V4043, V4044 Valves;
V8043, V8044 Zone Valves
APPLICATION
These valves consist of an actuator motor and valve
assembly for controlling the flow of hot and/or cold water.
The V4043 and V8043 provide two-position, straight-
through control of supply water. The V4044 and V8044
provide two-position, diverting control of supply water.
The valves are designed for use with fan coil and other
units requiring quiet, compact water valves. The V8043E
and F also control supply water for baseboard radiators
and convectors. The V4043E and V8043J provide
straight-through control of steam only. Models are
available with 125 or 300 psi operating pressure.
INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
1. Disconnect power supply before connecting
wiring to prevent electrical shock of equip-
ment damage.
2. Normally it is not necessary to remove the
powerhead from the valve body during instal-
lation. 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 powerhead will result in damage to the
gear train.
3. On 24V systems, never jumper the valve coil
terminals even temporarily. This may burn
out the heat anticipator in the thermostat.
IMPORTANT
Use this valve in hydronic heating 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
makeup water, causes the rubber plug inside
the valve to deteriorate and eventually fail.
LOCATION
Install the valve in an area with adequate clearance to:
— Move the manual opening lever on the side of the
powerhead.
— Remove the powerhead cover.
— Wire the powerhead.
— Replace the powerhead motor.
MOUNTING
The valve can be mounted in any position on a vertical
line. If the valve is mounted horizontally; the powerhead
must be even with or above the center line of the piping.
Make sure that enough room is provided above the
powerhead to remove the cover for servicing.
