Abstract

La valvola comprende sostanzialmente un primo corpo di forma tubolare (5) che è provvisto di una parete (6) con spessore sostanzialmente costante ed in cui è ricavata almeno una coppia di intagli (7), un secondo corpo di forma anulare (10) nel quale è incorporato un elettromagnete (4) e che presenta una coppia di risalti radiali (11) ed un blocchetto (12) atto a generare una sede per un elemento di connessione elettrica (14) collegato con l'elettromagnete, i risalti suddetti (11) essendo atti ad essere inseriti nei suddetti intagli (7) del primo corpo (5) ed un terzo corpo (15) definente un manicotto assiale (16) atto ad inserirsi all'interno dell'elettromagnete (4) per generare un nucleo ed un collare anulare (17) sporgente radialmente dal manicotto stesso ed atto ad inserirsi all'interno della suddetta parete (6) del primo corpo.
