Application conditions
5.2. Operating Conditions
For operation of the solenoid coils Type AC19-..-.-PF09 and Type
AC19-..-.-PF10 observe the following requirements.
5.2.1. Materials
For the selection of materials for the system observe the application-
specific, safety requirements.
Valve body:
DANGER!
Danger of explosion!
If the system is used as a category 2 device, only valve bodies
made of metal can ensure the required safety for the control of
petrol in petrol pumps!
• Use only valve bodies made of metal (brass, aluminium or
stainless steel) for the control of petrol in petrol pumps with
category 2 devices.
• For use in petrol pumps
Metal (brass, aluminium, stainless steel)
• Other applications
Metal (brass, aluminium, stainless steel) or plastic (e.g. polyamide
PA 6 GV ...)
Sheathing of the electrical connection cables:
Type AC19-..-.-PF09
PVC
Type AC19-..-.-PF10 PUR
5.2.2. Minimum dimensions
Valve body:
55 mm x 36 mm x 30 mm (L x W x H)
A larger valve body with improved thermal conductivity may be
used at any time.
5.2.3. Application temperature range:
DANGER!
Danger of explosion!
If the max. permitted temperature values for the coil AC19 are
exceeded, there is a danger of explosion.
• Observe the temperature specifications for the coil
• Observe any restrictions by the max. permitted values for the
solenoid valve combined with the coil.
Temperature values of the solenoid coil AC19
Maximum surface temperatur of the coil at 60 °C ambient tempe-
rature and nominal voltage:
