V8043 Series 5000 QuickFit® Zone Valves
Two-way on-off low voltage valves consist of an actuator and valve
assembly for controlling the flow of hot water.
• All models may be installed without disassembling the valve.
• Compact construction for easy installation.
• Manual opener (on all models, except straight-through, normally
open valves) for valve operation on power failure; valve returns to
automatic position when power is restored.
• Complete powerhead may be removed or replaced without breaking
plumbing line connections or draining the system.
• "Quick Fit" pushbutton powerhead makes it easy to remove for
service.
• Series 5000 replacement powerhead is backward compatible with
series 1000 zone valves.
• Innovative motor technology offers silent operation, water hammer
resist and longer life.
