Safety
Pressure relief dampers are closed in idle position. If there is an increase or drop in pressure
over or under a specified value, the pressure relief dampers open and ensure that the pressure
is relieved.
Check valve
Check valves permit the flow of extinguishing agent in the flow direction and prevent it in the
opposite direction. They are located at the transitions of the hoses to the manifold.
Pilot pressure relief device
The pilot pressure relief device dissipates a slow increase in pressure via a vent bore. Slow gas
leaks can occur, for example, if there are leaks in the extinguishing agent container. The pilot
pressure relief device closes automatically if there is an abrupt pressure increase through an
activation, so that the pilot line of the respective extinguishing zone is closed at flooding.
Manifold safety valves
Manifold safety valves are attached wherever dangers exist due to unreliably high pressure.
In the event of impermissibly high pressure the safety valve ensures pressure compensation.
The blow-off lines connected to the safety valve safely dissipate the medium.
Protective valve caps
Protective valve caps are used to protect sensitive components (e.g. valves) of the extinguish-
ing agent containers. They prevent the valves from being damaged during transport. The pro-
tective valve caps must be attached before each transport.
Locking nut
The locking nuts seal the valve outlets, e.g. during transport or storage, so that extinguishing
agent does not escape in the event of unintentional activation. They are provided with vent
bores in order to enable a controlled release of pressure in case of unintentional activation.
The locking nuts are connected to the valves by means of loss protection devices.
