Publication DIFFUSERS section 2 SEPT 2005 PART G R Air Valves supply and exhaust ventilation systems supply and extract valves type finish KE / White (SEE) / 160 / 3 quantity EXAMPLE : size d + 7 50 D d (o/s) DIMENSIONS (mm) Size D d 100 130 98 125 155 123 150 178 148 160 190 158 200 236 198 introduction fixings finishes The K series range of small format supply and extract air terminals are ideally suited for low air volume applications such as domestic residences or hotel rooms. The range comprises a supply valve (type KE), two styles of extract valve (types KK and KS) and an extract fire damper (type KF). All models have an aerodynamically profiled, adjustable and lockable centre cone which is designed to provide an easy method of flow regulation, with minimal influence on the noise level. Gloss white epoxy stove enamelled paint is offered as a standard finish to provide maximum corrosion resistance in damp environments. A full range of colours are however available in either the BS or RAL ranges. See Part I for details. The valves are supplied with an easy fit bayonet collar which can either be rivetted to the duct or screw fixed to the mounting surface. ordering details mounting collar type K Supply and Extract Valves DESIGN FEATURES 2 Dia D H Max Dia d 6 Datum + _ 6 + _ Dia D H Dia d Datum Dia D Dia d H Datum 6 + _ Dia d Dia D Datum 6 + _ Mounting Collar Fusible Link closes centre cone at a temperature of 74oC DIMENSIONS (mm) Size D d H KE100 137 94 47 KE125 161 110 49 KE150 202 135 60 KE160 212 145 60 KE200 249 194 75 DIMENSIONS (mm) Size D d H KK100 137 75 70 KK125 161 100 85 KK150 202 120 85 KK160 212 130 85 KK200 249 157 110 DIMENSIONS (mm) Size D d H KS100 134 87 91 KS125 160 108 97 KS150 191 130 85 KS160 191 130 85 KS200 241 177 104 DIMENSIONS (mm) Size D d KF100 140 99 KF125 165 124 KF160 200 159 KF200 250 199 Supply and Extract Valves DIMENSIONS design features TYPE KE Supply air valve TYPE KK Extract air valve TYPE KS Low Noise Extract air valve TYPE KF Extract Fire Damper R 3 AIR FLOW RATE (l/s) SIZE PARAMETER CONE POSITION PRESSURE FACTOR 10 15 20 25 30 40 50 60 70 80 90 -6mm +6mm KE80 KE100 KE125 KE150 KE160 KE200 THROW (m) PRESSURE LOSS (Pa) NR LEVEL THROW (m) PRESSURE LOSS (Pa) NR LEVEL THROW (m) PRESSURE LOSS (Pa) NR LEVEL THROW (m) PRESSURE LOSS (Pa) NR LEVEL THROW (m) PRESSURE LOSS (Pa) NR LEVEL THROW (m) PRESSURE LOSS (Pa) NR LEVEL 1.0 1.5 1.9 2.2 25 55 95 140 15 23 30 35 9.0 0.4 0.7 1.1 1.6 1.9 2.2 2.7 12 25 40 58 90 150 20 25 35 42 3.3 0.4 1.1 1.5 1.9 2.1 2.6 3.1 3.4 3.6 12 20 30 55 85 120 170 20 25 30 35 3.3 0.5 0.6 0.9 1.2 1.6 1.9 2.2 2.5 2.7 10 15 22 40 70 90 130 180 17 25 32 35 42 2.2 0.4 0.6 0.8 1.0 1.2 1.6 1.8 1.9 2.1 2.3 12 17 25 38 60 85 105 140 200 15 23 30 33 37 43 2.9 0.4 0.6 0.9 1.2 1.6 1.9 2.2 2.5 2.7 10 15 22 40 70 90 130 180 17 25 32 35 42 2.2 0.4 SIZE PARAMETER KK80 KK100 KK125 KK150 KK160 KE200 KK200 AIR FLOW RATE (l/s) CONE POSITION PRESSURE FACTOR 10 15 20 25 30 40 50 60 70 80 90 -6mm +6mm PRESSURE LOSS (Pa) NR LEVEL 1.9 0.6 22 50 82 140 15 23 30 1.4 0.6 15 32 60 90 120 200 15 21 24 30 PRESSURE LOSS (Pa) NR LEVEL 1.5 18 31 48 70 120 180 15 21 30 PRESSURE LOSS (Pa) NR LEVEL 1.4 17 34 42 70 110 170 17 24 30 PRESSURE LOSS (Pa) NR LEVEL 1.4 17 34 42 70 110 170 17 24 30 PRESSURE LOSS (Pa) NR LEVEL 1.5 0.65 50 75 100 140 170 22 27 30 35 PRESSURE LOSS (Pa) NR LEVEL The following data is all based on an optimum centre cone position 6mm below the level of the outer frame. Where applicable, correction factors may be applied for other cone settings. Jet throws are given in meters to a terminal velocity of 0.2m/s. Noise data is expressed in terms of NR level with a room absorption factor of 8db. basis of data noise levels throws PERFORMANCE DATA Supply and Extract
