4Description
TAV 50 is a valve for automatic opening and closing of
a vacuum outlet linked to a central vacuum system. It
comes in six different models, see FigureModels. The
valves are normally automatic, they open and close
governed by a control device.
Figure3 shows TAV 50 in the open position. Com-
pressed air turns the blade when an air signal is ap-
plied to the connection nipple. Figure4 shows the
closed position. The return spring turns the blade back
to this position as soon as the air signal is removed.
The nylon sealing rings supported by the backup rings
seal off against the blade in the open and closed posi-
tions. The backup rings are made of neoprene but are
also available in Viton for extremely difficult applica-
tions.
The control device can be a solenoid valve for electric
control or a flow sensing valve sensing the flow to a
compressed air tool. TAV 50 PC (basic version) is not
fitted with its own control device but an external 3-
port valve is available as an option, see FigureModels,
Figure8, Figure9 and ,Figure10. All versions are com-
pressed air powered except for TAV 50 MA, it requires
no compressed air but is equipped with a lever for the
operation of the valve.
TAV 50 can be fitted with a micro switch to control
the vacuum unit, see Chapter9Accessories. The flow
sensing valve (FV) is described in Chapter8Flow
Sensing Valve.
NOTE!
The current sensing device, item A in Fig-
ureModels, is designed as a control device
for TAV 50. For more information, see

Vacuum Valve TAV 50
EN 4.2ATEX products
All versions of TAV 50 are marked with the CE label.
Depending on the model and purpose of use, some
TAV 50 also have the EX symbol and category mark-
ing. All TAV 50 marked with the EX symbol are cat-
egory 3D equipment according to directive 2014/34/
EU. This means that models with the EX symbol may
be placed in areas classified as zone 22 according to
directive 1999/92/EC.
The manually operated TAV 50 MA is not marked with
the EX symbol as manually operated equipment does
NOT fall under the scope of the directive 2014/34/EU.
Even if the TAV 50 MA does not have the EX marking,
it is highly suitable for use in areas classified as zone
22 and share the same high level of protection as the
TAV 50 with EX marking.
NOTE!
TAV 50 MV-W and TAV 50 MV 24 V AC/DC does
not have the EX marking and may not be in-
stalled in classified areas.
4.3Category limit
The function of the TAV 50 is to be a part of an extrac-
tion 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 a piping system intern-
ally classified as zone 20 or 21. As there is no intern-
al ignition source inside the TAV 50, it is to be con-
sidered as simple piping and does not fall under the
scope of the directive 2014/34/EU.
4.4Permitted materials
The TAV 50 is only intended to be a part of an ex-
traction system transporting dust with the following
properties: MIE (Minimum Ignition Energy) > 3 mJ and
MIT (Minimum Ignition Temperature) > 205°C. Do not
extract items that may cause ignition or blocking.

Vacuum Valve TAV 50
5Installation
WARNING!Risk of personal injury
Use ear protection and safety goggles.
5.1Pressure drop
For pressure drop calculations, count the open TAV 50
in a straight piece of duct with Ø50 mm and a length of
300 mm.
5.2Mounting
For wall mounting, positioning as per Figure5a is
recommended. Flow direction is normally upwards
but the reverse direction is also possible. Mounting
shown in Figure5b is also possible but positioning
“upside-down” (Figure5c) should be avoided. Sup-
plied support brackets should always be used for wall
mounting, see arrows in Figure5d.
NOTE!
The compressed air pipe should be blown clean
before connecting the valve. See Figure6. New
pipes always contain dirt that can cause mal-
function.
CAUTION!Risk of equipment damage
The valve must not bare the load of connection
pipes or other connections which may cause
defects on the valve. Make sure the connec-
tions are firmly installed against the wall, ceil-
ing, floor or suchlike. Hose connections must
be strain relieved.
Mounting in a type SA swing arm is made as shown
in Figure5e using threaded holes in the swing arm
bracket. The support brackets should not be used in
this case.
A compressed air filter should be installed if air qual-
ity is poor. A lubricator is not necessary but may be in-
stalled in front of the TAV 50 FV if the air tool linked to
it requires oiling.
5.3Electrical installation
To ensure proper function and required level of pro-
tection with regards to the equipment category, make
sure that the following points are checked:
• The electrical installation and connection of the
magnetic valve must be done by a certified electri-
cian. A certified electrician must also pay attention
to the conditions for installations in zones classified
according to ATEX.
• Check that proper measures have been taken to
avoid all types of electrical stray currents to and/
or from the piping system and electrical wiring.
Note that the TAV 50 housing is made of conductive
plastic material and must be properly grounded.
• Connected hoses or piping must be conductive and
grounded to the TAV 50 studs (see Figure7a–d).
• Check that the correct voltage is connected to the
solenoid of the magnetic valve. Check the marking
on the solenoid.
• Electrical options, like micro switches, must be con-
nected to an intrinsic safe circuit (for options in-
stalled in ATEX classified zones).
WARNING!Risk of electric shock, over-
heating or possible fire
All wiring must be connected at the correct
connection points (Phase, Neutral and Ground).
Do not connect mains (phase) to the solenoid
ground.
5.4Connections
WARNING!Risk of personal injury
Maximum recommended air pressure is 1 MPa
(10 bars). A pressure regulator must be in-
stalled if the pressure is likely to exceed the
maximum pressure. Recommended work-
ing pressure is 0.6–0.7 MPa (6–7 bars). Min.
pressure for a reliable function is 0.5 MPa (5
bars). Compressed air hoses must be approved
for the actual pressure and must be securely
fastened to the valve nipples. Hose clips must
be fitted correctly.
Figure8 to Figure13 explain how to connect TAV
valves having different control devices. A “flash ar-
row” indicates an electric supply. P indicates a com-
pressed air supply.
• TAV 50 PC (Figure8) is not fitted with its own con-
trol device. It is intended for direct control with a re-
mote 3-port pilot valve (option).
• TAV 50 MA (Figure9) is controlled by a hand-oper-
ated lever. It is used when there is no need for auto-
matic controlling.
• TAV 50 MV (Figure10) has a solenoid valve control
device. The solenoid voltage must match the signal
voltage. TAV 50 MV can be directly controlled by a
stationary electric machine. However, extra branch
fuses should be used if the mains fuses are too large
for this function. See rated voltage and power on
the solenoid. TAV 50 MV can also be controlled by a
handheld electric tool. A current sensing relay (op-
tion, see item A in FigureModels) must be installed
in this case.
• TAV 50 MV-W (Figure11) is supplied with a control
device consisting of a 24 V AC solenoid, a control
box and a sensor ring that can detect a welding cur-
rent. Each valve must be supplied with 24 V AC from
a transformer (optional), that can be shared by a
number of valves.
• TAV 50 FV (Figure12) carries a control device in
the form of a flow sensing valve. This option is used
when TAV 50 is to open for compressed airflow, for
example to an air tool.

