The Ingersoll Rand 23410798 blowdown valve bleeds off sump/separator vessel pressure when the compressor goes into the unload mode. This depressurizes the system so the compressor is not at full pressure when not running loaded.
The 23410798 valve is installed on the airend. This has separate tubing that connects back to the separator which allows the oil resevoir to be depressurized.
Several of the following series rotary compressors utilized this load solenoid valve however some models did have different valves depending on the year made. Please contact us with your serial number and we can verify this is the correct item for your Ingersoll Rand rotary screw compressor.
