VK41..V/VK81..V SERIES GAS CONTROLS WITH INTEGRATED 1:1 GAS/AIR REGULATOR FOR COMBINED VALVE AND IGNITION SYSTEM INSTRUCTION SHEET DESCRIPTION VK41..V/VK81..V gas controls perform all the functions required to safely regulate gas flow to the main burner of domestic central heating equipment, warm air furnaces, back boilers and water heaters. VK41..V/VK81..V gas controls hold a first electric on/off direct operator for opening the safety valve of class A or B according to EN161 and a second electric on/off servo operator of class B or C to EN 161. The pressure regulator is in accordance with class B requirement of EN 88. VK41..V/VK81..V gas controls can handle the three gas families, manufactured gas, natural gas and LP gas. SPECIFICATIONS Models VK41.0 series: line voltage gas control with pilot burner connection, two automatic shut off valves and pilot burner connection for direct spark APPLICATION ignition (DSI) or hot surface ignition (HSI) applications, The VK41..V/VK81..V series gas controls with 1:1 gas/air VK41.5 series: line voltage gas control without pilot burner regulator have been developed for application in domestic connection, two automatic shut off valves for appliances with premix burners and automatic ignition. direct spark ignition (DSI) or hot surface For this system, the VK41..V series gas controls have been ignition (HSI) applications, VK81.0 series: low voltage gas control with pilot burner designed to have the S4565 series ignition control attached directly onto the valve. connection, two automatic shut off valves for direct spark ignition (DSI) or hot surface The combined system then provides programmed safe light ignition (HSI) applications, up, flame supervision and regulation of gas flow to the main VK81.5 series: low voltage gas control without pilot burner burner of the appliance. connection, two automatic shut off valves for The VK41..V/VK81..V series can as well be used as stand direct spark ignition (DSI) or hot surface alone in direct burner applications.
