The energy yield during combustion is only perfect with the optimum mixture ratio of gas and air. In condensing units, the gas valve is a key component for combustion control. It provides exactly the gas quantity which the gas-air control system requires for efficient combustion and also ensures safe operation thanks to the controlled gas supply. The gas valve range from ebm‑papst covers a heat output range of 1.5 to 762 kilowatts and was specially designed for our system solutions in condensing technology. Regardless of whether the control system is pneumatic or electronic, it is crucial in both combustion systems that all components are carefully coordinated: Blower, venturi, burner control and, of course, the gas valve. Our gas valve range is suitable for the natural and liquid gases used in gas heating technology. This also applies to hydrogen. All our gas valves are tested by the German Technical and Scientific Association for Gas and Water (DVGW) for an admixture of 20 percent of the green energy source of the future. Mechanical valves are used in our CleanEco pneumatic gas-air control system . The gas is drawn in by the vacuum generated by the gas blower in the venturi. To ensure that the gas valve supplies the exact fuel quantity, it can be adjusted using two adjusting screws: The offset (zero point shift) can be configured on the servo controller – pressure fluctuations in the supply network are compensated for in this way. The setting on the main flow regulator can be used to adjust the desired gas quantity to match the gas quality.
