Hydrogen Service Ball Valves (H)
Habonim's hydrogen service ball valves are designed and tested to provide safe and durable
use within diverse hydrogen applications and address some leading industrial standards. With
decades of proven safe and long-lasting use in hydrogen applications Habonim Hydrogenservice ball valves delivers reliability and integrity for industrial demanding applications.
Habonim is offering a full range of ball valves for hydrogen-use based on the legacy products
families to cover low to very-high pressures, shut-off or control use, regular, multiport, Double
Block & Bleed or custom-made designs, valve automation packages and much more.
Hydrogen
Hydrogen light atomic weight and molecule structure turning hydrogen-use equipment
sealing into a challenge requires special designs, mechanisms and expertise. Hydrogen is
highly combustion and flammable making leakage prevention an essence for safety and
integrity of systems. In addition materials selection should be considered to prevent effects
such as Hydrogen Embrittlement (HE).
Design
Habonim Hydrogen-use ball valves incorporate some design elements to best accommodate
the hydrogen media:
Double Stem Sealing
Habonim HermetiX patented stem seal is used with additional O-ring sealing.
The HermetiX polymeric, non-graphite stem seal design is certified for ISO 15848-1 and
API641 fugitive emission prevention standards, tested with He.
An additional O-ring stem seal is added as additional sealing point.
This design has been successfully tested for 100,000 open/close cycles under pressure
without any maintenance or seals replacements and well performs in demanding hydrogen
applications for decades.
O-ring
HermetiX
Hydrogen-use material compatibility
All material used for the valve constructions are specified for safe use with hydrogen media.
Metallic materials to be used in the valves are selected to withstand the hydrogen embrittlement
effects and are compatible for hydrogen use.
Testing & Certifications
Some of the ball valves series are tested or certified for specific standard relevant for hydrogen
use such as:
ISO 19880-3:2018 Gaseous hydrogen – fueling stations valve
TPED / TPE - – Transportable Pressure Equipment Directive
Marine classification (on demand): DNV GL, LR, BV, ABS, KR, RINA
