Honeywell V4044C Manuale operativo

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

PRODUCT DATA

V4044C, V4044F

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
