Use
The most basic function of a sampling valve is to collect samples. By opening and closing the sampling valve, the required sample can be taken out of the pipeline or container for subsequent analysis, testing, monitoring, and other purposes. Sampling valves can be installed on pipelines or containers, and can be set according to the type and location of samples to be collected, ensuring that the collected samples are representative and accurate.

Structure
1. Valves mainly consist of valve body, valve seat, valve stem, valve core, cover, valve cover, etc.
2. The flow characteristics of the valve are equal percentage, straight line, and equipped with electric or pneumatic actuators.
Install
1. The door should be installed vertically on a horizontal pipeline.
2. It is necessary to install according to the medium flow direction indicated by the arrow.
3. During installation, ensure that the opening and closing positions of the electric actuator are consistent with the opening and closing positions of the valve window.
