6 Dimensions, application, material, product code Dimensions øf ød The valve body is equipped with an EPDM rubber sealing gasket. The valve can easily be adjusted to the desired position by rotating the disc. The adjustment position is secured by pressing a locking button (material ABS) to the disc. The diffusion pattern is chosen by preventing the supply air flow to a certain direction with the sector plates (material ABS) delivered with the product. H C1 C2 øe ød Size ØD Ød H C1 C2 ØE ØF [mm] [mm] [mm] [mm] [mm] [mm] [mm] Application and function KTI supply air valve (pat. pend.) covers a wide air volume range; l/s, for duct sizes mm. The product can be quickly installed directly into the spiro duct without a mounting ring. KTI can be installed in two ways: off the installing surface (figure 1) or close to surface (figure 2). When installing the KTI in the lower position (figure 1) the ceiling around the valve stays clean. The diffusion pattern of supply air is adjusted with the sector plates (2 pieces.) delivered with the product. There are three alternatives: 360, 270 (1 plate) or 180 (2 plates) blow. KTI can be measured, adjusted and locked to the desired adjustment position without unfastening the product from duct. s Material and surface finish The valve are made from hot-dip galvanized steel sheet. The devices are powder-coated for a high surface finish and good impact and scratch resistance. Standard colour White RAL Other colours on request.
