Aim to avoid flange single side press mode, this mode results in the flange pad failure due to the excessive extrusion.
Four synchronous system aim to avoid flange single side press mode, this mode results in the flange pad failure
due to the excessive extrusion. And then lead to leakage. Four synchronous system refers to four KATTOR wren
ches are used synchronously connecting to one KATTOR hydraulic pump. According to the hydraulic principle, f
our wrenches work in the same time., output the setting torque in the same time, that can realize the flange shut
off parallelly. The torque precision could reach±3%.the efficiency of four synchronous system is four times of sin
gle system.
