Choosing and fitting
Parts of this type are selected by connection size (typically Rp 1/2" to 2" or flanged), coil voltage (230 V or 24 V AC/DC), and function (e.g., single or double solenoid, slow opening, servo-regulated, or multiblock). Before ordering, verify the gas type, pressure range, and electrical supply compatibility. Installation involves standard threaded connections, and the coil is often replaceable separately from the valve body.
Signs of failure
Common failure modes include a burnt-out coil, leaking seat, drifting outlet pressure, or seized servo regulator. Symptoms may include the burner failing to ignite, gas flow continuing when it should stop, or inconsistent flame. Check the coil continuity, seat sealing, outlet pressure stability, and servo regulator movement.
