Air circuit
for oil free screw compressors
Compressor capacity must be regulated whenever it exceeds current demand. HOERBIGER suction control valves regulate compressor suction volume and close the suction duct during off-loading and shutdown. Airflow is straight through the valve so that flow resistance is very low.
HOERBIGER A-type check valve in discharge line to stop backflow when compressor is off.
Intake regulation, on/off with direct linked venting.
Disc type control (DK):
Straight through flow valve with butterfly type control disc.
