7.2 Lubrication
Lubrication operations have to be carried out (see periodic check maintenance), using conductive type grease
pastes on the following parts:
- Connecting shaft;
- Earth wiring contact screw.
N.B.:
A routine lubrication cycle is only recommended for the CRGX electromechanical control, with grease
suitable for ATEX applications applied on the bronze block approx. every 300 opening/closing cycles.
7.1 Cleaning the valve
Clean the outside part of the valve using a vacuum cleaner to prevent dispersal of dust in the environment and
in the surrounding area, or use a moist cloth.
Do not use compressed air under ATEX condition.
Wash the valve, after vacuuming the dust, with a low-pressure water jet.
Before start-up the valves for food applications (model F and P), has to be subjected to cleaning and sanitation
by means of a woven/non-woven cloth and sanitizer spray.
