1、 Product Overview

This quantitative sampling valve is designed for safe and accurate collection of fluid samples under vacuum and shock prone conditions. It adopts a unique 180 degree rotation opening method and anti impact structure, which can effectively avoid medium splashing and cavitation, ensuring the safety of operators and the representativeness of samples. Widely used in industries with high safety requirements such as hazardous chemicals, pesticides, pharmaceuticals, biotechnology, etc.

2、 Product Features

Vacuum applicability: The special design ensures that the valve can still work normally in a vacuum environment, avoiding air from entering and contaminating the sample.

Anti impact design: Built in buffering device can effectively alleviate medium impact, prevent valve damage and medium splashing.

Safe quantitative sampling: Accurately control the sampling volume to avoid waste and safety hazards caused by excessive sampling.

180 degree rotation opening: Easy to operate, only need to rotate 180 degrees to complete sampling, reducing operating space.

Hygiene grade design: Complies with hygiene standards such as GMP and FDA, is easy to clean and disinfect, and meets the requirements of the sampling environment.

Diverse materials: The main components such as valve body and valve core can be made of 316L stainless steel, PTFE, PEEK and other materials according to the characteristics of the medium, to meet special requirements such as corrosion resistance and high temperature resistance.

3、 Working principle

1. Closed state: The valve core is tightly attached to the valve seat, isolating the sampling chamber from the pipeline system.

2. Sampling preparation: Rotate the handle 180 degrees, lift the valve core, open the channel between the sampling chamber and the pipeline system, and allow the medium to flow into the sampling chamber under the pressure difference

3. Quantitative sampling: After the sampling chamber is filled with the medium, rotate the handle 180 degrees in reverse, close the valve core, cut off the flow of the medium, and complete quantitative sampling.

4. Sample collection: Open the sampling port and collect the medium inside the sampling chamber into the sample container.
