Fire extinguishing agent: gas (Freon 125, Freon 227, FK-5-1-12, CO2) The KSID overpressure relief valve is designed to protect premises and equipment from overpressure generated during the release of a gas fire extinguishing agent from the gas fire extinguishing modules into the room. KSID-FS is a device, the shutter of which opens when an excess gas pressure in the room is reached, corresponding to the opening pressure of the shut-off valve body, and the medium discharge is released from the protected room into the atmosphere. After the medium discharge has been released to the set pressure, the shut-off element is seated on the seat with a predetermined tightness of the valve, which ensures a longer preservation of the extinguishing concentration of the extinguishing gas in the protected room.
