Sgm-k manual quick opening sterile sampling valve (PTFE)

application

The sterile sampling valve is mainly used for the collection of material samples in tank equipment or pipeline, and requires sterilization before and after each sampling. No dead angle, complete sterilization, can be continuous and sterile sampling at any time. Widely used in food, wine, beverage, dairy products, toothpaste, cosmetics, biopharmaceutical and other industries.

working principle

The aseptic sampling valve is mainly divided into handwheel, bracket, valve core, steel ball, valve body and diaphragm seal ring. When it is in the closed state, the valve core is pushed by turning the hand wheel clockwise, and the sealing head is pressed on the material inlet of the valve body by the valve core to achieve the sealing effect; if sampling is needed, steam or other bactericidal media are introduced into one (generally the lower) sampling port to fill the whole sample chamber and lead it out from another sampling port. After a certain period of time, the The sample chamber and sampling port are in aseptic state; then, rotate the hand wheel anticlockwise to pull the valve core in and out to separate the sealant head from the material inlet of the valve body, so that the sample flows out of the tank through the sample chamber and is collected from the sampling port; after sampling, rotate the hand wheel clockwise to push the valve core, and press the sealant head on the material inlet of the valve body again through the valve core; pass through the clean Water will discharge the residual liquid in the sample room (if the sample is sterile water and other cleaner media, this step can be omitted), and then inject the sterilization media for sealing and retention, waiting for the next sampling.
