Working Principle

Sample valve

When Turn the hand wheel clockwise, the valve shaft and seal rise up. At this time, valve is open for sampling. 

When turn the hand wheel anti-clockwise, the valve shaft and seal go down, at that time, the valve is closed.


Yogurt sampling valve

The valve seat opens inside so that it can avoid opening by accident due to much pressure in the pipes.
The valve is nommally closed (through close of spring).the valve is open as soon as pushing the handle with hand and closed whenloosing up.
The design of completely drainage water is to avoid remains inside the valves

Sampling Valve simple structure, beautiful shape, quick to install and uninstall, flexible operation. On many occasions which need frequently chemical analysis of samples, special sampling valve will be used


The fluid resistance is small, safe and reliable to use

It is typical sampling and good repeatability to sample

Prevents secondary contamination and is suitable for bulk or trace sampling.

It can also be assembled at the bottom of storage tanks or pipelines to discharge residues
