About Atmospheric Dumb Controller

This tool serves to stabilize the pressure oulet of Boiler heading to Cargo Tank, throwing excessive pressure generated in the boiler flue to Exit Boiler Tank further into the Boiler Feed Water Tank. 

Atmospheric Dump Valve

In the process of the system controller using the Atmospheric Dumb sens received from Steam boiler pressure pipe itself in the range of 0-30 kg / cm2 which then triggers Men- output air pressure of Automatic Controller toward the diaphragm Control Valve. 

In a state of excess pressure in the boiler, the steam pipe Control Valve will open, in a state of normal pressure will be back closed.
