Valvola servoassistita a membrana a 2/2 vie
Tipo 6281 / Numero ID 298053
Descrizione del prodotto
La 6281 è una valvola a membrana servoassistita. Per il corretto funzionamento della valvola è sempre necessaria una pressione differenziale minima. Sono disponibili svariate combinazioni di materiali della membrana e del corpo e funzionamenti diversi. Il corpo standard in ottone soddisfa tutti i requisiti europei in materia di acqua potabile. Per ulteriori mercati sono disponibili corpi valvola in ottone resistente alla dezincificazione e in acciaio inox. Le bobine magnetiche sono incapsulate con resina epossidica resistente agli agenti chimici. Per contenere il fabbisogno energetico, tutte le bobine possono essere fornite con una riduzione elettronica della potenza. La valvola può essere equipaggiata con un comando manuale per la manutenzione e la messa in servizio facilitate. Con l'utilizzo di un connettore conforme alla normativa DIN EN 17301-803 forma A, le valvole soddisfano i requisiti del grado di protezione IP65 e NEMA 4X.
