Johnson Controls Pool Pressure Switches

Overview

The JOHNSON CONTROLS F261MAL-V01C is a paddle-type flow switch designed to detect fluid flow in piping systems carrying water, ethylene glycol, swimming pool water, lubricating oils, or other nonhazardous fluids. Part of the F261 Series, it uses a paddle mechanism to sense flow conditions in pipe sizes greater than 1 inch trade size. The enclosure meets NEMA Type 3R and Type 4 ratings, making it suitable for both indoor and outdoor installations. Maximum fluid pressure is rated at 290 psig, and the Viton diaphragm construction supports use in chlorinated and chemically treated water lines. Licensed HVAC and mechanical contractors typically specify this switch for hydronic, pool, and fluid-handling systems. The F261MAL-V01C is applied in residential and commercial piping systems where flow confirmation or flow-loss protection is required. Typical installations include chilled water loops, hot water heating systems, swimming pool circulation lines, and lubricating oil circuits. The paddle sizing accommodates pipe sizes greater than 1 inch trade size, covering a broad range of terminal equipment and fluid-handling applications. Low-flow models within the F261 Series can actuate with less than 1.0 GPM (3.8 L/min) for water or 9.0 GPM (34.1 L/min) for steam, though the specific actuation threshold for this model should be confirmed against the F261 Series product bulletin.
