F261KFH-V01C Johnson Controls Flow Switch

Overview

The Johnson Controls F261KFH-V01C is a low-flow model fluid fluid flow switch designed to respond to fluid flow in lines carrying water, ethylene glycol, or other nonhazardous fluids. Equipped with a Type 3R NEMA enclosure, this inline device is suitable for both indoor and outdoor applications where it is protected from weather and splashing water. It features a Viton diaphragm and a high-sensitivity design ideal for monitoring low-flow conditions in commercial and industrial HVAC systems.

Features

• Low-flow operation specifically designed to actuate the switch under low fluid flow conditions
• Viton diaphragm allows for use in lines carrying chlorinated water, treated water, swimming pool water, and lubricating oils
• Type 3R (NEMA) polycarbonate enclosure providing dust and moisture protection
• SPDT switch action integrates seamlessly with building automation systems, boiler controls, and pump circuits

Specifications

• Model: F261KFH-V01C
• Connection Size: 3/4 inch x 3/4 inch female NPTF inlet and outlet
• Maximum Fluid Pressure: 290 psig (20 bar)
• Fluid Temperature Range: -20°F to 250°F (-29°C to 121°C)
• Enclosure Rating: NEMA 3R / IP43
• Electrical Rating: SPDT, 24V to 240 VAC

Applications

• Monitoring low-flow fluid conditions in commercial HVAC and building automation systems
• Pump interlock circuits to prevent pump operation in no-flow conditions
• Boiler controls and fluid chiller systems to reduce the chances of freeze-ups
• Industrial liquid lines carrying nonhazardous fluids, swimming pool water, or lubricating oils