Vacuum Valve TAV 50
EN • TAV 50 FV/MV (Figure13) features two control
devices, a flow sensing valve, and a solenoid valve. It
can be controlled by an electric signal as well as by a
compressed airflow.
6 Using Vacuum Valve TAV 50
WARNING!Risk of personal injury
• eep fingers clear off the vacuum connec-
tions when the valve is connected to com-
pressed air. The spring that closes the valve
is strong enough to cause discomfort.
• Make sure the system does not transport ma-
terial which can damage the TAV valve.
• If an unexpected object comes into the sys-
tem, shut the compressed air supply to the
valve immediately and remove the object.
7Maintenance
Installation, repair and maintenance work is to be car-
ried out by qualified personnel using only the original
Nederman spare parts. Contact your nearest author-
ized distributor or Nederman for advice on technical
service.
WARNING!Risk of personal injury
• Disconnect voltage prior to service.
• The compressed air supply must be discon-
nected and any remaining pressure in the
valve discharged before commencing any
maintenance work to the valve. A shut-off
valve before each TAV 50 valve is recommen-
ded.
• The compressed air supply to the TAV 50 valve must
be dry and clean (according to standard ISO 8573-1
class 5). Dirt may result in malfunction by clogging
the control device or the air cylinder inlet. Installing
an air filter may be necessary if clogging occurs.
• Make sure the inside of the valve and the connec-
tion pipes are free from deposits. A build-up of de-
posits inside the piping system may cause a dis-
charge of static electricity.
• Make sure the outside of the TAV valve, and particu-
larly the solenoid, are free from dust layers.
• Oily and sticky substances can sometimes stick to
the valve blade resulting in jamming so that the
valve does not close completely. The valve must
then be dismantled for cleaning.
• The backup rings of chloroprene are resistant to
most substances in reasonable quantities. Oil in a
large quantity can cause swelling to the rings result-
ing in jamming.
• After a million operations, the nylon sealing rings
should be exchanged in order to avoid leakage.
• The piston sealing ring needs changing if internal
leakage occurs in the air cylinder. A small quantity of
a silicon-free pneumatic grease, for example, Microl-
ube GL 261, should be applied to the new ring be-
fore assembly.
• The flow sensing valve (FV) is detailed in
Chapter8Flow Sensing Valve.
To ensure the required level of protection with re-
gards to the equipment category, specifically in ATEX
classified zones, check the following points regu-
larely, at least once a year:
• Inspect the TAV 50 parts described in Figure1 for
damage or malfunction. If the TAV 50 is damaged it
must removed immediately from the classified area,
while it is being repaired or replaced.
• Ensure that no explosive atmosphere and/or dust
layers are present when cleaning, servicing or in-
specting the TAV.
• Ensure that only original (OEM) spare parts are used.
• Ensure that the TAV 50 is not covered with thick
dust layers (>5 mm). This is prevented by setting up
routines for regular cleaning and including these in
the explosion protection document.
8Flow Sensing Valve
The Flow Sensing Valve comes with TAV 50 FV and
TAV 50 FV/MV by delivery.
8.1Technical data
Maximum pressure 1 MPa (10 bar)
Minimum pressure (for
safe operation) 0.5 MPa (5 bar)
Recommended pressure 0.6–0.7 MPa (6–7 bar)
Maximum airflow (flow
valve) 1800 Nl/min
Minimum airflow (flow
valve) 100 Nl/min
8.2Description
The flow sensing valve senses the flow of compressed
air through the valve and gives an air signal at the out-
put nipple. The valve is normally used for controlling
TAV 50 but can also be used whenever an airflow
should control a process. It is fitted with nipples for 13
mm (1/2”) hose. The pressure drop across the valve is
normally small enough to be neglected.
