GENERAL INFORMATION INSTRUCTION & FEATURES
EX Line blind - offers 100% pipe isolation for severe services
such as extremely high temperature (816℃) / cryogenic condition (-196℃) or gas / liquid containedparticles / polymer applications.
The unique spreading mechanism makes a gap to switch blind plate position in a short time.
Only gasket replacement of blind plate is needed for maintenance.(No internal gasket)
