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).

Sweat the joints, keeping the outer surface free from solder. DO NOT use silver solder because of the high melting temperature required. 1. Disconnect the power supply before connecting the wiring to prevent electrical shock or equipment damage. 2. Disconnect the leadwires to the powerhead at the terminal block or conduit connection.
