|Fluid Media||Chlorine Gas|
|Temperature||-40 C to 74 degree C|
In order to have uninterrupted chlorine gas supply to chlorination system necessary manifolds.Motorised valves and control panel are provided. Chlorine tonner is connected to the Pressuremanifold in which pressure gauge and pressure switch, it indicates the chlorine tonner pressure and pressure switch actuate the electrically operated ball valve.
Filled tonner connected to the opened manifold. All tonners valve are open so that manifolds are under the pressurized condition. Switch on the auto change over the panel and keep the selector switch in the auto mode now as soon as the panel is energized electrically operated valve manifold –I will open first. Even though manifold –ll is pressurized, manifold –ll side valve will not operate due to interlock system.
As the plant is in operation, chlorine gas will be consumed and tonner pressure may be coming down.When pressure switch actuator and the tillalarm will come and electrically operated ball valve on manifold –l will close and valve on manifold – ll will open simultaneously.
