Working pressure tolerances of 90% - now also for high-pressure applications > 400 bar g.  

The HPRRD reverse rupture disk offers a durable and sustainable solution for high-pressure applications with pulsating process conditions. The new design dispenses with predetermined breaking notches or other mechanisms that impair fatigue strength.   The compact design requires no additional support structures and guarantees direct installation in the on-site installation system. Independent and flexible machining of the outer contour allows unlimited freedom for the connections and sealing surfaces.  

Burst pressures from 400 to 4000 bar g with a tolerance of up to ± 2 % of the nominal burst pressure can be realized thanks to consistently precise manufacturing and guarantee a reliable safety function from -5 to 350 °C. 

When triggered, the bursting diaphragm ruptures as a whole and releases the entire relief cross-section. This enables the process pressure to be relieved safely and quickly. 

The unnotched design of the new ST-HPR high-pressure reverse rupture disc enables high pulsating working pressure tolerances of 90 %. As the first reverse rupture disc in the REMBE® universe, no mechanical weakening by blades, for example, is required for opening. The compact design and machining from solid material guarantee almost limitless freedom of shape of the outer contour - whether conical or flat sealing. Burst pressures of 400 to 4000 bar g with a tolerance of up to ± 2 % of the nominal burst pressure can be achieved through consistently precise manufacturing and guarantee reliable opening behavior from -5 to 350 °C. When triggered, the bursting diaphragm ruptures as a whole and releases the entire cross-section. This enables the process pressure to be relieved safely and quickly.
