Component Specifications

Definition
A precision-engineered sealing element designed specifically for filling valve assemblies in beverage manufacturing equipment. This component creates a hermetic seal between moving parts of the valve mechanism, preventing product contamination, maintaining pressure integrity, and ensuring accurate volumetric filling. It withstands repeated compression cycles, chemical exposure to various beverages, and sterilization processes while maintaining dimensional stability and sealing performance.
Working Principle
Operates through controlled compression between mating surfaces of the filling valve. When the valve closes, the sealing element deforms elastically to fill microscopic surface imperfections, creating a barrier against fluid passage. The seal maintains constant contact pressure through spring-back properties, adapting to thermal expansion and mechanical wear while preventing both leakage and product ingress into valve mechanisms.
Materials
Food-grade elastomers (typically EPDM, silicone, or fluorocarbon compounds) meeting FDA 21 CFR 177.2600 and EU 10/2011 regulations. Material specifications include: Shore A hardness 60-80, temperature resistance -40°C to 180°C, chemical resistance to acids, alkalis, and cleaning agents, low compression set (<15% after 24h at 70°C), and non-toxic, non-tainting formulation.
Technical Parameters
  • Surface Finish Ra 0.8 μm max
  • Compression Set <20%
  • Life Expectancy >1 million cycles
  • Temperature Range -20°C to 140°C
  • Operating Pressure 0-10 bar
  • Dimensional Tolerance ±0.1 mm
  • Chemical Compatibility pH 2-12
Standards
ISO 3601-1, DIN 3771, FDA 21 CFR 177.2600, EU 10/2011

Frequently Asked Questions

How often should sealing elements be replaced in filling valves?

Replacement intervals depend on operating conditions, but typically range from 3-12 months. Factors include cycle frequency, product characteristics, cleaning chemical exposure, and visual inspection for wear, compression set, or surface degradation.

Can the same sealing element be used for different beverage types?

Material compatibility must be verified for each application. While many food-grade elastomers handle multiple products, specific formulations may be required for carbonated beverages, acidic juices, alcoholic products, or hot-fill applications to prevent swelling, degradation, or flavor transfer.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
