3/4" Sweat Connection Zone Valve, normally closed, w/ screw terminal block connection, 3.5 Cv (24v)

Two-way on-off low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water.

Note: Use this valve in closed loop hydronic systems that do not contain dissolved oxygen in system water, such as fresh water from frequent source of makeup water.

Features

• 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" push button 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.
