GENERAL INFORMATION

INSTRUCTION & FEATURES

EX Type blind valve offers 100% isolation for severe service with extrem temperature and pressure
/or cryogenic (-196℃) application.
Sample picture shows an application at 1500Ｆ(816℃) 2500 LBS, DN 500
No internal gasket with simple structure minimize contact surface with extream media and unique spreading mechanism
make a gap to switch blind plate position in a short time.
Strong torque for tighteness with solid structure enable to isolate severe pipeline with safe.
Only gasket replacement of blind plate is needed for maintenance.
