Blow Down Valve (P)
- This (two-way solenoid) device vents compressed air from the air/oil sump.
During compressor operation (e.g., compressors are running or they have temporarily stopped due to line
pressure reaching unload pressure); the blow down valve remains energized (closed) and the air/oil
reservoir remains pressurized. When compressor operation is halted (e.g., by use of the red “STOP”
controller button, by loss of electrical energy, or by a shutdown condition), the valve is de-energized
(normally open state) and the air/oil reservoir is blown down.
