The pressure reducer may only be used in accordance with system approval in stationary argon and nitrogen fire extinguis-hing systems with a maximum working pressure of 235 bar. It is installed between the upstream pipework and the downstream pipework. Any combinations of inlet and outlet thread is possible.

Application
The check valve KRV-2 may be used only in accordance with system approval in stationary argon, nitrogen, IG-55, IG-541 and CO2 fire extinguishing systems.
It is installed between the valve of the extinguishing agent cylinder and the manifold.

The selector valve MX-BV DN 25/40/50 is used in accordance with the “documentation of special extinguishing systems” in fixed CO2, argon, nitrogen, IG-55 and IG-541 high pressure fire extinguishing systems or MX 1230/200 fire systems respectively.
In case of fire the selector valve DN 25/40/50 is used for flooding selected extinguishing zones.

The AVS-E1 FF deluge valve set is crucial in controlling the flow of water in a deluge system. These systems are often used in areas where there is a high fire risk.

The nozzle ARGE may only be used in accordance with system approval in stationary argon and nitrogen (no CO2) fire extinguishing systems. The nozzle is used for the pro-tection of small rooms or small enclosed objects e.g. EDP-equipment, control cabinets or cable floors. They distribute the extinguishing agent evenly in the extinguishing zone in the calculated flooding time.
The calculation is carried out via the Minimax calculation program.

The pressure reducer may only be used in accordance with system approval in stationary argon and nitrogen fire extinguis-hing systems with a maximum working pressure of 365 bar. It is installed between the upstream pipework and the downstream pipework. Any combinations of inlet and outlet thread is possible.

The check valve KRV-2 may be used only in accordance with system approval in stationary argon, nitrogen, IG-55, IG-541 and CO2 fire extinguishing systems.
It is installed between the valve of the extinguishing agent cylinder and the manifold.

The ball valve enables the pilot pipe to be shut off.
At the same time the pilot pipe is vented to preclude an un-controlled rise of pressure.
When the system is in normal operation the ball valve is lok-ked with a padlock in the eyelet so that the marking „Betrieb“ (operation) is visible.

The check valve KRV-1 may only be used in accordance with system approval in stationary CO2, argon, IG-55, IG-541 and nitrogen fire extinguishing systems.
It is installed between the valve of the extinguishing agent cylinder and the manifold.

The manifold selector valve MX-BV DN65/80/100 pneumatic is used in accordance with “documentation of special extin-guishing systems”
