VENTS KRDP Fire Damper

Fire protection pressure control valve

This user’s manual is a main operating document intended for technical, maintenance, and operating staff. The manual contains information about purpose, technical details, operating principle, design, and installation of the KRDP unit and all its modifications. Technical and maintenance staff must have theoretical and practical training in the field of ventilation systems and should be able to work by workplace safety rules as well as construction norms and standards applicable in the territory of the country.

SAFETY REQUIREMENTS

Follow general and special safety regulations during preparation for operation and operation of the valve. Only persons who have studied the device and have been instructed in safety regulations are allowed to install and operate the valve. THE PRODUCT MUST BE DISPOSED SEPARATELY AT THE END OF ITS SERVICE LIFE. DO NOT DISPOSE OF THE UNIT AS UNSORTED DOMESTIC WASTE

PURPOSE

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 fire, the valve cuts off the release of excess pressure from the protected area.

  • L1 = H/n – 150 — blade overhang size beyond the body dimension (mm), where:
  • H – height of the valve [mm];
  • n – number of blades.

VENTS-KRDP-Fire-Damper-fig-2

  • 200 ≤ H = 400 – 1 blade;
  • 400 < H = 800 – 2 blades;
  • 800 < H – 3 blades.

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.VENTS-KRDP-Fire-Damper-fig-3

INSTALLATION AND SET-UP

The valve is installed vertically only (in vestibules or lift shaft enclosures, walls and ceilings with standardized fire resistance limits) and with due regard for the horizontal direction of air flow. 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.

TECHNICAL MAINTENANCE

Maintenance of the valve involves checking its serviceability: free (without jamming) rotation of the flaps; and 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 providing proper protection against precipitation and mechanical damage. Avoid sharp blows, scratches, or rough handling during loading and unloading.
