4 Descripon
4.1 Funcon
TAV 50 is a valve for automac opening and closing of a vacuum outlet linked to a central
vacuum system. It comes in six dierent models, see gure page 8. The valves are normally
automac, they open and close governed by a control device.
The control device can be a solenoid valve for electric control or a ow sensing valve sensing
the ow to a compressed air tool. TAV 50 PC (basic version) is not ed with its own control
device but an external 3-port valve is available as an opon (see page 11). All versions are
compressed air powered except for MA which is manually operated.
TAV 50 can be ed with a micro switch to control the vacuum unit (see accessories in
secon 9. Accessories). The ow sensing valve (FV) is described in secon 8. Flow Sensing Valve.
4.2 ATEX products
All versions of TAV 50 are marked with the CE label.
Depending on model and purpose of use, some TAV 50 also have the EX symbol and category
marking.
All TAV 50 marked with the EX symbol are category 3D equipment according to direcve
2014/34/EU. This means that models with the EX symbol may be placed in areas classied as
zone 22 according to direcve 1999/92/EC.

The manually operated TAV50 MA is not marked with the EX symbol as manually operated
equipment does NOT fall under the scope of the direcve 2014/34/EU. Even if the TAV50 MA
does not have the EX marking, it is highly suitable for use in areas classied as zone 22 and share
the same high level of protecon as the TAV50 with EX marking.
Please note that TAV 50 MV-W and TAV 50 MV 24 V AC/DC does not have the EX marking and
may not be installed is classied areas.
4.3 Category limit
The funcon of the TAV 50 is to be a part of an extracon piping system. Even if the TAV 50
with EX symbol is category 3D equipment for use in zone 22 (TAV 50 exterior), it can be used
with piping system internally classied as zone 20 or 21. As there is no internal ignion source
inside the TAV 50, it is to be considered as simple piping and does not fall under the scope of the
direcve 2014/34/EU.
4.4 Permied materials
The TAV50 is only intended to be a part of an extracon system transporng dusts with the
following properes: MIE (Minimum Ignion Energy) > 3 mJ and MIT (Minimum Ignion
Temperature) > 205 °C. Do not extract items that may cause ignion or blocking.

5.1 Funcon
Figure 3 shows TAV 50 in the open posion. Compressed air turns the blade when an air signal is
applied to the connecon nipple. Figure 4 shows the closed posion. The return spring turns the
blade back to this posion as soon as the air signal is removed.
The manual version, TAV 50 MA, requires no compressed air but is equipped with a lever for
operaon of the valve.
The nylon sealing rings supported by the backup rings seal o against the blade in the open
and closed posions. The backup rings are made of neoprene but are also available in viton for
extremely dicult applicaons.
6 Installaon
6.1 Mounng
For wall mounng, posioning as per gure 5a is recommended. Flow direcon is normally
upwards but reverse direcon is also possible. Mounng shown in 5b is also possible but
posioning “up side down” (5c) should be avoided. Supplied support brackets should always be
used for wall mounng, see arrows in gure 5d.
CAUTION! Risk of equipment damage.
The valve must not bare the load of connecon pipes or other connecons which may cause
defects on the valve. Make sure the connecons are rmly installed against the wall, ceiling,
oor or suchlike. Hose connecons must be strain reliefed.
Mounng in a type SA swing arm is made as shown in gure 5e using threaded holes in the
swing arm bracket. The support brackets should not be used in this case.
