Honeywell V4055B1039 Modutrol actuator

Honeywell V4055B1039 actuator — a professional fluid (hydraulic) actuator designed for controlling gas valves in industrial and commercial burner equipment. This model provides slow opening (13 seconds) and instantaneous closing (less than 1 second), which is critical for safe ignition of high-power burners. In warehouse accounting systems, this device is also known under part number 534.712.133. Model V4055B1039/U is a complete analogue of V4055B1039 and has identical technical characteristics. Purpose and compatibility: The Honeywell V4055B1039 (Fluid Power Actuator) is designed to work with Honeywell gas valves of the V5055 series (sizes from 3/4" to 4") and V5097. It is used for remote gas supply control on industrial burners, in boiler rooms, and on process lines. Key applications: Control of natural gas or propane supply on industrial burners. Final gas shut-off in safety systems. Installation on burner panels and gas distribution points (GDP).
