highly suitable for use in areas classified as zone 22 and share the same high
level of protection as the TAV 100/150 with EX marking.
Please note that TAV 100/150 MV 24 V AC/DC does not have the EX marking
and may not be installed in classified areas.
Category limit
The function of the TAV 100/150 is to be a part of an extraction piping system.
Even if the TAV 100/150 with EX symbol is category 3D equipment for use in
zone 22 (TAV 100/150 exterior), it can be used with piping system internally
classified as zone 20 or 21.
As there is no internal ignition source inside the TAV 100/150, it is to be
considered as simple piping and does not fall under the scope of the directive
2014/34/EU.
Permitted materials
The TAV 100/150 is only intended to be a part of an extraction system
transporting dusts with the following properties: MIE (Minimum Ignition
Energy) > 3 mJ and MIT (Minimum Ignition Temperature) > 205 ºC. Do not
extract items that may cause ignition or blocking.

Function
The description refers to figure 3. When the valve disc (item 3) is turned
clockwise to its limit, the hole in the disc will be in line with the inlet/outlet
muffs and the valve is thus open. At the anticlockwise limit the valve disc
blocks the bore between the inlet/outlet muffs and the valve is thus closed.
The manual version, TAV 100/150 MA, requires no compressed air but is
equipped with a lever for operation of the valve.
The sealing rings and back-up rings seal against the disc. The back-up rings are
made of chloroprene.
