What material should a diaphragm valve for Glycerine / Glycerol (C₃H₈O₃) be?

SS 316L (Excellent): Preferred for pharmaceutical and food-grade glycerine. PTFE seals (Excellent): Best for pharmaceutical glycerine - no extract, USP VI compliant. Carbon Steel (Good): Acceptable for industrial glycerine (non-pharma). Bronze/Brass (Good): Traditional material for glycerine utility valves. EPDM seals (Good): Acceptable for food/cosmetic grade glycerine.

What to Avoid in Glycerine / Glycerol (C₃H₈O₃) Service

Reduced-bore valves for high-viscosity glycerine - excessive pressure drop

Service Considerations

Heat glycerine to 60°C to reduce viscosity for pumping - all transfer lines may need heat tracing
Pharmaceutical grade: ASME BPE compliant valves, Ra ≤0.8 µm internal surface finish
CIP/SIP compatible design required for pharmaceutical glycerine
Biodiesel plant crude glycerine: methanol residue may be present - check compatibility
