Sampling Valve

A sampling valve is a specialized valve installed on industrial pipelines or storage tanks, used to quickly and safely extract small amounts of medium samples from the system for component analysis, quality testing, or process monitoring. It combines convenience in sampling with medium sealing.Widely used in industries such as food and pharmaceuticals, petrochemicals, dairy products, and daily chemical products, it is installed at key nodes of storage tanks, reaction vessels, and conveying pipelines to extract raw materials, semi-finished products, or finished product samples, ensuring product quality meets standards while avoiding medium leakage or contamination during the sampling process.

Common Types

  • Threaded sampling valve: simple structure, easy operation, suitable for manual sampling under normal pressure and low pressure conditions
  • Quick installation sampling valve: connected with clamps, easy to disassemble and assemble, suitable for fast sampling in sanitary grade process systems
  • Pneumatic sampling valve: automatic control sampling, fast response speed, suitable for timed sampling in automated production lines
  • Aseptic sampling valve: Built in sterile sealing structure to prevent sample contamination, suitable for pharmaceutical and biotechnology fields

Structural Advantages & Corresponding Benefits

  1. Non dead angle sterile sampling channel structure

  • Special point: The flow channel is made of 316L stainless steel integrated molding, with the inner wall mirror polished to Ra ≤ 0.8 μ m, no residual grooves, and matched with food grade PTFE sealing valve core.
  • Result:There is no residual medium in the sampling, avoiding cross contamination, meeting the requirements of aseptic production, and the sample testing results are more accurate.

  1. Self closing leak proof sampling structure

  • Special point: The valve adopts a spring reset self closing valve core, which automatically closes the flow channel after sampling is completed without additional operation.
  • Result: Completely eliminate medium dripping after sampling, ensure safe operating environment, and reduce material loss.
