V8043A, E, F

5000 Series Zone Valves

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.

SPECIFICATION

Actuator Electrical Rating:

24 Vac 60 Hz, 0.30 A Current Draw;

5 W, 7.2 VA maximum

Electrical Connection: 18” leads or screw terminal board.

Auxiliary Switch Rating:

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).

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 away

from the seat for soldering.

Maximum System Pressure Rating: 300 psi (2000 kPa),

PN20.

Flow Characteristics:

Quick opening for on-off application.

Slow return for water hammer resist.

Maximum Close-off Rating (@ Flow Capacity Rating):

20 psi (@ 3.5 Cv).

8 psi (@ 8 Cv).

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.

MODELS
