Vertical Press Type Needle Core Sampling Valve

Vertical Press Type Needle Core Sampling Valve | GMK VALVE

PRODUCT DESCRIPTION

The Vertical Press Type Needle Core Sampling Valve manufactured by GMK VALVE is a high-performance online sampling device designed for safe, accurate, and contamination-free sampling in pressurized pipeline systems.

This valve enables direct sampling from operating pipelines without system shutdown, making it ideal for continuous production environments in chemical, petrochemical, pharmaceutical, and hazardous media industries.

Equipped with an integrated blowdown function, the valve effectively removes residual media after each sampling process, significantly reducing cross-contamination risks and improving sampling reliability. Its puncture-type design allows sealed sampling through bottle stoppers, ensuring sample integrity and operational safety.
