Hygienic DIN Metric Safety Valve (0.3 bar)
This specialized safety valve is designed for low-pressure protection in metric-standard systems. It comes with a complete DIN union set (liner, nut, and seal) for seamless integration into DIN 11851 piping. Factory-set at 0.3 bar, it is ideal for protecting thin-walled atmospheric tanks or fermenters from overpressure during filling or thermal expansion.
Standard: DIN metric sizing for global compatibility.
Safety: Pre-set 0.3 bar crack pressure for delicate vessels.
Hygiene: 316L stainless steel with a high-polish, crevice-free finish.
