STERI-TROL clean service control valve
Spirax Sarco STERI-TROL clean service control valves combine hygienic design, drainability and modulating or on-off control for clean steam and clean process duties.
Quick facts
STERI-TROL is aimed at duties where the valve has to do more than isolate or reduce pressure. It is better suited to applications that need repeatable modulation, automated positioning or diverting control while still meeting the drainability and cleanability expectations of hygienic process lines.
That makes it relevant on systems where control stability and hygienic valve design have to be solved together, rather than by adapting a general industrial control valve into a clean-service environment later.
Clean-service control valves usually sit inside a wider hygienic package that also depends on generation, pressure control, drainage and documentation requirements.
Return to the wider clean steam range when control-valve selection is only one part of a broader hygienic steam or clean-fluid package.
Use sanitary pressure reducing valves when the duty depends on self-acting local pressure reduction rather than a pneumatically actuated control valve.
Move into clean steam generation when the clean-service valve is being specified downstream of a dedicated hygienic steam source.
