TAV vent-valve and vent-port
adaptor
Two solenoid-operated vent-valves are available for
system venting. The valves are 24 V dc, normally-
open, and can be driven automatically from the EXC
Controller. The solenoid-valve is fitted in place of
the manual-valve, or alternatively can be fitted with
an adaptor (supplied with the valve) and be used
with any suitable NW10 flanged port on your
vacuum system.
The vent-port adaptor allows the vent-port or the
purge-port to be used with any suitable NW10
fitting: refer to Figure 5.
