application

  Sterile sampling valves are primarily used for material sample collection in tank equipment or piping and require sterilization prior to and after each sampling. No dead ends, complete sterilization, continuous sampling and sterile sampling at any time. Widely used in food, wine, beverage, dairy products, toothpaste cosmetics, bio-pharmaceutical and other industries.

working principle

This aseptic sampling valve is mainly divided into hand wheel, bracket, valve core, spring, valve body, diaphragm seal ring. When in the closed state, rely on turning the handwheel counterclockwise to loosen the valve core (until the handwheel is in the neutral position), and the sealing rubber head is pressed by the valve core to the inlet of the valve body material to achieve the sealing effect; if sampling is required, Vapor or other sterilizing medium is introduced from one of the (usually the lower) sampling ports, and the entire sample chamber is filled and discharged from the other sampling port. After a certain period of time, the sample chamber and the sampling port are sterilized; By rotating the hand wheel clockwise, the valve core is pulled, so that the sealing rubber head is detached from the inlet of the valve body material, so that the sample flows out of the tank through the sample chamber and is collected from the sampling port; after the sampling is completed, the hand wheel is rotated counterclockwise. Relax the valve core, and press the sealant head to the inlet of the valve body through the valve core again; pass the clean water to drain the residual liquid in the sample chamber. (If the sample is a clean medium such as sterile water, this step can be Omitted), then inject the sterilizing medium to seal and keep it for the next sampling.
