GENERAL
These small linear valves are used in combination with small
electric linear valve actuators and thermoelectric actuators
for the control of hot and/or chilled water for fan coil units and
small reheaters/recoolers in electric/electronic temperature
control systems.
SPECIFICATIONS
ModelsTwo-way V5832A
Three-way V5833A
Three-way with bypass V5833C
OperationTwo-way stem up to open,
port A to B; Three-way stem up
to close, port A to AB
A built-in return spring in the two-way valve produces an
opening force. In the three-way valve and the three-way valve
with bypass, the spring produces a closing force on the A to
AB ports.
The valves are supplied with a screwed-on adjustment cap
for manual operation and for protection of the stem. This
allows the stem to be set up for filling or initial heating/cooling
during the building construction phase without the use of a
controller or actuator.
The small electric valve actuators as well as the
thermoelectric actuators provide automatic control over the
opening and closing movement of the valve stem.
TYPICAL OPERATION
All types of valves should be mounted in the return flow. If the
∆p-values exceed 60 kPa, attention should be paid to the
development of noise.

Three-Way Valves with Bypass
These valves simplify the installation, which is depending on
the layout of the pipework, as the bypass pipe is part of the
valve. The information for the normal three-way valves is also
valid for this type.

MOUNTING
When installing the valve care must be taken that the flow
direction is correct (see section "Typical Operation"). The
valve must not be mounted with the stem pointing downward.
The adjustment cap must be removed from the valve only
when the actuator is fitted. The valve should be installed as
stress-free as possible with a tightening torque of 25 to
30 Nm.
The valve is supplied complete with mounting instructions.
The water quality must meet VDI 2035 requirements.
ACCESSORIES
Valves V5832A need two connection sets, valves V5833A three connection sets, and valves V5833C four connection sets.

SPARE PARTS
Valve inserts are provided as spare parts for the V5832A and V5833A,C small linear valves. When the tool WV 108 is used,
the valve inserts can be changed without draining the system.
