La 5282 è una valvola servoassistita a membrana. Per il funzionamento della valvola è 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. I corpi valvola sono disponibili in acciaio inox e ghisa grigia. La funzione della valvola può essere commutata facilmente da NC a NO mediante la rotazione del pilota 3/2 vie. Le bobine magnetiche sono rivestite con resina epossidica resistente agli agenti chimici applicata a pressione. La 5282 è dotata di un comando manuale utile per la messa in servizio e i test. Con l'utilizzo di un connettore conforme alla normativa DIN EN 175301-803 forma A, le valvole soddisfano i requisiti di NEMA 4X.
