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. In combination with a plug to DIN EN 175301-803 Form A, the valves satisfy degree of protection IP65 – and NEMA 4X when combined with a stainless steel body.
