一．Product Introduction
The plunger sampling valve is a V-type plug shut-off valve. Its structure adopts a double-sealing plunger-type sampling form. This plunger sampling valve is produced by some manufacturers referencing foreign samples. It is mainly suitable for sampling, inspection, and sampling of easy-to-crystallize media in chemical plant reactors, and is specially designed for extracting a certain amount of materials in production to check whether they meet the requirements. Some manufacturers use ball valves instead, but the ball valve structure has dead zones and often clogs, which is very troublesome. The stainless steel plunger sampling valve overcomes this shortcoming of the ball valve. Its principle is based on the plunger valve, with a true double-sealing system, combining the structure of the Y-type shut-off valve and the top-mounted discharge valve. There is no dead zone, no residue, and leakage can be avoided.
