The SVL606 is suitable for the overpressure protection of steam

boilers, pipelines, pressure vessels and most general process

industry applications, particularly where a valve of all stainless steel

construction is required to minimise contamination of the process

media or where hygienic considerations and aesthetic qualities are

prerequisites. This valve is also suitable for cryogenic service.
