5.10 Inspection

Important

When installation is complete, authorized personnel must carry out a general test to make sure the 

safety conditions have been complied with completely.

The authorized personnel must also check:

- That no tools or other material have been left inside the valve;

- That the fixing screws have been tightened using the prescribed torque.

Before starting to operate the valve:

-  Ensure that the plant in which the valve is installed complies to the Directive 2006/42/EC and the relevant 

directives, the safety standards in force and those specifically applicable.

-  Make sure the inlet and outlet spouts of the valve are connected to the final equipment or plant in order to 

prevent access to hazardous areas.

- Ensure that the operating conditions are complied with.

-  When sizing the valve, check for any chemical incompatibility between the material and the components of 

the valve.

- Make sure that the food versions (model GF) were properly cleaned and sanitized.
