Compact Rupture Disc UKB LS

UKB LS RUPTURE DISC

The UKB LS is made up of a customizable housing, a reverse acting rupture disc and a three-section knife. When the defined burst pressure is reached, the rupture disc is pressed against the knife and opens. This design provides the lowest possible burst pressures while at the same time offering good vacuum resistance even up to high vacuum conditions. The rupture disc and housing are micro-welded and all elements are made of metal. This ensures maximum leak-tightness. Leakage rates of up to 10^-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 and are listed in the table below. Please note that the values stated here are for guidance only. The true values are heavily dependent on the specified housing geometry.

Your advantages:

Maximum leak-tightness.
Also suitable for high vacuum applications.
Out of this world: these rupture discs even protect space satellites – so you can be confident they will function reliably

H is the minimal standard dimension. This dimension might be higher if a edgewise threaded connection in the process-averted part of the housing, in case of using flanges with tongues and groves or in case of ledge and recess is requested. *Replaces DIN 2631 and following. Different sizes, pressure classes, temperatures, materials and fittings available on request.
