Abstract

Viene descritta una valvola munita di un attuatore con la valvola controllata da un pistone rispondente ad una pressione di fluido in linea durante il movimento di apertura e chiusura. L'attuatore sposta uno stelo di valvola per aprire una valvola a fungo nel pistone per ammettere la pressione in linea in una camera per agire sulle superfici posteriori del pistone per far avanzare il pistone per la chiusura della valvola. Il movimento di chiusura del pistone viene iniziato dall'attuatore e continuato mediante la pressione di fluido in linea. Una valvola sullo stelo controlla la comunicazione della camera, in cui il pistone viene portato, con una uscita per chiudere la camera per effetto di pressurizzazione provocando l'entrata in sede anteriore del pistone. Il movimento di apertura della valvola dell'attuatore chiude la valvola a fungo montata al pistone e fa sfiatare la camera permettendo alla pressione di fluido in linea di spostare il pistone posteriormente verso una posizione aperta. Un'altra forma della valvola munita di attuatore include una carcassa che definisce passaggi longitudinali che mettono in comunicazione un ingresso con una uscita.
