ATTENTION 

The ambient temperature (specified on the label) in which the pneumatic actuator of 

the valve can work is between: 

- 20 °C / + 70 °C 

std diaphragm EPDM

 

- 50 °C / + 80 °C 

std diaphragm VMQ60

 

 

Obviously, the maximum surface temperature is the ambient temperature  

 

ATTENTION

 DO NOT OPEN THE EQUIPMENT IN AN EXPLOSIVE ATMOSPHERE. 

BEFORE OPENING, ENSURE THE EQUIPMENT FLUID INSIDE IS NOT PRESSURISED AND 
THAT IT HAS APPROPRIATELY COOLED. 
Carry out every maintenance operation, according to the manual, in total safety! 

 

 

6.2 - ASSEMBLY INSTRUCTIONS - CALIBRATION AND MAINTENANCE 

For assembly, see section 2 
For calibration see section 3 - point 3.4 
For maintenance see section 3 - point 3.4 

6.2.1 

– VALVE GROUND 

Connect the ground as indicated in the figure.
