ULTRX?*** and STAR X(TM)*** Rupture Discs - High performance scored, reverse acting designs.

The ULTRX and STAR X rupture discs are scored, reverse acting designs that feature:

Operation to 90% of the rated burst pressure.
A holder assembly providing exceptional flow characteristics
when used in SRV isolation applications.
Encapsulating rings on the rupture disc to eliminate torque sensitivity.

The ULTRX rupture disc can be used in practically any processing system. It performs in gaseous, partial gas/liquid, or even 100% fully liquid systems.
