Hygienic DIN Vacuum Valve (50mbar)
This safety valve is designed to prevent tank collapse by breaking vacuum during rapid cooling or emptying. Pre-set at 50mbar, it opens to allow filtered air into the vessel when internal pressure drops. The DIN 11851 union set ensures a hygienic, leak-proof connection to metric piping systems.
Protection: Essential for thin-walled tanks prone to implosion.
Standards: Metric DIN sizing for European process lines.
Cleanliness: 316L stainless steel, fully CIP-compatible.
