The Tank Bottom Sampling Valve is designed for hygienic sampling directly from process tanks and vessels. Installed at the lower section or bottom of a tank, the valve allows operators to collect representative product samples while also providing the possibility of draining residual media from the tank.
Its compact stainless steel construction is suitable for sanitary processing environments where cleanliness, corrosion resistance, and easy operation are important. The valve can be integrated into storage tanks, mixing tanks, fermentation vessels, and other hygienic processing equipment.
一、Product Overview
1.1 Main Function
The Tank Bottom Sampling Valve is used to extract samples directly from tanks or vessels during production, storage, or processing.
When installed at the tank bottom, the valve can also assist in draining residual product after processing.
1.2 Valve Construction
The valve typically consists of:
- Stainless steel valve body
- Manual operating mechanism
- Valve stem
- Hygienic sealing element
- Sampling outlet
- Tank connection
- Optional flushing or sterilization port
1.3 Installation Position
This valve is designed mainly for:
- Tank bottom installation
- Lower tank wall installation
- Vessel sampling points
- Hygienic processing equipment
二、Product Features
2.1 Tank Bottom Design
The valve is specially designed for installation at or near the bottom of a process tank, allowing convenient sampling and residual product drainage.
2.2 Hygienic Stainless Steel Construction
The valve body is manufactured from SS316L stainless steel, providing good corrosion resistance and suitability for hygienic processing applications.
2.3 Compact Structure
The compact design minimizes installation space and allows integration into tanks and processing vessels.
2.4 Easy Manual Operation
The valve can be operated manually, allowing simple and controlled sample collection.
2.5 Reduced Product Retention
Installing the valve close to the tank bottom helps reduce product retention and allows more complete drainage.
2.6 Easy Cleaning
The hygienic design supports cleaning procedures required in sanitary processing systems.

四、Working Principle
4.1 Closed Position
During normal production, the valve remains closed and isolates the tank contents from the sampling outlet.
4.2 Opening the Valve
When a sample is required, the operator manually opens the valve.
The valve stem moves away from the sealing surface, allowing the process medium to flow through the sampling outlet.
4.3 Sample Collection
A controlled amount of product can then be collected into a suitable sampling container.
Because the valve is positioned near the bottom of the tank, samples can be taken directly from the stored or processed product.
4.4 Residual Product Drainage
Depending on the installation configuration, the valve may also be used to drain residual product remaining at the bottom of the tank.
五、Applications
5.1 Food Processing
Suitable for hygienic processing systems such as:
- Liquid Food Tanks
- Mixing Tanks
- Storage Tanks
- Processing Vessels
5.2 Pharmaceutical Processing
The stainless steel hygienic design is suitable for process equipment requiring controlled and clean product sampling.
5.3 Chemical Processing
The valve can be used for compatible process liquids where stainless steel construction is required.
5.4 Cosmetic Processing
Suitable for tanks and vessels used in hygienic cosmetic and personal care production.
5.5 Biotechnology
The valve can also be used on hygienic tanks and vessels in biotechnology-related processing systems.
六、Available Configurations
6.1 Installation Options
- Tank Bottom Mounted
- Tank Wall Mounted
- Vessel Mounted
6.2 Connection Options
Different hygienic tank connections can be supplied according to installation requirements.
6.3 Sampling Outlet Options

七、Advantages
7.1 Direct Tank Sampling
Samples can be collected directly from the tank without transferring product to another pipeline or vessel.
7.2 Improved Tank Drainage
Tank-bottom installation helps reduce residual product remaining inside the vessel.
7.3 Hygienic Construction
SS316L construction makes the valve suitable for sanitary and hygienic process environments.
7.4 Compact Installation
The compact valve body requires minimal space around the tank.
7.5 Easy Operation
Simple manual operation allows convenient sampling without additional pneumatic or electrical equipment.
八、How to Select
8.1 Confirm Tank Connection
The valve connection should match the tank outlet or welding connection.
8.2 Confirm Product Characteristics
Consider:
- Product viscosity
- Temperature
- Chemical compatibility
- Solids content
- Hygiene requirements
8.3 Select the Installation Position
Determine whether the valve will be installed directly at the tank bottom or on the lower side wall.
8.4 Confirm Cleaning Requirements
For sanitary systems, confirm whether the valve needs additional flushing, CIP, or sterilization capability.
8.5 Confirm Sampling Method
The sampling outlet should be selected according to the required sample volume and sampling container.
九、Maintenance
9.1 Routine Inspection
Regularly inspect:
- Valve stem
- Sealing element
- Sampling outlet
- Tank connection
- Operating mechanism
9.2 Seal Inspection
Replace seals if wear, leakage, or reduced sealing performance is detected.
9.3 Cleaning
Clean all product-contact surfaces according to the hygiene requirements of the process system.
9.4 Connection Inspection
Periodically check the tank connection to ensure secure installation and prevent leakage.
