The unique geometry of the HermetiX (Habonim patent) ensures zero leakage and a maintenance-free product life. The flexible X shape of the HermetiX allows a dynamic sealing arrangement in case of stem side load occurrence. Sealing is improved while increasing pressure. Stem packing integrity is maintained due to relaxation of stem spring preload due to erosion of soft parts. This is a great advantage over linear motion valves like globe valves which by definition are prone to leakage and require a rigorous, time consuming, maintenance operation and product loss.

This new design makes Habonim Cryogenic Ball Valves unmatched in reliability, stability and most importantly, safety. The valves are for use in separation plants, LNG storage, distribution and transportation, aerospace, petrochemical and mechanical industries.

The valves are made of Austenitic Stainless Steel 316 / 316L and are available in ¼` – 6` (DN6 – DN150), with Standard Bore or Full Bore. End Connections: Flanged, Screwed, Butt weld.
Working pressure ranges from 0 to 64 bar (928 psig), working temperature ranges from -269 C to +200 C (-452 F to 392 F).

Where automation is required, the cryogenic ball valves are available with Habonim`s unique pneumatic Compact 4-piston actuator. A limit switch or positioner can be mounted on the top actuator face.
