The Honeywell V8043B1027 Electric Zone Valve is a 24 volt, 3/4-inch sweat connection valve designed for controlling the flow of hot water in heating systems. This electric zone valve features a straight-through valve body and a normally closed position. It is rated to 3.5 Cv, 20 psi close-off pressure, and a maximum operating temperature of 200 degrees Fahrenheit.
The Honeywell V8043B1027 includes an actuator and valve assembly, designed for efficient flow control. The powerhead can be removed and replaced without needing to drain the system, making installation and maintenance straightforward. A manual opener on the actuator switch allows operation during power failures, automatically returning to auto mode once power is restored.
