2.1 Safety precautions
●Observe the safety and accident prevention regulations.
●Check regularly that all safety precautions are being complied with.
●Do not loosen any plug connection during operations.
●Keep leads and cables well away from hot surfaces (> 70 °C).
●Always ensure a safe connection to the protective earthing conductor (PE, protection
class I).
●Before carrying out any work disconnect the unit and all associated installations safely
from the mains.
2.2 Proper use
●The fore vacuum safety valve serves to the installation in a fore-vacuum line between
a turbopump and a backing pump.
●The fore vacuum valve TVV 001 serves to protect a turbopump against unintended
venting via the fore-vacuum line in the case the backing pump stops.
2.3 Improper use
Improper use will cause all claims for liability and warranties to be forfeited. Improper use
is defined as usage for purposes deviating from those mentioned above, especially:
●connection to pumps or units which are not suitable for this purpose according to their
operating instructions

3.2 Function
The fore vacuum safety valve TVV 001 is a direct acting 2/2-way solenoid valve with
manual override and adjustable switch-on delay. The valve is qualified for the fitting into
a fore vacuum line between a turbopump and a backing pump. It protects the turbopump
against unintended venting in case the backing pump stops. The valve is normally closed
and will be energized together with the backing pump.

4.1 Assembly
The valve body is marked on the high vacuum side with an "A", and on the fore-vacuum
side with a "P". The valve is equipped with DN 16 ISO-KF flange connections on both
sides.
Install the valve into the fore-vacuum line according to the "A-P" markings so that the
button for manual actuation points towards the fore-vacuum side.
Place the turbopump vertically if possible, with the valve plug upwards.
4.2 Electrical connection
Fig. 2: Contact diagram and components plan on valve plug for TVV 001
Observe the information on the rating plae.
Unscrew the protection cover from the valve plug.
Make electrical connections on the terminals of the valve plug.
Connect electric power supply together with the mains connection for the backing
pump (e.g. via a Pfeiffer Vacuum relay box).
WARNING
Danger of bursting
Uncontrolled overpressure can lead to destruction of the valve and considerable dam-
age to the pump system.
Follow the installation instructions for the valve.
Observe technical data for the valve.
DANGER
Voltage-bearing elements
Danger to life from electric shock.
The electrical connection can be carried out only by trained and authorised electri-
cians.
Disconnect the power supply and secure it against being switched back on.
Ensure the system is adequately earthed.
