Inverted rupture disc UKB LS

reverse actingmetalcustom

The UKB LS comprises a customisable housing, a three-section knife and a reverse acting rupture disc. When the defined burst pressure is reached, the rupture disc is pressed against the knife and opens. This design provides the lowest burst pressures while at the same time offering good vacuum resistance even up to high vacuum conditions. The rupture disc and the housing are micro-welded and all elements are made of metal. This ensures a maximum leak-tightness. Leakage rates of up to 10 to the power of -10 are possible. With a wide array of available connections, we supply the ideal pressure relief unit for every application – even for ultra-clean processes. Despite its individuality, a number of “standard” sizes have become established for UKB LS over the last few decades. These are for installation between industry standard flanges. Advantages -Maximum leak-tightness: also for helium. -Also suitable for high vacuum applications. Mechanism When the defined burst pressure is reached, the rupture disc is pressed against the knife and opens.
