Suction Control for Oil Injected Screw Compressors

Suction control

for oil injected 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.
