The valve 0290 is a servo-controlled diaphragm valve. The valve opens without differential pressure. The opening process is supported by the fixed coupling of the diaphragm to the armature. The integrated "soft-kick" function ensures that the opening is gentle on the material. Depending on the applications, different diaphragm materials are available. The housing range is rounded off by stainless steel variants. The solenoids are pressed with a chemically highly resistant epoxy. To reduce the electrical power consumption, kick and drop electronics are encapsulated in the coil in all DC variants.
