Automatic Switchover System Components - See Figures 1, 2 and 3 

The Series 1041 Automatic Switchover System consists of the automatic switchover electronics unit with 

programmable logic controller, a pressure switch and a motorized ball valve for each source, liquid expansion 

chambers with rupture discs to protect liquid pipelines from hydrostatic rupture if liquid is switched, and optional 

manifolds and manifold bypass valves when gas is switched. Pressure switches, motorized ball valves, expansions 

chambers and manifolds are specific to the gas or liquid being dispensed. 

1.4 

Principle of Operation 

The Series 1041B Automatic Switchover System provides for automatic switching with manual override between two 

independent sources of liquid or gas chemical assuring an uninterrupted supply of chemical to liquid vaporizing or 

gas feed equipment. 

The automatic switchover system is suitable for pressure or vacuum operation.
