Switchover

Switchover

A device which is used to automatically change the supply of chlorine gas from an active cylinder which has just emptied to a full cylinder. The loss of vacuum from the empty tank causes a valve in the switchover device to change position, shutting off the gas feed from the empty tank and opening the inlet valve of the chlorinator on the full tank. Both single-point and multi-point applications systems use switchover devices.
