The BOV (Bag-on-Valve) filling process is two stage. The first stage is to pre-gas around the bag and immediately crimp and seal the bag, the second stage is to inject the product through the valve into the bag. The propellant gas used in BOV (Bag-on-Valve) Filling Machines is compressed air or nitrogen, and BOV (Bag-on-Valve) Filling Machines do not need to be installed in special rooms. Products filled on these machines include creams, lotions, shaving gels, pharmaceutical products including nasal sprays, technical products including fire extinguishers.

Semi-Automatic BOV (Bag-on-Valve) Filling Machines are for producing samples and small production runs. This machine is fully safety guarded, and ideal for semi-automatic production of BOV aerosols. Standard work stations include UTC (under the cup) Crimper/Gas Filler and TTV (through the valve) Product Filler. The semi-automatic BOV (Bag-on-Valve) Filling Machine production unit offers a value for money solution for filling BOV aerosol products.

Both semi-automatic and automatic versions of BOV (Bag-on-Valve) Filling Machines are offered. Semi-automatic BOV (Bag-on-Valve) Filling Machines can be supplied as a table top machine or as a free standing machine. Automatic rotary single or double indexing BOV (Bag-on-Valve) Filling Machines can be integrated into an existing line or be the central part of a new filling line.
