Important Safety Note
Danger
When the upper dead centre is reached during
opening and closing by means of the operating
lever, the latter will instantaneously move
downwards or upwards. Persons who are
standing in close vicinity may be injured.
Closing with the aid of a release cord must
only be performed when nobody is in the
proximity of the operating lever. Do not
undertake any installation and maintenance
work unless the container is completely empty
and degassed. Escaping fumes and gas can
endanger life and health of the person
responsible for installation and maintenance
and cause material damage.
Tank container bottom valves must only be
installed by qualified staff. Consider the
relevant regulations for the prevention of
accidents.
Carefully read through installation instructions
before mounting the valve.
Use GESTRA genuine spare parts only.
Observe the corresponding regulations
established by the tank container operators
when loading or unloading the container.

Function
The manually-operated container bottom valve
with spring-assisted lever ensures clear
indication of “OPEN” and “CLOSED” positions
and operates without the possibility of
intermediate positions.
The container valve type CV 10 is part of a
bottom loading and unloading system for
hazardous tank containers (TC) of IMO classes
1 and 2. It forms the first inner shut-off as
defined by TRTC 026, and is therefore part of
the pressure-containing shell.
Design
Valve range includes angled inlets of 30° and
45° (required to account for the different
geometries of the container bottoms).
The face-to-face dimensions (centre foot flange
to seating surface loading flange) have to
correspond to the varying overall lengths of
containers with different face-to-face
dimensions (min. 127 mm).
Alternatively with or without heating jacket
(required if the product requires heat).

Installation
Fitting (Fig. 1)
1. Insert fixing studs
D
and
E
into valve
mounting flange
F
.
2. Place gasket
C
onto the foot flange of the
CV 10
A
and carefully tighten with fixing
studs. Take care not to damage the PTFE
envelope of the gasket.
3. Secure the CV 10 in position with the aid of
two nuts
B
.
4. Continue to screw in the two nuts until the
first threads of the top fixing stud
D
appear
at the rear of the foot flange. Screw the
corresponding nuts onto the fixing studs.
The restricted spacing to the valve body
makes a retro-fit of the nuts impossible.
5. Tighten all nuts
B
fingertight.
6. Tighten all nuts
B
gradually and in
diagonally opposite pairs by hand using a
spanner.
7. Tighten all nuts
B
gradually and in
diagonally opposite pairs with a torque of
36 + 2 Nm.
Dismantling
1. For the removal of the valve proceed in
reverse order.
