Riello burners are widely paired with valve trains manufactured by the German company DUNGS. These valve trains are primarily used for the safe shut-off, regulation, and stabilization of gas flow. Common models include the MB-DLE, DMV-D, and DMV-DLE series.
Common Models and Features
MB-DLE Series (Multifunctional Gas Combination Valve Train): Commonly used for small to medium-sized burners (e.g., MB-DLE 405, 410, 412). It integrates a filter, pressure regulator, two main valves, and a bypass valve into a single, compact valve body. The "DLE" designation indicates a slow-opening type, suitable for the "soft start" of a burner.
DMV-D / DMV-DLE Series (Dual Solenoid Valve Train): Commonly used for higher-capacity burners (e.g., DMV-D 507, 512, 520). Internally, it contains two independent automatic shut-off valves within a compact structure. The "D" designation indicates a fast-opening/fast-closing type, while "DLE" indicates a slow-opening type.
Technical Specifications and Parameters
Maximum Operating Pressure: Typically 360 mbar or 500 mbar (depending on the specific model).
Protection Class (IP Rating): Mostly IP54, offering excellent protection against dust and splashing water.
Ambient Temperature: The standard operating range is typically between -15°C and +60°C.
Common Maintenance and Repair Parts
After extended periods of operation, the valve train may require the replacement of wear parts:
Solenoid Coils: Such as the Mag.Nr series (common models include Nr100, Nr200, Nr300, etc.).
Gas Pressure Switches: Used to monitor gas pressure within the pipeline (e.g., DUNGS GW 50 A5, GW 150 A5, etc.).
Leak Detection Devices: For high-capacity Riello burners, the system is typically paired with a DUNGS VDK200 leak detector.
