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.

The valve location should be in an area where the 
temperature does not exceed the maximum valve 
operating temperature as shown in Fig. 1. The maximum 
valve operating temperature depends on the maximum 
ambient temperature at the valve location and the 
maximum fluid temperature. Using the graph in Fig. 1, 
the maximum valve operating temperature can be found 
as follows:

1.

Measure ambient temperature at valve and locate 
this temperature on the ambient temperature scale 
on the graph.

2.

Draw a line from this ambient temperature, parallel 
with the fluid temperature scale, to the maximum 
fluid temperature line.

3.

Draw a line from this point down to the fluid temp-
erature scale to find maximum operating tempera-
ture. (Note the example, shown by the dashed line 
in Fig. 1).
