Abstract

Viene descritta una disposizione valvolare a sede doppia con un corpo valvolare, entro il quale sono disposti funghi di valvola e sedi valvolari. Due funghi di valvola sono accoppiati con uno stelo di valvola ed atti ad essere premuti sulle sedi valvolari; e formano allo stato chiuso uno spazio, il quale è collegabile con il primo condotto del fluido sotto pressione ed è collegabile, con un corrispondente azionamento dello stelo di pistone con contemporaneo sollevamento di funghi di valvola per le sedi valvolari attraverso le sedi valvolari ad accoppiamento di fluido sotto pressione, con uno spazio interno del corpo valvolare, collegabile con il secondo condotto del fluido sotto pressione.Secondo l'invenzione per l'azionamento dello stelo di valvola è previsto un attuatore, costituito da un pistone operativo (7, 7'), da uno spazio cilindrico (13, 13') e da un condotto (S) del fluido sotto pressione, in questo sboccante, e lo spazio interno (11,11') collegabile con il secondo condotto del fluido sotto pressione, presenta un collegamento continuo ad accoppiamento di fluido sotto pressione con l'intero spazio cilindrico (13, 13') dell'attuatore.
