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

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

. 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.
. On 24V systems, never jumper the
valve coil terminals even temporarily.
This can burn out the heat anticipator in
the thermostat.

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.
