The 812 series for protection of pressure vessels and pressure systems features a wide range of seals. Customers can choose between four different seal variants for different applications. However, the choice of sealing does not depend solely on the medium used and the sealing requirements. In the data sheet, the respective pressure ranges for the individual seals have now been added, as not every seal can withstand pressures of up to 50 bar. Only the PTFE seal guarantees a reliable seal at pressures above 30 bar. NBR, FKM and EPDM seals reliably seal up to 30 bar.
The atmospheric discharge safety valve is now also equipped with the Italian RINA shipbuilding approval.
