These valves consist of a motorized
actuator and valve assembly for controlling
the flow of hot water to a heat exchanger
such as a radiator, convector, finned
baseboard radiator, or infloor radiant coil
for space temperature control. The V8043
5000 series valves provide two-position,
straight through control of supply water at
up to 300 psi operating pressure.

CAUTION
3. Installer must be a trained, experienced
service technician.
4. After installation is complete, check out
product operation as provided in these
instructions.
1. Disconnect power supply before
connecting wiring to prevent electrical
shock or equipment damage.
Service Medium:
Suitable for glycol/water mix up to 50:50
use in closed hydronic systems. Not for
use with oxygenated water, potable water
or steam.
Use this valve in hydronic systems which
do not contain dissolved oxygen in the
system water. The dissolved oxygen,
which is found in systems that have a
frequent source of make-up water, causes
the rubber plug inside the valve to
2. Normally it is not necessary to remove
the actuator from the valve body during
installation. If the valve must be
disassembled, be certain that it is
reassembled with the water flow in the
direction of the arrow. Reversal of the
actuator results in damage to the gear
train.
3. On 24V systems, never jumper the
valve coil terminals even temporarily.
This can burn out the heat anticipator in
the thermostat.
Location
Install the valve in an area with adequate
clearance to:
- Move the manual opening lever on the
side of the actuator
- Remove the actuator cover
- Wire the actuator
- Replace the actuator motor

MODELS
1. Read these instructions carefully. Failure
to follow them could damage the product
or cause a hazardous condition.
2. Check the ratings given in the
instructions and on the product to make
sure the product is suitable for your
application.
The V8043 normally closed valves can be
opened manually by moving the manual lever
slowly and firmly to the MAN. OPEN position

Automatic Operation
Fig. 28 - V8043 operation for normally closed valve.
On a call for heat by the zone thermostat,
the valve opens and its auxiliary switch
contacts make, closing the circuit to the
system circulator. In a multizone system with
all the valve auxiliary switches wired in
parallel, any zone calling for heat can operate
the circulator. When the call for heat ends, the
valve closes by integral spring return. The
auxiliary switch contacts break the circulator
circuit.
CHECKOUT
1. Raise the setpoint on the zone
thermostat above the room
temperature to initiate a call for heat.
2. Observe all control devices—the valve
should open and the auxiliary switch
should make the circuit to the
circulator or other valve at the end of
the opening stroke.
3. Lower the setpoint on the zone
thermostat to below the room
temperature.
Manual Operation
The motorized valve can be opened
manually by lifting 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 in the open position.
The valve returns to automatic position when
the valve is energized.
4. Observe the control devices. The valve
should close and the auxiliary
equipment should stop.
SERVICE
Normally Closed Models
This valve should be serviced by a trained,
experienced service technician.
1. If the valve is leaking, drain the system
and check to see if the O-ring needs
replacing.
With the manual opener set to AUTO and
the actuator energized, the valve is opened
as shown in Fig. 28A. When the actuator is
de-energized, a spring-return mechanism
drives the valve to the closed position as
shown in Fig. 28B. The valve 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 in the open position.
2. If the gear train is damaged, replace
the entire actuator assembly. See the
Installation section. If the motor is
burned out, replace the motor. See
Replacement Parts list in the
TRADELINE® Catalog.
NOTE: Honeywell zone valves are designed
and tested for silent operation in
properly designed and installed
systems; however, water noises can
occur as a result of excessive water
velocity or piping noises can occur in
high temperature (higher than 212°F
(100°C) systems with insufficient water
pressure. Valves are designed for
normal cycling operations. Product life
will be shortened if energized
The valve returns to the automatic position
when the valve is energized.
Auxiliary switch is not energized when
the valve is manually opened.
NOTE: Flow direction arrow is stamped on
the valve body indicating flow
direction from Inlet Port A to Outlet
Port B.
