Description
Valve 0290 is a servo-controlled diaphragm valve of the S.EV series. The valve opens without differential pressure. The opening process is supported by the fixed coupling of the membrane to the armature. The integrated "soft kick" function causes a material-saving opening. Depending on the applications, different membrane materials are available. The housing range is rounded off by stainless steel variants. The magnetic coils are repressed with a chemically highly resistant epoxy. To reduce the electrical power consumption, all DC versions have a "kick and drop" electronics molded into the coil. In conjunction with a plug in accordance with DIN EN 175301-803 Form A, the valves fulfill the IP65 degree of protection – in conjunction with a NEMA 4X stainless steel housing.
