TURBO-V VENT DEVICE DESCRIPTION
The 969-9831 Turbo-V vent device, consisting of a vent
control unit and a vent valve, is a complete unit suitable
for automatic venting of the Turbo-V pump when it is
switched off or during a power failure switch (refer to
the following figure).
The Vent device is powered by the Turbo-V controller
and a battery back-up capability is built in.
The vent control unit is provided with a delay time to
avoid undesired venting during a temporary power
failure and to allow closure of the system valves before
venting. A second setting is also provided to control the
venting time to atmosphere.
The Turbo-V pump must be vented when it is shut
down to prevent the forepump oil from contaminating
the Turbo-V and the connected chamber.
