PURPOSE
DELIVERY SET
The valve is intended for use in ventilation and air conditioning systems in public and industrial buildings, in emergency smoke ventilation
systems to ensure evacuation of people from premises at the initial stage of a fire.
The valve automatically opens at the required pressure difference (design pressure difference) to allow air to flow freely from the space
where the air is pressurised (e.g. stairwell or elevator shaft) to the space where the pressure is lower (e.g. hall, room).
In case of a fire, the dual action of the design features makes the valve a fire protection valve with a fire resistance rating of EIS 120.

TECHNICAL MAINTENANCE
Maintenance of the valve involves checking its serviceability: free (without jamming) rotation of the flaps; reliability of installation. The
valve maintenance intervals should correspond to the established maintenance periods for the fire protection equipment complex of
the operated facility.
The fusible link triggering mechanism is restored by replacing the fusible link (in the absence of fire impact).
STORAGE AND TRANSPORTATION REGULATIONS
• Use suitable hoist machinery for handling and storage operations to prevent possible damage to the unit.
• Follow the handling requirements applicable for the particular type of cargo.
• The unit can be carried in the original packaging by any mode of transport provided proper protection against precipitation and
mechanical damage. Avoid sharp blows, scratches, or rough handling during loading and unloading.
INSTALLATION AND SETUP
The valve is installed in ventilation ducts or in intersections of enclosing structures and closes in the event of a fire.
Valve’s position in the valve space is vertical (air flow is horizontal).
Visually inspect the valve before installing it.
Repair any damage or dents caused by improper transportation or storage.
The valves should be configured to the required working pressure after their installation during the adjustment (commissioning) of the
pressure generation ventilation system.
UNIT DESIGN AND OPERATING PRINCIPLE
The valve consists of a rectangular galvanized steel mounting casing (1). Inside the casing there is one or more flaps made of heat-
resistant material (2) of rotary type, a spring mechanism (3) for adjusting the valve opening start. The adjustment is performed during
commissioning.
In case of a fire, the valve design ensures that the blade is automatically locked at the stops by melting the fusible link (4). The valve’s
tightness in case of fire is ensured by a tape that is fixed around the perimeter of the blade and expands at high temperatures.
