Azbil 700 series - Supply Bypass

3-12
3-2-3 Supply Bypass
Supply bypass allows the valve to be fully closed and opened and enables operation with
the regulator.
(For double-acting actuators, the valve can only be fully opened or closed.)
Cautions
When the supply bypass operates, it is dangerous because the valve moves. Be
prepared in advance to prevent injury and effects on the process when the valve moves.
