COMPRESSOR CAPACITY CONTROL – TURN
VALVE UNITS ONLY
The capacity of the compressor is controlled by the ac-
tion of the Turn Valve and the Compressor Inlet Valve.
The turn valve controls compressor delivery to match
demands of 40% to 100% of the compressor’s maxi-
mum capacity. The inlet valve throttles to control com-
pressor delivery to match demands of 0% to 40% of the
compressors maximum capacity.
