Description:
Hydronic Zone Valve, Tube Size 1 Inch, Coefficient of Volume 3.5, Electrical Connections 18 Inches Leads, 24 Volts, Motorized, Maximum Pressure 125 PSI
V8043; V8044 Low Voltage Zone Valves
ON-OFF and diverting low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water, and some models for 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 line connections or draining the system.
Actuator motor may be replaced without removing the valve body or draining the system.
Chilled water models available for cooling and heating applications.
