Valvola del gas Kromschroeder CG15R03VW6CWVG20/G15Z (97956335)

A gas valve of this type serves as the primary shut-off and metering device for gas supply to a burner. It opens only when the burner control signals and the gas pressure switch confirms safe pressure. In premix burners, a pneumatic gas/air link may connect the valve to the fan for ratio control. Such valves are selected by brand and series, connection size (typically Rp 1/2" to 2" or flanged), coil voltage (commonly 230 V or 24 V AC/DC), and function – for example, single or double solenoid, slow opening, servo regulation, or a multiblock combining a filter and pressure regulator. Typical field issues include coil burnout, leaking valve seat, drifting outlet pressure, and a seized servo regulator. The coil is often replaceable separately from the valve body, which simplifies certain repairs. This specific article is the Kromschroder CG15R03VW6CWVG20/G15Z gas valve, bearing catalogue article 624.322.158 and manufacturer codes 97956335 and 624.322.158. When sourcing a replacement for a valve of this type, confirm the connection size, coil voltage, and whether the valve is a simple solenoid or a regulated block. Also check that the valve's response time matches the burner sequence – some applications require a slow-opening valve to prevent pressure surges. If the valve is part of a premix system, ensure the pneumatic link is compatible with the fan characteristic. Always verify the gas type and supply pressure before installation.
