3 Product description
1510014218/00 EN
This chapter contains an overview of the design and function of the product.
3.1 Scope of delivery
The product is delivered as follows:
▪ Shutter valve
▪ O-ring gasket for tank-side mounting flange
▪ Bypass for resetting (available as an option)
3.2 Function description
The device is a protective device that, in the event of a steady loss of fluid
from the tank, stops the flow of fluid from the conservator to the tank, reduc-
ing the risk of fire and environmental pollution.
The device works automatically. If the flow rate from the conservator to the
tank exceeds a factory-set value, the device closes the pipe leading to the
tank.
If the device trips, a signal is sent via up to 2 reed-type switches (normally
open contact or change-over contact). The reed-type switches are con-
nected to the electrical controller and the monitoring circuit of the trans-
former.
Transformer operating phases
The conditions described in the following can arise during normal trans-
former operation and will not normally lead to the device closing the pipe:
▪ During the heating phase when the oil temperature increases, oil flows
from the tank to the conservator due to the expansion of the oil volume.
The flow rate is normally ≤30dm3/min.
▪ During the cooling phase when the oil temperature decreases, oil flows
from the conservator to the tank due to the contraction of the oil volume.
The flow rate is normally ≤30dm3/min.
Transformer error states
The device closes automatically if the following condition arises:
▪ If a tank leak arises, for example when a bushing fails or a pressure relief
device springs open and then does not close again correctly, oil flows
back from the conservator to the tank. The expected flow rate is normally
>>30dm3/min.

3 Product description
16 10014218/00 EN
The flow of oil from the conservator to the tank must be stopped to prevent a
critical loss of oil. This abnormal state is signaled via reed-type switches.
3.2.1 Main valve function
During the normal transformer heating and cooling phases, the main valve is
held open by the float pushing upward without the oil flow in the pipe be-
tween the tank and conservator slowing down.
The main valve only closes in the event of a hydraulic pressure loss that is
greater than the upward force of the float.
The oil flowing through the device is associated with a hy-
draulic pressure loss that depends on the following:
- Oil viscosity
- Oil flow rate depending on the cooling conditions
- Oil flow rate that depends on briefly occurring events such as
the startup of pumps, the elasticity of the tank or of the cooler,
etc.
In the event of an error that causes a flow rate of >>30dm3/min, the main
valve closes and an electrical signal is sent via the reed switch.
3.3 Design
The device is suitable for installation in the nominal DN50, DN80 or DN100
pipe diameters.
The connecting flanges on the device can have 4 or 8 drill holes (see "Draw-
ings" chapter for available versions).

3 Product description
1710014218/00 EN
The device can be equipped with a maximum of two reed-type switches
(normally open contact or change-over contact). The reed-type switches are
connected electrically via the terminal box.

4 Packaging, transport and storage
1910014218/00 EN
4.1 Purpose
The packaging is designed to protect the packaged product during transport,
loading, unloading and during periods of storage in such a way that no detri-
mental changes occur. The packaging must protect the goods against per-
mitted transport stresses such as vibration and knocks.
The packaging also prevents the packaged goods from moving impermissi-
bly within the packaging.
4.2 Suitability, structure and production
The goods are packaged in a sturdy cardboard box. This ensures that the
shipment is held securely in the intended transport position.
Inlays inside the box stabilize the goods, preventing impermissible changes
of position, and protect them from vibration.
4.3 Markings
The packaging bears a signature with instructions for safe transport and cor-
rect storage. The following symbols apply to the shipment of non-hazardous
goods. Adherence to these symbols is mandatory.
Protect against moisture Top Fragile
Table4: Shipping pictograms
4.4 Transportation, receipt and handling of shipments
In addition to vibrations, jolts must also be expected during transportation. In
order to prevent possible damage, avoid dropping, tipping, knocking over
and colliding with the product.
If the packaging tips over or falls, damage is to be expected regardless of
the weight.

4 Packaging, transport and storage
20 10014218/00 EN
Every delivered shipment must be checked for the following by the recipient
before acceptance (acknowledgment of receipt):
▪ Completeness based on the delivery slip
▪ External damage of any type.
The checks must take place after unloading when the cartons or transport
container can be accessed from all sides.
Visible damage
If external transport damage is found upon receipt of the shipment, proceed
as follows:
▪ Immediately record the transport damage found in the shipping docu-
ments and have this countersigned by the carrier.
▪ In the event of severe damage, total loss or high damage costs, immedi-
ately notify CEDASPE S.r.l and the relevant insurance company.
▪ After identifying damage, do not modify the condition of the shipment fur-
ther and retain the packaging material until an inspection decision has
been made by the transport company or the insurance company.
▪ Record the details of the damage immediately on site together with the
carrier involved. This is essential for any claim for damages.
▪ If possible, photograph damage to packaging and packaged goods. This
also applies to signs of corrosion on the packaged goods due to moisture
inside the packaging (rain, snow, condensation).
▪ Be absolutely sure to also check the sealed packaging.
Hidden damage
When damage is not determined until unpacking after receipt of the ship-
ment (hidden damage), proceed as follows:
▪ Make the party responsible for the damage liable as soon as possible by
telephone and in writing, and prepare a damage report.
▪ Observe the time periods applicable to such actions in the respective
country. Inquire about these in good time.
With hidden damage, it is very hard to make the transportation company (or
other responsible party) liable. Any insurance claims for such damage can
only be successful if relevant provisions are expressly included in the insur-
ance terms and conditions.
