De Dietrich 95361518-Zündventil

This is an ignition valve from De Dietrich, part of the gas valve category for boilers and burners. Parts of this type shut off and meter the gas supply to the burner. They open on command from the burner control and only when the gas pressure switch confirms safe conditions. In premix boilers, a pneumatic gas/air link ties the valve to the fan. The specific article is identified by the manufacturer codes 95361518 and 336.331.003, and by the catalogue article 336.331.003. When selecting a replacement ignition valve, the key parameters are the brand and series, the connection size (typically Rp 1/2" to 2" or flanged), and the coil voltage (commonly 230 V or 24 V AC/DC). The valve may be a single or double solenoid type, with or without slow opening, servo regulation, or integrated filter and regulator (multiblock). It is important to verify the exact function required by the burner control, as ignition valves often serve a separate small burner or a pilot stage in the start sequence. The coil is often replaceable separately from the valve body. Typical failures in such valves include coil burnout, leaking valve seat, drifting outlet pressure, or a seized servo regulator. On a service call, always check for correct voltage at the coil and listen for an audible click when the burner control calls for gas. If the valve body is blocked or the seat leaks, replacement of the entire assembly may be necessary.
