Resideo 40003916-526 Replacement Head W/End Switch 24V V8043E5000

The Resideo 40003916-526 Replacement Head with End Switch is a 24V control part used with the V8043E 5000 series zone valves in residential and light commercial HVAC systems. It allows for dependable zone control because it controls the flow of hot water through hydronic heating systems. The end switch built into the valve informs the HVAC system when the valve is wide open, increasing efficiency as the circulator or boiler is only activated when required. This replacement head contributes to optimal temperature control, enhances energy efficiency and increases system life, making it essential in maintaining performance in zoned hydronic heating applications.
