Pneumatic Bag On Valve Aerosol Filling Machine For Sunscreen Spray
/ Protection Spray
- Bag On Valve Aerosol Filling Machine is specifically designed for
bag on vavle aerosol products filling, it is PLC controlled with a
frendly touch screen interface, comparing with previous pneumatic
control one, this version is improved a lot in efficiency,
intelligence, parameters setting, process supvision and trouble
- There are two heads seated on the working table, the first head
combines the function of vacuumizing, prppellant filling and
criimping, more economic propellants are optional for customer such
as N2, CO2, Air or even comperssed air.
- The second head is aiming to charge the liquid material into bag
through the valve, since material is insolated into bag and will
not touch propellant, thus this machine is widely used for
pharmaceutical, food, cosmetic and other bag on valve products
manufacturing. And there is no any limitration about water base,
oil base or alcohol based liquid.
1. Raw material will be filled into inside of bag, entirely
separate from can body, which prevents the trouble of the can leak
due to raw material corrosion.
2. BOV propellants are N2 or compressed air, safe and clean. When
operation, valve will be open and make compressed air in the can to
force the raw material out of bag. When raw material is fully
ejected, compressed air still retains in the can and then be used
for repeated filling.
This model BOV filling machine is widely applied in medicine,
health, fire, cosmetics and other industries, such as water-based
release agent, water-based spray paint, photocatalyst, nasal spray,
water spray, water-based fire extinguishing agent, tear gas,
shaving foam etc. Besides, we could customize paste filling machine
for high viscosity material.

Bag on valve working process: Crimping&gas filling and liquid filling
How does Bag on Valve Work
Bag-on-valve is a relatively recent development in aerosol
delivery.The principle is simple in that, instead of filling a can
with a mix of liquid material and propellant(usually inflammable) ,
the liquid material is sealed inside a collapsible inner bag and is
expelled by a pressurised gas. Unlike traditional aerosols, the gas
remains inside the can and, as it is usually pressurised air, the
gas has no 'end-of-life' environmental impact.
BOV consists of an aerosol valve with a welded bag. The product is
placed inside the bag while the propellant is filled in the space
between bag and can. The product is dispensed by the propellant
simply squeezing the bag when the spray button is pressed, the
product is squeezed out of the bag by the compressed air/nitrogen,
which creates the dispensing as a spray, cream or gel.
Therefore, your product keeps its integrity, remaining separated
from the propellant at all times.
