The KVZ-L fire shut-off valve is installed in ventilation systems as a partition separating the fire zone from the rest of the building. It has a fire resistance of up to 4 hours EI240(ve i<->o)S, which means that in the event of a fire the sash will provide airtightness, insulation and fire resistance to other parts of the building for at least 240 minutes.

The product has been thoroughly tested by a team of third-party experts, and its high reliability, durability, tightness and efficiency are confirmed by a certificate of compliance with the following standards: PN-EN 15650, PN-EN 13501-3, PN-EN. 1366-2 and PN-EN 1751.

The leaf has a single-plane design and a large effective surface. It can be installed in rigid walls with a thickness of 150 mm. It is equipped with a high-quality electric drive with a Belimo return spring, which makes the closing and opening of the partition always reliable and precise, and thanks to a smooth range of sizes (from 200mm x 200mm to 1000mm x 1000mm), the sash can be flexibly adjusted to the appropriate areas of the project.
