## Description

for v8043e1012 Zone Valve Honeywell, 40003916-026 Power Replacement Head, 40004850-001 (Lid Model) 2-Way 4-Wire, Normally Closed 24Vac 50/60Hz 9" Leads with End Switch for Honeywell Zone Valve Motor

## Features

- 【Perfect Replacement】: The 40004850-001 honeywell zone valve motor replaces part No. 40003916-012 power head for honeywell's V8043G zone valves and 40003916-021 power head for Honeywell's V8043A zone valves (simply not connecting red switch wires to anything or cut them off). NOTE: Cannot be used to replace power-heads on honeywell 3-way valves V8044E and V8044A. This V8043E zone valve replacement head includes 802360JA motor and valve assembly. You can watch videos on youtube to install it, which can take you up to 30 minutes. You no longer need to find a plumber, saving you time and money.（This item contains installation screws and detailed installation instructions.）
- 【Compatibility】: The V8043e1012 zone valve honeywell fit for honeywell zone valves V8043E series V8043E1061 V8043E1079 V8043E1020, V8043G (4 wires, with end switch, exact match) and V8043A (2 wires, without end switch & 4 wires, with end switch, exact match). NOTE: if there are FOUR screws securing the power head, you have a very old valve, and the installation is a bit more complicated and requires a conversion kit(No. 40003918). To confirm newer style valve: Just remove the cover and look inside your current power head. With the manual switch on the top, verify there are only screws on the bottom plate on the upper left and lower right corners, but NOT on the other two corners.
- 【High-Quality】:The 40004850-001 replacement head is manufactured by a professional zone valve motor manufacturer and meets and exceeds OEM standards. In addition, our V8043E1012 zone valve replacement head is made of high-temperature and corrosion-resistant metal material, which has undergone precision processing and multiple working tests before leaving the factory in conjunction with the boiler, circulation pump, and thermostat, ensuring efficient and long-lasting operation of the motor, perfect gear engagement without slipping, and stable opening and closing of the valve. Therefore, it has a lifespan of up to 15 years, which can keep your house warm for a long time.
- 【Automatic Opener】: Manual opener is use to operate valves in the event of a power failure. The 40004850-001 zone valve returns to the automatic position when the power is restored.(Note: Auxiliary switch is not energized when the valve is manually opened.) The V8043e1012 zone valve honeywell solves the problems of heating system, allows the continuous operation of water, prevents the failure of your working valve again in cold nights, and provides you and your family with unlimited hot water.
- 【10 Years Free Replacement】: We’re very confident in the quality and service life of the replacement for V8043e1012 honeywell zone valve motor and always provide a 10 year free replacement. For any reason you are not satisfied, you can unconditionally request a free replacement（You don't need to return the old one). If you have any questions, you can contact us at any time.
