A fire-safe AND non-graphite valve?

Today there is an ever increasing demand for quality fire-safe valves due to a number of factors, which include:

  • Rising insurance costs for liability due to personal injury or loss of life
  • Property damage
  • Tighter environmental and safety regulations
  • Loss of materials through leakage
  • The high cost of system shutdown and loss of product

Continued development of the HermetiX technology led to Habonim’s revolutionary graphite-free fire-safe stem-seal design. A polymer-based stem seal and a unique trim construction holds the stem aligned and preloaded even after a fire.

This unique fire-safe valve design specially designed for the API Pharmaceutical industry includes a non-graphite HermetiX stem seal consisting of a virgin PEEK thrust bearing and anti-abrasion ring, and a stem seal made of TFM material. Both virgin PEEK and TFM are FDA approved.

A double body seal set is comprised of an internal PTFE body seal facing the media, and an external graphite seal to withstand the fire. This configuration effectively isolates the graphite seal in a dry cavity, preventing it from coming in contact with the media, ensuring a high level of purity for the valuable media.
