10.1 Product description and operation
Fig. 10.1
Normally closed 3-way 2-position solenoid valve.
When the connected filter system is in operation, the solenoid is
activated and compressed air is supplied to the cleaning system
of the filter (port P and A are open). If there is a fire alarm or
power failure, the solenoid will return to its normally closed (NC)
position, closing port P and opening port R. In this position
compressed air escapes from the filter and it is unable to
execute a filter cleaning procedure. This prevents fresh oxygen
from reaching the filter in case of fire.
