INSTRUCTION SHEETVK41..R/VK81..R seriesGAS CONTROLS WITH INTEGRATED GAS/AIR MODULEFOR COMBINED VALVE AND IGNITION SYSTEMEN1R--9137 9808R6--NEAPPLICATIONThe VK41..R/VK81..R series gas controls with integratedgas/air module have been developed for application indomestic appliances with premix or atmospheric burners andautomatic ignition.The gas/air module is designed to amplify and modulate theoutlet gas pressure by means of a pneumatic link between thegas and air flow by using the air pressure difference.For this system, the VK41..R series gas controls have beendesigned to have the S4565 series ignition control attacheddirectly onto the valve.The combined system then provides programmed safe lightup, flame supervision and regulation of gas flow to the mainburner of the appliance.The VK41..R/VK81..R series are used in a system context inconjunction with fan control and a direct spark ignition (DBI)control.The VK41..R/VK81..R series are approved in accordance witheuropean standards.DESCRIPTIONVK41..R/VK81..R combined gas controls perform all thefunctions required to safely regulate gas flow to the mainburner of domestic central heating equipment, warm airfurnaces, back boilers and water heaters.VK41..R/VK81..R combined gas controls hold a first electricon/off direct operator for opening the safety valve of class A orclass B according to EN161 and a second electric on/offservo operator of class B or class C to EN 161.VK41..R/VK81..R combined gas controls comply with theadditional requirement for class J valves according to EN 161.The pressure regulator is in accordance with class Brequirement of EN 88.VK41..R/VK81..R combined gas controls can handle the threegas families, manufactured gas, natural gas and LP gas.SPECIFICATIONSModelsVK41.. series: line voltage, two automatic shut off valvesfor direct spark ignition (DBI) or hot surfaceignition (HSI) applications.VK81.. series: low voltage, two automatic shut off valvesfor direct spark ignition (DBI) or hot surfaceignition (HSI) applications.Suffix letterR: fast opening, with integrated gas/air modulePipe connectionStraight or elbow flanges.Torsion and bending stress according to EN 126 group 2Ambient temperature0 ... 60 _C for combined valve and ignition control0 ... 70 _C for stand alone valveDimensionsSee fig. 1.Pressure regulation functionClass B according to EN 88Air pressure connectionsM11 x 1Subject to change without notice.
