FIRE DAMPER OZK-DD(15)
General information
Double-acting fire damper OZK DD (El15) with normally open flap (for sequential operation in each state: at fire as a normally open damper and after fire to ventilate the room from products of combustion and extinguishing as a normally smoke damper), according to the requirements of SNiP 41-01-2003 and SP 7.13130.2009.
Type of climatic execution and placement category according to GOST 15150-69. Characteristics of the external environment during operation and storage of the valve:
limit values of operating temperature of ambient air from -30°С to +40°С in the absence of direct impact of atmospheric precipitation and moisture condensation in the damper; the environment must not contain aggressive vapours and gases in concentrations that destroy metals, paint coatings and electrical insulation. The construction of the OZK-DD damper consists of three sections with a refractory material between them. The design allows the valve to open and close without losing its properties after high-temperature exposure.
Fire resistance limit-EI 15.
The OZK-DD valve is equipped with the following types of actuators:
- electromechanical UCP;
- electromechanical Sputnik;
- electromechanical Belimo;
- electromagnetic (EM).
On request it can be equipped with a thermal disconnecting device for 72°C.
