The Honeywell V8043E1012 two-way on-off low voltage 3/4-inch 24V motorized zone valve valve consists of an actuator and valve assembly for controlling the flow of hot water.
Features
The Honeywell V8043E1012 includes a manual opener for valve operation on power failure; valve returns to automatic position when power is restored. This valve may be installed without disassembling, and the compact construction allows for easy installation. The complete powerhead may be removed or replaced without breaking plumbing line connections or draining the system and the actuator motor may be replaced without removing the valve body or draining the system.
