Puncture Needle Sampling Valve

Product Description

The Puncture Needle Sampling Valve manufactured by GMK VALVE is designed for safe, accurate, and contamination-free sampling from pressurized pipelines, reactors, storage tanks, and process systems. The puncture needle structure allows samples to be collected through sealed sample bottle stoppers, minimizing exposure to hazardous media and ensuring sample integrity.

Designed for online operation, the valve enables sampling without shutting down the process, improving efficiency and reducing production interruptions. An integrated purge function removes residual media before and after sampling, preventing cross-contamination and enhancing sampling accuracy.

The valve is widely used in chemical processing, petrochemical plants, pharmaceutical manufacturing, food and beverage production, biotechnology facilities, and hazardous chemical handling systems.
