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.
