IRY Dimensions Description The valve is designed for installation at a wall or in a ceiling. It can be used for new-build and for replacement. Its smart grip function ensures an easy installation. Its unique sound data ensure an optimum sound level. The valve consists of two parts; the valve body (IRY) and the flat front plate (IRYFP). The valve body is fixed to the duct system or a valve socket via flexible spring wings. The front plate is attached to the valve body via springs. There are standard front plate shapes: ROUN a circle, OW a square with sligthly bulged edges, SQU a square, ELLI an super ellipse. RECT a rectangle, Special shapes are possible on request. It is recoended that the valve is mounted in the frame ILVRU. The product will also fit in the valve frames VRGU, VRGM, VRFU, VRFM and the products U GJUT, and TCPU GJUT. The valve body has to cover the brim of the product it is fitted into. Therefor the maximum diameter of the brim for Ø0 is,, for Ø is, and for Ø0 is,. Can be equipped with a blanking off sector plate for or way air flow. Maintenance The visible parts can be wiped off with a damp cloth.
