Questions about the Baumann 84000 Sanitary Control Valve.
What are the typical maintenance issues seen with this control valve. As it has a Diaphragm, Closure Member, this must have a limit on number of cycles or general loss of function over time. Is there guidelines on this?
For the tell tale port, is it possible to put a sensor onto the valve there, such as say pressure etc for a remote warning?
Also, what will the valve signature for this type of valve be in valvelink? will it be much, if any different from a typical non diaphragm?
Good question, but due to variability in application and cleaning process, cycle life expectancy cannot be provided. One of the first visual indications of wear due to cycling is thinning of the PTFE near the outer sealing surface. This cannot be seen without disassembling the valve. See picture below. I was advised by the Fisher product engineer that they hadn't seen a sensor used in the tell tale port. We're unsure of the effects that would have on the o-ring stem seal, or the amount of pressure the o-ring seal would maintain.
