BY SERVICE MEDIUM
Hygienic / Sanitary Valves
Liquid, gas, steam or slurry names used by buyers. The node is a route, not a corrosion allowance.
Choosing Hygienic / Sanitary Valves
Hygienic and sanitary service adds cleanability and contamination-control requirements to ordinary pressure and flow selection. Drainability, surface condition, seal design and cleaning cycles must match the process. A polished exterior does not establish internal hygienic design.
What to include in the RFQ
- Specify product fluid, cleaning/sterilization cycle and installation orientation.
- Request wetted materials, surface finish, drainability and seal documentation.
- For separated streams, identify leakage detection and the required mixing/changeover behavior.
Selection scenario
At a product/cleaning interface, show which streams must remain separated in each operating position. Review the valve internals and cleaning sequence before selecting a mixproof or diaphragm arrangement.
Common selection mismatch
Food, sanitary and aseptic are not interchangeable qualifications. Request the evidence required by the actual process and offered design.
