Operation
Installed downstream from the air-oil separator, the Blow Down Valve provides two functions:
- At start up, the value closes to permit the air-oil separator pressure to build up.
- At shut-down, when a pressure is applied, the valve opens to bleed the air-oil separator to atmosphere.
The blow down valve may also be used as a by-pass valve to bleed air through the compressor at start-up.
