Llaves y grifos de llenado, válvulas de vaciado y racores de carga para calderas murales de gas Vaillant, Saunier Duval, Junkers y Bosch, Immergas, Ferroli, Beretta, Ariston y Roca. Con la llave de llenado se repone el agua del circuito de calefacción hasta 1-1,5 bar; cuando gotea o no cierra bien, la presión de la caldera sube sola y acaba descargando la válvula de seguridad.
Muchas llaves parecen iguales pero cambian la rosca o el eje: busca siempre por el código del despiece de tu caldera. Piezas relacionadas: válvulas de seguridad y manómetros. Ver todos los recambios para caldera.
