The dosing valve must be mounted on a support by means of the special threaded hole (M5) on the valve, or by an 

ad-hoc collar.

A good fixing of both the dosing valve to the support and the machine should be guaranteed without vibration and with 

good accessibility for adjustment, cleaning and maintenance.

The ideal working position of the dosing valve is the vertical one, with the nozzle facing down.
