It’s fairly straightforward to size and select a valve for dedicated WFI or clean steam applications, however it's not that simple for valves in process applications.
The major wearing component in a regulator or control valve is the diaphragm, and the cost of a diaphragm failure can be catastrophic.
The FDA does not actually "approve" any manufacturers' valve, steam trap, steam trap bellows fill or any other component.
Preventative maintenance depends on the customer. Some run to failure while others change out every 2 years.
Some factors are intrinsic to all regulator designs, but other factors can be controlled by regulator selection or option specification.
All pressure reducing valves exhibit a drop inset point pressure (Offset, Droop) as flow through the valve increases.
A product designed for vessel drains can simplify vessel drain piping, improve SIP heat up time and efficiency and lower CAPex.
How Process Design Engineers have traditionally designed the outlet tubing of large vessels to accommodate clean steam sterilization.
Why do validation temperature alarms occur? How does thermostatic steam trap operation affect temperature validation?
