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 maintenanc
