Laars Heating Systems V2019600 Valve 318518-761 Efficient LWCO Testing: Simplifies mandatedThe Laars Heating Systems V2019600 Valve is a specialized Dungs GB ND 057 gas train component engineered for high efficiency modulating boiler systems. This zero pressure regulator and safety shut off assembly is designed to maintain a consistent gas to air ratio, supporting a modulation range of up to 1: 10. By regulating the injector pressure toward zero relative to the vacuum generated by the blower, the V2019600 gas valve ensures stable combustion
