OKC-3171 Wide Band Level Control “Pump Down”: This panel provides a pneumatic signal to control a drain valve or air operated pump to maintain a liquid level between two sensing points.A local indicator provides status of the output pneumatic signal.
The pneumatic output is active when the liquid level falls below the low level sensor. 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. OKC-2291 Wide Band Level Control “Pump Up”: This panel provides a pneumatic signal to control a fill valve or air operated pump to maintain a liquid level between two sensing points.OKC-2290 Low Level Indicator: This panel indicates if a low liquid level condition exists when used in conjunction with our normally open pneumatic float valves.OKC-2289 High Level Indicator: This panel indicates if a high liquid level condition exists when used in conjunction with our normally closed pneumatic float valves.Our offering of pneumatic float valve level indicators and controls include: Indicator Panels Indicator panels display either high or low liquid levels, while controls provide a pneumatic output to control liquid level between two points. Pneumatic Float Valves - Level Indicators and Controls Normally open pneumatic float valves provide a pneumatic output on liquid level fall. OKC-2271-2: This top-mounted pneumatic float valve features a normally open output (normally passing).OKC-2250-2: This side-mounted pneumatic float valve features a normally open output (normally passing).Normally closed pneumatic float valves provide a pneumatic output on liquid level rise. OKC-1570-2: This top-mounted pneumatic float valve features a normally closed output (normally non-passing).OKC-1536-2: This side-mounted pneumatic float valve features a normally closed output (normally non-passing).Our magnetic float valves detect liquid levels inside closed or vented vessels. Pneumatic Float Valves - Horizontal & Vertical Mounting Our pneumatic float valves are available in several variations with accessory options to provide customized solutions for your liquid level application.
