General features of Coster Bag-On-Valve filling machines
Coster Tecnologie Special i , founded in the
early 60’s, serves as a global partner in
the aerosol sector, offer ing aerosol com-
ponents and machines for f i l l ing aerosol,
spray and dispensing products.
Leveraging over 40 years experience and
know-how of both i ts valve and machinery
divisions, Coster is a world leader in the
provision of innovative services and high
qual i ty products designed to meet custom-
ers’ needs.
To sat isfy the increasing demand for Bag-
On-Valve f i l l ing, Coster has developed a
series of machines to al low for a secure
processing of dual compartment systems,
ranging from semi-automatic ( for labora-
tory and small-scale production) to ful ly
automatic machines, suitable for both l iq-
uid and compressed gas (Nitrogen, Air) .
The range of Coster BOV f i l l ing machines
is complemented by a series of anci l lary
machines such as mixing units for the pre-
parat ion of post-foaming gel, which al low
Coster to offer complete support to cus-
tomers for al l BOV f i l l ing requirements.
Coster BOV f i l l ing machines are currently
used to f i l l shaving gels, pharmaceutical
products, cosmetics and food.
BOV filling machine with a production speed up to 50 CPM for a customized product. The machine carries out the following operations: undercup pressurisation and internal crimping, external crimping, through the valve pressurisation with LPG, vacuum purging, product filling in the bag, check of filling pressure.

Coster Bag-On-Valve filling machines are suitable both for liquid and compressed gas
The key feature of BOVs is the fact that
they keep the product separate from the
propel lant: the propel lant, l iquefied or
compressed gas, is contained inside the
can outside the bag and the product is
contained inside the bag. Coster BOV f i l l-
ing machines al low f i l l ing of a wide range
of products and both types of propel lants.
As shown in the pictures below, the fil l ing
cycle begins with the insertion of the BOV
into the can and proceeds in slightly differ-
ent ways depending on the propellant used.
For l iquefied gas, the f i l l ing cycle goes on
with valve crimping, through the valve pres -
surisat ion with l iquefied gas, vacuum purg-
ing and through the valve product f i l l ing.
For compressed gas, the cycle goes on
with undercup pressurisat ion with com-
pressed gas and valve crimping, vacuum
purging and through the valve product f i l l-
ing. I t is advisable to use a pressure check
stat ion after undercup pressurisat ion in
order to check the f i l l ing pressure of com-
pressed gas.
The f i l l ing cycle of Bag-On-Valves then
proceeds as in the standard aerosol cycle
(check weight, water bath, actuator and
overcap f i t t ing).

BOV filling cycle
As seen in the previous pages, the BOV f i l l ing cycle begins with BOV insert ion and
proceeds in sl ight ly dif ferent ways depending on the propel lant used.
Above: automatic indexing unit with a production speed up to 40 cans per minute for filling the BOV with post-foaming shaving gel, with liquefied and/or compressed propellant. The unit is equipped with Coster Mix, an external automatic mixing unit for production of post-foaming gel. The filling cycle is completed by actuator and overcap insertion.
FOR BOTH PRESSURIZATION AND FILLING SYSTEMS
Above and below: AB175 BOV sorter, complete with special elevator for soft filling, reverse roller conveyors, shot device for BOV insertion over cans, sensors for presence of valves on conveyor. This sorter enables production of up to 60 CPM.The shot system is provided with a scroll to select one valve at a time and a spout to thrust it into the pipe for the shot.
1 - Insertion of Bag-On-Valve
into the can. To ensure a safe
automatic handl ing and inser-
t ion of BOVs, Coster has de-
veloped the AB175 BOV sorter
(below, left ) . Immediately after
the BOV insert ion, the machine
checks the proper insert ion of
the BOV into the can (r ight).

2 - Undercup pressurisation and valve
crimping. The
c o m p r e s s e d
gas is filled in-
side the can
outside the bag
and then the
valve is crimped
onto the can.

2 - Valve crimping onto the can. The crimping
head enables
precision to 0.05
mm in crimping
dimensions and
is equipped with
a crimping jaw
that enables 3
mil l ion cycles.
3 - Through the valve pressurisation. The
liquefied propellant is filled through the valve
inside the can
outside the bag
by means of in-
ternally polish-
ed s ta in less
steel high-ac-
curacy pneu-
matic meter-
ing cyl inders.
3 - Pressure check. Optional step to ver-
i fy the value of compressed gas pressure
inside the can.
Left: schematic view of an automatic indexing unit with a production speed up to 40 cans per minute for filling BOVs with pharmaceutical product and compressed gas. The unit is equipped with a diaphragm pump for supplying the product to product filling stations and is placed under a laminar air flow. The filling cycle is completed by actuator and overcap insertion.
