The extinguishing agent containers are filled through the valve output.
To protect against impermissibly high pressure, each valve is equipped with a burst disk
device.
Each valve includes a pressure gauge connection with an integrated non-return valve and
control connection.
The quick release valve is a total discharge (TD) valve, meaning that following activation, the
valve remains open until the extinguishing agent container is empty (with the exception of
the remaining residual pressure; see below).
If the pressure in the extinguishing agent container is approximately 22 psi (1.5 bar), the valve closes
again automatically. There is subsequently always a residual pressure in the extinguishing agent con-
tainer.
