Valvola servoassistita a membrana a 2/2 vie
Tipo 0290 / Numero ID 298137
Descrizione del prodotto
La valvola 0290 è una valvola a membrana servoassistita della serie S.EV La valvola si apre senza pressione differenziale. Il processo di apertura è supportato dall'accoppiamento fisso della membrana all'ancoraggio. La funzione integrata "Soft-Kick" garantisce un'apertura senza impatto sul materiale. A seconda delle applicazioni sono disponibili diverse combinazioni di materiali per la membrana. La gamma degli alloggiamenti offerti si completa con varianti in acciaio inox. Le bobine magnetiche sono rivestite in resina epossidica ad alta resistenza applicata a pressione. Per ridurre la potenza assorbita, tutte le varianti DC presentano, fusa all’interno della bobina, un'elettronica "kick and drop". In combinazione con il connettore conforme alla normativa DIN EN 175301-803 forma A, le valvole soddisfano i requisiti del grado di protezione IP65 - in combinazione con un alloggiamento in acciaio inox NEMA 4X.
