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.

This panel provides a pneumatic signal to control a drain 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 exceeds the high level sensor. A local indicator provides status of the output pneumatic signal.

This panel controls a liquid level within the deadband of a single pneumatic float valve. It can be configured for pump-up or pump-down control when used in conjunction with a normally closed pneumatic float valve (pump down) or a normally open pneumatic float valve (pump up). The dead-band of the pneumatic float valve is approximately ¼” – ½”.

This panel indicates if a low liquid level condition exists when used in conjunction with our normally open pneumatic float valves. It is an all pneumatic device. It is for indication purposes only.
