Puncture Type Sampling Valve

Product Description

The GMK VALVE Puncture Type Sampling Valve is specially designed for safe and contamination-free online sampling from pipelines, reactors, storage tanks, and process systems. The puncture-type structure allows the sampling needle to penetrate a sealed sampling bottle stopper directly, ensuring closed sampling and minimizing operator exposure to hazardous media.

Equipped with an integrated purge function, the valve effectively removes residual process media before and after sampling, improving sample accuracy and reducing the risk of cross-contamination. The valve is widely used in chemical processing, petrochemical plants, pharmaceutical manufacturing, biotechnology, food production, and other industries requiring reliable process sampling.
