The 4BKR media-separated solenoid valve controls the flow of either ultra-pure or corrosive media, preventing premature failure on wetted-type solenoid valves. This two-way, two-position unit has a low-volume valve cavity and a rolling diaphragm that won't allow chemicals to gather or dead spots to form, which might hinder flow. The valve features a quick-connect interface, allowing it to be mounted in a gang style on a manifold block and is available with orifice sizes of 2.4 mm to 5.0 mm and has Cv ranges from 0.245 to 0.63 in normally open and normally closed functions.
