V4043 and V4044 Motorized Valves

FEATURESThese valves consist of an actuator motor and valve assembly for controlling the flow of hot or cold water.

• The V4043 provides 2-position, straight through control of supply water.

• The V4044 provides 2-position, diverting control of supply water.

• Compact construction for easy installation.• Manual opener for valve operation on power failure. Valve

returns to automatic position when power is restored.• Motor actuator may be replaced without removing the valve

body or draining the system.• Complete powerhead may be removed without breaking

the line connections.• Sweat fit models may be installed without disassembling

the valve.• Fits under the cover of most baseboards.

SPECIFICATIONSModels:V4043 - line voltage, straight-through valves.V4044 - line voltage, 2-position diverting valves.

INSTALLATION

CAUTION1. Installer must be a trained, experienced service

technician.2. Disconnect power supply before connecting wir-

ing to prevent electrical shock and equipment damage.

3. Normally it is not necessary to remove the power-head 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 powerhead will result in damage to the gear train.

4. Always conduct a thorough checkout when instal-lation is complete.

Fig. 8. Mounting Positions.

MOUNTINGThe valve may be mounted in any position on a vertical line. If 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.

Mount the valve directly into the tube or pipe. Make sure that flow through the valve is in the direction indicated by the arrow stamped on the valve body.

On diverting valves, the 3 fittings or ports are labeled on the bottom of the valve body casting. In many applications, port A is connected to the coil unit and is closed when the valve is de-energized. Port B is connected to the coil bypass and is open when the valve is de-energized. Port AB is the inlet and is open at all times. Refer to equipment manufacturer’s instructions for proper fitting of diverting valves.

FLARE FITTING MODELSUse new, properly reamed pipe, that is free from chips. The valve body is threaded for standard 1/2 in. OD copper, 45 degrees SAE flare fitting nuts. These nuts are not furnished with the valve and must be obtained separately.

SWEAT COPPER MODELS1. Use new, properly reamed pipe, that is free from dents

or corrosion.2. Place valve onto pipe. Set the manual opener lever to

MAN. OPEN before applying heat. This will protect the plug inside the valve by removing it from the heat.

3. IMPORTANT: Take care not to burn plastic portion of composite adapter plate when soldering.

4. Sweat joints, but keep the outer surface free from sol-der. DO NOT use silver solder because of the high melt-ing temperatures it requires.

TO INSTALL REPLACEMENT HEADREMOVING REMOVABLE HEAD FROM REMOVABLE HEAD VALVE BODY ASSEMBLY

NOTE: It is not necessary to drain the system if the remov-able head valve body assembly remains in the pipe-line.

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

2. Place the manual operating lever in the MAN. OPEN position. See Fig. 9A.

3. Remove cover. See Fig. 9. Remove the two screws that secure the head to the valve body assembly. (Fig. 9B.)

Fig. 9. Removing Cover.

INSTALLING REMOVABLE HEAD ON REMOVABLE HEAD VALVE BODY ASSEMBLY

1. Place manual operating lever on the replacement head in the MAN. OPEN position and fit the head onto the valve body, ensuring that the shaft seats correctly. See Fig. 10.

2. Secure the head to the valve body with the two screws provided.

3. Remake wiring connections.

Inspect the head installation and the valve body to ensure that all connections and adjustments have been correctly made. Adjust the thermostat or controller connected to the valve so that the valve runs through its cycle. Make sure the valve runs smoothly and positively from closed to open to closed again.

Fig. 10. Installing Replacement Head.

WIRINGAll wiring must agree with local codes and ordinances.

CAUTIONEnsure that all wires are properly dressed and secured before replacing cover to avoid damage to the insulation.

Fig. 11. Typical Wiring for V4043A, V4044A.

OPERATIONAUTOMATIC OPERATIONOn a call for heat by the zone thermostat, the valve opens. When the call for heat ends, the valve closes by integral spring return.

MANUAL OPERATIONThe motorized valve can be opened manually by lifting the manual opener 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 will return to automatic position when the valve is energized.

CHECKOUT1. Raise the setpoint on the zone thermostat above 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 circu-lator or other valve at the end of the opening stroke.

3. Lower the setpoint on the zone thermostat below room temperature.

4. Observe the control devices. The valve should close and the auxiliary equipment should stop.

SERVICEThis valve should be serviced by a trained, experienced service technician.

1. If the valve is leaking, check to see if the O-rings need to be replaced.

2. If the gear train is damaged or the motor is burned out, it is necessary to replace the entire powerhead assembly. See INSTALLATION Section.

NOTE: Honeywell zone valves are designed and tested for silent operation in properly designed and installed systems. However, water noises may occur as a result of excessive water velocity or piping noises may occur in high temperature (over 212° F [100° C]) systems with insufficient water pressure.

NOTE: These hydronic valves are not suitable for use in open loop systems where there is air exposure.
