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

Function
V4044C and V4044F 2-position hydronic valves are used in
domestic and small commercial applications to control the
flow of hot or cold water. They consist of an actuator and a
valve.
With the manual opener set to AUTO and the actuator
energized, port A of the valve is opened and port B is closed.
When the actuator is de-energized, a spring-return
mechanism drives the ball to close port A, opening port B.
Port A can also be opened with no electrical power by moving
the manual opening lever over the stop and pushing slowly
and firmly to the MAN. OPEN position. The stop permits the
valve to be locked with port A in the open position. The valve
returns to the automatic position when the valve is energized.
A power failure will leave the valve at the spring-returned
position. When power is restored, the valve will respond to
controller demand.

NOTE: The V4044C has no end switch. It is equipped with a 3 wire cable (line, neutral, earth)
The V4044F1034 has an SPST end switch. It is equipped with a 5-wire cable (line, neutral, earth, end switch). The end
switch closes when the valve is in position AB – B
The V4044F1000 has an SPDT end switch. It is equipped with a 6-wire cable (line, neutral, earth, end switch NO, end
switch NC)
The length of all cables is 1m
