8.1. GENERAL CONSIDERATIONS

This valve, just like any other machine, requires maintenance. The instructions in this chapter cover
the maintenance of the valve, the identification and replacement of the spare parts and the disas-
sembly and assembly of the valve. The instructions are aimed at maintenance personnel and those
responsible for the supply of spare parts.
Read carefully the chapter 9. Technical Specifications.
Maintenance work should only be done by qualified persons who are trained and equi-
pped with the necessary equipment to perform this kind of work.
All replaced material should be duly disposed or recycled according to the directives in
effect in each area.
Make sure that the pipes are not under pressure before starting maintenance work.
8.2. MAINTENANCE
To perform maintenance properly is recommended:
- periodic inspection of the valve and its components,
- keeping an operational record of each valve writing down any problems,
- always having spare replacement seals in stock.
Pay special attention to the hazard warnings indicated in this manual during the performance of the
maintenance work.
The valve and the pipes must never be under pressure during maintenance.
¡Burn hazard! Do not touch the valve or the pipes when hot fluids are circulating or when
cleaning and/or sterilization are being carried out.
The time interval between each preventive maintenance may vary in accordance with the work con-
ditions to which the valve is subject: temperature, pressure, number of operations per day, type of
cleaning solutions used, etc.
