Cobra HTHV

The Sentry Cobra HTHV closed loop sampler is specifically designed to provide a safe sampling method for high-temperature high-viscosity applications such as hot oil and slurries. Enclosing the system and allowing the operator to view the process through a viewing window provides extra safety. Designed to the highest quality standards and to the most precise specifications, the Cobra HTHV sampler is ideally suited to use in the petrochemical, refinery, chemical and specialty gas industries.

The Cobra HTHV sampler is designed to address the problems that temperature can create when trying to secure accurate representative samples. By steam jacketing the sample loop, the problems of plugging and cold spots are effectively prevented, while the inclusion of a multi-turn valve with a hardened seat means the operator can throttle the sample flow adequately to secure the sample safely.

Designed for the following applications: Hot oil, Residual oil, Vacuum tower bottoms, Slurries, Asphaltenes


  • Safe sampling for high temperature high viscosity applications
  • Flow-through HTHV valve allows constant representative process flow for immediate sampling, and prevents process from stagnating and clogging
  • Available steam jacketing of entire sample to prevent plugging or cold spots
  • Multi-turn valve with hardened seat allows throttling of sample flow
  • Replaceable steam-jacketed stinger
  • Enclosure with viewing window protects operator during sampling operation
  • Big bore HTHV valve available with 1/4‑inch orifice to handle larger particles and higher viscosity flows
