How should I select the filling valve for a viscous sauce filling machine?
• For viscosity >5000cP, choose a rotary pump with servo filling valve to avoid stringing.
• For particulate sauces, use a piston filling valve with bore ≥1.5x max particle size.
• For ±0.5% accuracy, select a servo-driven metering pump with weigh-feedback loop.
• Valve body in 316L; seals in EPDM or PTFE for acid and oil resistance.
• During trial, fill 100 consecutive bottles and verify CPK ≥1.33.
