Pilot valve is set at standard setting of 95 115 psi or valve can be field adjustable.
Blow down simply means that any air pressure inside this pipe is blown down to 0 bar pressure this to help the compressor on start up.
To get to the heart of the matter inspect the system for leakage valve wear and instrument problems.
On shut down the pipe between the reciprocating piston compressor and the air tank the discharge pipe is blown down by the blow down valve what else.
Pressure relief valves can be used wherever a low flow variable pressure relief valve is required.
