Fire Extinguishing Valve OZK-2m(120)
General information
The valve is certified in accordance with the procedure established by the legislation. Fire resistance limit of the valve OZK-2m(120):
- in the mode of normal open (fire retarding) valve - Ei120;
- in the mode of normal closed valve - Ei120;
- in the mode of smoke exhaust valve - Ei120.
Fire damper of ventilation systems of buildings and constructions OZK-2m(120) (hereinafter referred to as the damper) by its functional purpose can be used as a fire retardant with normally open flap (NO) and smoke damper with normally closed flap (NC), according to the requirements of SNiP 41-01-2003 and SP 7.13130.2009.
Type of climatic execution and placement category U3 according to GOST 15150-69. Limit values of operating temperature of ambient air from -30°C to +40°C under condition of absence of direct impact of atmospheric precipitations.
The valve is available in rectangular or circular cross-section. It is installed in openings or places where ventilation systems pass through fire barriers.
The damper is operable in any spatial orientation.
The valve should not be installed in ventilation ducts of rooms of A and B category of explosion hazard, local suctions of explosion-hazardous mixtures.
The valve is made of galvanised steel.
The construction of the valve consists of two sections, between which there is a fireproof material, which fulfils the role of a temperature joint. The valve consists of section No.1 and section No.2 of the body, damper, actuator and protective cover protecting the actuator during installation and operation of the valve.
* Protective cover is available on request.
The valve is equipped with the following types of actuators:
- electromechanical FS, FSN (SPUTNIK);
- electromechanical BLF (BFL), BLE;
- electromagnetic EM.
