Application area:

The 3-port motor-driven valve VA32 is used in solar and

heating systems, in which smaller parts of the systems can

be controlled separately or single equipment can be swit-

ched on or off. The valve is equipped with an emergency

manual control, an integrated relay which can be controlled

via an on-off control signal or directly via a potential-free

changeover contact.

Characteristics:

Compact size and modern design, insulated actuator housing.

Easy manual operation for initial installation or emergency

operation. Universal electrical connection by integrated

relay. The signal output of the limit switch in valve position

can be used for control purposes (max. 1 A). The actuator

can be quickly replaced without having to dismount the

unit. No ﬂow reduction, full passage, corresponding to the

versions DN20-DN32.

1. Installation advice

The installation of the valve must be carried out correspon-

ding to the approved technical regulations. Rests of sealing

material and rests of hemp must not get into the valve body.

In order to avoid blocking of the valve ball, the following

advice has to be considered and all solder, brazing or welding

processes near the valve are to be avoided.

Important advice

In order to attain the maximum operating safety and relia-

bility, it is recommended to ﬂush the system and to insert

an appropriate strainer (0,65 µm) in front of each valve (see

installation scheme).

3. Change of ﬂow direction

Change of ﬂow direction A<>AB to AB<>B when the relay

is in rest position.

• Unscrew green housing cover.

• Unscrew sink screw and remove the actuator. Set the ro-

tary slide to the desired basic position (displace the lens

head screws by 90 °).

• Attach the actuator (until it locks) and tighten screw after

the mounting has been ﬁnished. Fasten the cover with the

screws. Functional control.

2. Installation position

The valve can be mounted in any position, but not with the

actuator to the bottom. In order to use the hand operation

+/- 90 °, a cable loop of approx. 25 cm has to be arranged

during the electrical connection. In order to have enough

space to carry out maintenance work, a distance of at least

100 mm from the wall or the device respectively has to be

kept.

Black: if the auxiliary phase L (240 V) is energised, the way

AB<>B opens. If there is no control signal, the valve is

brought back to the initial position AB <> A

Brown: permanent phase L (240 V)

Attention!

Fuse the operating voltage with external pre-fuse max. 2 A.

Red limit switch lead is bared and carries voltage when the

valve is in the open position.
