V4044C, V4044F
Motorized Zone Valves
3-PORT HYDRONIC VALVES
Design
V4044C and V4044F zone valves consist of:
• 3-way valve housing with BSPP internal threads
• Control ball assembly
• Actuator assembly with cable
• V4044F1000 with SPDT end switch
• V4044F1034 with SPST end switch
Materials
• Valve housing made of forged brass
• Spindle shaft made of brass
• O-ring seals made of EPDM rubber
• Ball plug made of NBR rubber
• Actuator cover and base made of zinc-plated steel
Application
Honeywell V4044C and F 3-port hydronic valves are used in
domestic and small commercial heating and cooling
applications to control the flow of hot or cold water.
They are designed for on-off zone control of domestic sys-
tems and can be used to control individual fan coil, radiator,
space heater or convector applications. They can be con-
trolled by a line voltage SPST controller such as a room
thermostat, aquastat or flow switch.
The actuator head is removable without affecting the integrity
of the water system.
Features
• Rugged design
• Control by a line voltage SPST controller
• Actuator head installation does not require draining of
the system
• High flow rate capacity
• Indifferent to dirt in system
