TV 141 NAVIGATOR VENT VALVE KIT INSTALLATION PROCEDURE
OVERVIEW
The "TV 141 Navigator Vent Valve" kit, consisting of a
control unit and valve, is a complete unit for automatic
pump venting when the pump is switched off or during
a power failure. The valve is normally open during
power off conditions, is electromechanically activated
and secured (Viton-sealed) by means of an M8 thread
with related O-ring on the high vacuum port. The air
input into the valve is filtered by means of a specific
filter located on the valve's own air inlet.
The control unit is powered by the Turbo-V controller
which is not suitable for rack mounting.
The control unit is activated with a preset delay of
approximately 0.8 seconds to avoid undesired venting
during a temporary power failure and to allow the
closure of the system valves before venting.
