Manual and pneumatic operating configurations can be supplied according to process requirements.

四、Working Principle
4.1 Closed Position
When the valve is closed, the membrane seals the sampling passage and isolates the process medium from the outlet.
4.2 Opening
The operator opens the valve manually or activates the pneumatic actuator.
The valve stem and membrane move away from the sealing position, allowing product to enter the sampling passage.
4.3 Sampling
A controlled amount of process medium flows through the sampling outlet into the sample container.
4.4 Closing
After collecting the required sample, the valve is returned to the closed position.
4.5 Cleaning and Sterilization
The sampling passage can then be cleaned or sterilized according to the hygiene requirements of the process.
五、Applications
5.1 Food Processing
Suitable for hygienic tanks and process lines used for liquid food production.
5.2 Beverage Production
