TAV vent-valve
B580-65-880 Issue G
4 TAV vent-valve
4.1 Description
To maintain cleanliness of your vacuum system, we recommend that you vent the pump or vacuum system whenever
you switch the pump off.
The TAV vent-valves are 24 V d.c., electrical-solenoid operated valves which you can use to vent your vacuum system
with atmospheric air or dry nitrogen when you switch the EXT pump off.
The TAV vent-valve is normally open when the solenoid is de-energised; this is the configuration that you need to use
an EXC Controller, a TIC or an EXT DX podule to control the vent-valve.
Refer to Figure 23. The TAV vent-valve is supplied with a sintered bronze inlet-filter (1), a riffled hose connector (7)
and 3 metres of cable.
You can connect your dry nitrogen supply to the hose connector.
An NW10 adaptor (3) is also supplied to convert the 1/8 inch BSP outlet connector (Figure 22, item 2) of the TAV
vent-valve for direct connection to your vacuum system.
The TAV vent-valve can be powered and controlled from an EXC Controller, a TIC, an EXT DX podule, or from any
suitable electrical supply.
