Butterfly Valves for Molasses Service
Which butterfly valves configuration suits Molasses (C₁₂H₂₂O₁₁ (sucrose) + impurities), in which material, to which standard — from real service data, with the pitfalls flagged.
Which butterfly valves for Molasses?
Butterfly Valve (SS 316L, EPDM seat) - Molasses flow control on fermentation tanks and blending Typical service window: 1–8 barg (gravity/pump transfer), 25–80°C (heated for reduced viscosity in transfer).

Governing Standards for Molasses Service
ISO 9001:2015FSSAI (food-grade)ASME BPE (food/beverage hygienic design)ISO 14159 (hygiene requirements)
What to Avoid in Molasses Service
- Globe valves for high-viscosity molasses - excessive pressure drop
- Non-cleanable valves where CIP is required
Service Considerations
- Heat tracing or jacketing may be required to keep molasses pumpable in cold climates
- Full-bore valves essential - reduced-bore causes plugging with crystallised sugar
- CIP (clean-in-place) compatibility required where fermentation hygiene is critical
- High torque actuators needed - molasses viscosity creates high valve seating forces
