O'Keefe Controls Co. Wide Band Level Control “Pump Up” OKC-2291

This panel provides a pneumatic signal to control a fill valve or air operated pump to maintain a liquid level between two sensing points. It uses a normally closed float valve (OKC-1536-2 or OKC-1570-2) to detect the high liquid level point and a normally open float valve (OKC-2250-2) to detect the low liquid level point. The pneumatic output is active when the liquid level falls below the low level sensor. A local indicator provides status of the output pneumatic signal.
