SVL488 clean service safety valve for hygienic overpressure protection
Spirax Sarco SVL488 clean service safety valves provide hygienic overpressure protection for pure steam, clean steam and inert gas systems used in clean-service applications.
Quick facts
Clean-service systems still need the same disciplined overpressure protection as any other pressure installation. The difference is that the relief device also has to fit high-purity media, sanitary pipework and the wider validation expectations around the protected package. SVL488 addresses that protection role for pure steam, clean steam and inert gas duties.
In practice, this makes the valve relevant wherever a hygienic package has to combine pressure relief performance with material suitability and cleaner-system expectations, not just satisfy a generic overpressure checklist.
Safety valve duties are usually tied to the wider clean steam arrangement, especially where generation, pressure reduction and vessel protection interact.

Review sanitary pressure reducing valves when downstream pressure control and overpressure protection need to be specified together.
Use clean steam generators when hygienic overpressure protection is part of a dedicated clean steam generation package.
