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.

 

Bag on Valve Machine Introduction

 

  • This 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 shooting.

 

  • 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.
