Pressure Release Valve
These are the most common silo accessories which help in maintaining a pre set pressure level in the silos. These valves start operational once the inside pressure of silos reaches the pre set pressure limit. As soon as the pressure exceeds the pre set value, these valves starts operational and helps in discharge of this high pressure
Hence preventing the breakdown of silo filters because of any excessive pressure.
The powder is transferred from feeding pumps/ bulkers to silos with high pressure. There can be a possibility of transferring of air instead of powder due to absence of powder in the bulkers, resulting in having high air pressure in silos. This can result in damage of silo or silo filter in the absence of these pressure relief valves
