V8043 Low Voltage Normally Closed Zone Valves
Two-way on-off low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water.
• 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.
• Compact construction for easy installation.
• Complete powerhead may be removed or replaced without breaking plumbing line connections or draining the system.
• Actuator motor may be replaced without removing the valve body or draining the system.
Application: Hydronic Control Typ e: Two position Body Pattern: Two-way, Straight-through Valve Action: Spring return to close Volt ag e: 24 Vac Frequency: 50 Hz; 60 Hz Power Consumption: 7.7 VA De-energized Position: Normally Closed Fluid Temperature Range: 50 F to 200 F (10 C to 93 C) Maximum Ambient Temperature: 125 F (52 C) Comments: 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. Valve designed for cycling (not constantly powered on) applications.
