Hermetix™ stem seal (zero emission)
Hermetix™ stem seal
(zero emission)
As world focus turns to preserving our environment,
Habonim introduces its new series of ZERO-Stem-LEAK
valves based on the HermetiX™ technology.
HermetiX is a patented stem seal designed to reduce to a
minimum stem leak and provide maintenance-free service.
Named after its X-shaped design,
the HermetiX's™ dynamic action enables improved
performance as pressure increases.
The New Habonim Minimum-Stem-LEAK valves meet ISO
15848-1 standard for fugitive emission, covering
performance CO5 (5K cycles), and class BH for
temperature ranging from -29 C to +200 C.

Why HermetiX™ zero leakage stem seal ?
• Overview of Environment and Safety issues and
related Standards
• Minimizing Fugitive Emission Minimizing/Preventing
Environment Emissions
- ISO 15848
- TA Luft
ISO 15848-1
ISO 15848-1 standard requirements are stricter
than the guidelines of TA-Luft and the
corresponding VDI-guideline
(VDI 2440).
As a result, Habonim company have decided to
obtain the ISO 15848-1 certificate for all its
commodity ball valve series .
ISO 15848-1
• ISO 15848-1 standard sets specific detailed tests for determining leakage and the creep behavior of valves.
• Cycle test under temperature fluctuations. • Replicating site conditions more accurately.

Why non-graphite
Hermetix™ fire safe stem design ?
