Supplementary loading system for operation at up to 97% of the maximum permissible operating pressure.
Higher process productivity due to operation of the system to be protected closer to the maximum permissible operating pressure (PB) (up to 97%)
less media loss when opening and closing the Safety valve. Both opening and closing times are shortened
reduced noise emissions, as the opening and closing times of the Safety valve are shortened
Complete tightness up to set pressure - The Safety valve remains tight even at pressure peaks that occur below the set pressure.
less wear of the Safety valve, as no simmering occurs before the Safety valve responds
