DSB-HFKH 1000
Double Safety and Bleed Balve 1000 bar
The DSB Valves by MHA Zentgraf consist of two shut-off valves that reliably isolate storage systems and safely release residual pressure to minimize potential risks and facilitate maintenance tasks at hydrogen refueling stations.
The DSB-HFKH valves use the same sealing concept on the drive shaft and connections as the valves in the HFHK series. This design makes them suitable for high-cycle operations and compliant with service life requirements according to ISO 23826. Additionally, they are ATEX certified and meet the low emission standard DIN EN ISO 15848-1.
For purge connection, there are various options for different internal thread connections or even the possibility of an integrated needle valve. This allows for customizing the DSB valve according to specific requirements and using it flexibly in hydrogen applications.
