APPLICATION

These valves consist of an actuator motor and valve

assembly for controlling the flow of hot or cold water, or

steam.

IMPORTANT

These valves are not for use in systems containing

dissolved oxygen.

FEATURES

• The V4043 and V8043 provide 2-position, straight-

through control of water.

• The V4044 and V8044 provide 2-position diverting

control of water.

• Compact construction for easy installation.

• Manual opener for valve operation on power failure.

Valve returns to automatic position when power is

restored.

• Choice of sweat or flare fitting brass end connections

for standard copper tubing.

• Motor can be replaced by removing one screw,

without disturbing the valve body or draining the

system.

• Complete powerhead may be removed or replaced

without breaking the line connections or draining the

system.

• All models can be installed without disassembling

the valve.

• Fits under the cover of most baseboards.

•Available with integral auxiliary end switch (V4044B;

V8043E,F; V8044E) to permit sequencing of auxiliary

equipment.

• V4043E and V8043J provide straight-through control

of steam.
