Honeywell V4055D1043 Gas Valve Actuator 13-Second

The Honeywell V4055D1043 is an on-off fluid power gas valve actuator engineered for commercial and industrial gas burner, boiler, and industrial furnace applications. It provides a 13-second opening time at 60 Hz with a maximum 1-second closing time, meeting code and insurer requirements for fast-acting safety shutoff service. The actuator includes an SPDT proof-of-closure switch and valve seal overtravel interlock, mounts to a damper shaft, and operates across a temperature range of -40°F to 150°F. It is rated NEMA 1 (IP30) and carries UL, CSA, and FM certifications for natural gas fuel applications. This unit is intended as an OEM replacement and requires professional installation. It is designed for use with a V5055 or V5097 gas valve and a 7616BR damper crank arm. Typical failure symptoms warranting replacement include the actuator failing to open, slow opening, incomplete closing, proof-of-closure switch failure, or a gas valve sticking in position.
