I am looking for a replacement valve like this. They where installed on Vertex Puratek RODI systems years ago. If you have an old Vertex laying around and want to part it out or can do more internet hunting than I have done let me know. It is 110V driven off the units board so that does make a difference I think. In the picture it is the blue valve on the unit. 1/4 pipe through connectors on it. This is a donor unit that I have I just would like to have another backup since I am scavenging parts now for these units.
