V8043A,E,F 5000 Series
LVES ZONE VA
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.

120V, 4.4A running, 26.4A Inrush (60 Hz); 50 VA Pilot duty at 24 V.
Fluid Temperature:
Standard models (class F motor):
200° F (93° C) Max.
Ambient Temperature:
125°F (52° C) Max.
Humidity Limits:
95% Relative Humidity, Non-condensing
Shipping and Storage Temperature:
-40°F to 150°F (-40°C to 65°C).
Atmosphere:
Non-corrosive, non explosive.
Maximum Soldering Temperature:
500°F (260°C). Rubber ball plug must be moved awayfrom the seat for solder ing.
Maximum System Pressure Rating:
300 psi (2000 kPa), PN20.
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.

product operation as provided in these instructions.
Location
Install the valve in an area with adequate clearance to:
Mov- e the manual opening lever on the side of the actuator
Remov- e 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
Read these1. instructions carefully |
. Failure |
|
to follow them could damage the product |
||
or cause a hazardous condition. |
|
|
Check the2. r |
atings given in the |
|
instructions and on the product to make sure the product is suitable for your application.
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.

MOUNTING
The valve can be mounted in any position rtical lineon a ve . 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 r er fo servicing.
Mount the valve directly in the tube or pipe after the coil. Make sure that the flow through the valve is in the direction
rro indicated by w stamped on the valve body.

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. (See Operation and Checkout Sections.)
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.
Switch1. power supply OFF. Disconnect electrical leads carefully, noting the position and colour of each lead.
Place2. the manual lever in the MAN. OPEN position.
Remove3. actuator by fully depressing spring release button and lift it straight off of the body.
Fig. 2 - Mounting Positions
Sweat Copper Models
1.Use new, properly reamed pipe, free from dents or corrosion.
Place2. the valv e 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 REPLACEMENT ACTUATOR ON THE VALVE BODY
1.Align the parallel flat surfaces in
double-D shaft of valve body with notch in side of body (i.e. 90°to water flow.) See Fig. 4. This makes actuator attachment easier.
2.Wiring connections may be made either before or after actuator installed on valve body.
3.Place the manual lever on the actuator in the MAN. OPEN position.
