Motorized Zone Valves
V4043 Line Voltage Zone Valves for Steam
Flare Connection Sweat Connection
Two way on-off line voltage valves consist of an actuator motor and
valve assembly for controlling the flow of low pressure steam.
• 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.
• All models may be installed without disassembling the valve.
• Compact construction for easy installation.
• Complete powerhead may be removed or replaced without breaking
plumbing line connections or draining the system.
• Motor may be replaced without removing the valve body or draining
the system.
• Suitable for heating applications.
