Abstract

Un gruppo valvolare per caldaie combinate del tipo comprendente un primo circuito per un fluido di riscaldamento, ed un secondo circuito per l'erogazione di acqua calda sanitaria; il gruppo valvolare comprende due valvole a sfera collegabili tramite un passaggio derivato per consentire un funzionamento indipendente dei due circuiti della caldaia, rispettivamente per consentire il loro collegamento ad una rete idrica attraverso lo stesso gruppo valvolare.Una o entrambe le valvole del gruppo comprendono un maschio a sfera provvisto di un passaggio assiale che può essere fatto ruotare tra una prima posizione di apertura in cui il passaggio assiale della sfera è allineato con il passaggio principale della valvola a sfera, una posizione di chiusura, ed una seconda posizione di apertura derivata, ottenibile mediante una rotazione del maschio sferico oltre la posizione di chiusura suddetta.
