The 0290 valve is a servo-assisted diaphragm valve of the S.EV series. The valve opens without differential pressure. The opening process is facilitated by the fix coupling of the diaphragm to the magnetic core. The integrated ‘soft-kick’ function ensures gentle opening. Various diaphragm materials are available depending on the actual application. Stainless steel body variants complete the offering. The solenoid coils are moulded with a chemically resistant epoxy. A 'kick and drop' electronics assembly is moulded into the coil of all DC variants to reduce electrical power consumption. NEMA 4X is available on request.

Servo-assisted diaphragm valve up to DN50
Fix-coupled diaphragm opens without differential pressure
Vibration-proof, block screwed coil system
Energy-saving power reduction for all DC variants
