Honeywell V8043, V8043A, V8043E, V8043F User Manual

V8043A,E,F 5000 Series

APPLICATION

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.

Quick Fit actuator provides easy snap on and off connection to the valve assembly.

ZONE V ALVES

Patent Pending

Actuator Materials:

Case:galvanized steel. Cover : zinc plated steel. Sector gear: Brass

Valve Material:

Body of forged brass; drive shaft stem of stainless steel; ball plug of Buna-N rubber; o-ring seals of EPDM rubber.

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 deteriorate and eventually fail.

Approvals:

CSA C/US Certified to Canadian Standards Association and Underwriter's Laboratories Standards.

CAUTION

1. Disconnect power supply before connecting wiring to prevent electrical shock or equipment damage.

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 tempor arily. This can burn out the heat anticipator in the thermostat.

INSTALLATION

When Installing this Product…

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.

3. Installer must be a trained, experienced service technician.

4. After installation is complete, check out product operation as provided in these instructions.

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

The valve location should be in an area where the temperature does not exceed the maximum valve operating ambient temperature and fluid temperatuare.

Manual Lever

The V8043 normally closed valves can be opened manually by moving the manual lever slowly and firmly to the MAN. OPEN position and pushing up to the stop. The stop permits the valve to be locked in the open position. The valve returns to automatic position when it is energized.

The valve can be mounted in any position on a vertical line. See Fig. 2. If the valve is mounted horizontally; the actuator must be even with or above the center line of the piping. Make sure to leave enough room above the actuator to remove the cover for servicing.

Mount the valve directly in the tube or pipe after the coil.

TO REMOVE THE ACTUATOR FROM THE VALVE BODY (See Fig. 3)

NOTE!

It is not necessary to drain the hydronic system if the valve body assembly remains in the pipe line.

1. Switch power supply OFF. Disconnect electrical leads carefully, noting the position and colour of each lead.

2. Place the manual lever in the MAN. OPEN position.

3. Remove actuator by fully depressing spring release button and lift it straight off of the body .

4. Line up motor coupling to the parallel flat surfaces in double-D shaft of body and fit the actuator onto the valve body, ensuring that the shaft seats correctly . (See Fig. 5)

5. Snap actuator onto body by pressing down.

6.The manual lever may be released manually, but it is also automatically released when the valve is operated

1. Use new, properly reamed pipe, free from dents or corrosion.

2. Place the valve on the pipe. Set the manual opening lever to MAN. OPEN position before applying heat. This protects the plug inside the valve by removing it from the seat.

3. Sweat the joints, keeping the outer surface free from solder. DO NOT use silver solder because of the high melting temperature required.

TO INSTALL A COMPLETE V ALVE (V8043):

1. Disconnect power supply before connecting wiring to prevent electrical shock or equipment damage.

2. Install valve into pipe on the return side of the coil. (See Mounting Section.)

3. Make wiring connections to valve. (Refer to Wiring section for proper instructions.)

4. Inspect the valve installation to ensure that all connections and adjustments have been correctly made. Adjust the

WIRING

Disconnect the power supply before connecting wiring to prevent electrical shock or equipment damage. All wiring must comply with local codes and ordinances. Connections to the individual valves are shown in Fig. 6 and 7. See Fig. 8 through 14 for typical hookups. If replacing a Taco, Dole, Flair or White Rodgers 3-wire valve with a 2-wire V8043E or F, see Fig. 15 through 27. Check that the pressure rating of the new valve is appropriate for the application.
