Manufacturer profiles associated with Stem.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Sanitary stems require electropolished surfaces with Ra ≤ 0.8 μm to prevent bacterial growth and facilitate cleaning in place (CIP) processes.
The stem uses multiple sealing points including primary stem seals, secondary backup seals, and sometimes bellows seals to create a leak-proof barrier while allowing smooth rotation.
For highly corrosive media, duplex stainless steel (UNS S31803) or Hastelloy stems provide superior corrosion resistance compared to standard 316L stainless steel.
