Servo-assisted 2/2-way diaphragm valve
Type 0290 / Article No. 21155
Product description
Valve 0290 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. Depending on the actual applications, there are various diaphragm materials available. The range of bodies additionally includes stainless steel variants. The solenoid coils are encapsulated with a chemically resistant epoxy. ‘Kick and drop’ electronics are 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 protection class IP65 – and NEMA 4X when combined with a stainless steel body.
