Vaillant Gas Valve Section (0020110996)

The Vaillant Gas Valve Section 0020110996 is a brand new, genuine Valliant spare part with a Vaillant manufacturer's guarantee. The gas valve is a device that regulates the flow of gas within a heating system for optimal performance and ensuring the correct operational temperature is reached. It works by controlling the volume of gas supplied via an open / close valve when an instruction is sent from the PCB to signal the demand. When signalled, the valve opens, allowing the flow of gas into the burner or pilot assembly.
