Anti-Blocking Plunger Sampling Valve

PRODUCT DESCRIPTION

The GMK VALVE Anti-Blocking Plunger Sampling Valve is designed for safe, accurate, and leak-free sampling of viscous, high-temperature, and hazardous media in pipelines and storage tanks.

It is widely used in petrochemical, chemical, pharmaceutical, and industrial process systems where sampling of flammable, explosive, or high-viscosity media is required.

The valve features a plunger-through-body structure that ensures no residual liquid or gas remains after sampling, effectively preventing cross-contamination and environmental pollution. It is suitable for demanding applications where safety, accuracy, and reliability are critical.

Optional cooling and purging functions can be added according to process requirements, making it suitable for high-temperature and condensation-prone media.
