SDX Type

GENERAL INFORMATION

INSTRUCTION & FEATURES

SDX Type special blind valve has developed for the requirement of isolation under pressure
open/close position can be changed with soft seals (special sealing kids) achieve positive isolation of liquid / gas fluids without depressurize the pipe line
dual gear-set actuator allows no friction during operation and soft seal can make perfect isolation.
