Seal Ring Component – Food Manufacturing

Component Specifications

Definition

A specialized sealing ring designed to maintain pressure integrity in starch slurry control valves, preventing leakage of viscous food-grade slurries while withstanding pressure fluctuations and abrasive particulate content typical in starch processing applications.

Working Principle

Creates a static or dynamic seal between valve components through elastic deformation under compression, preventing slurry leakage while allowing controlled pressure regulation through the valve assembly.

Materials

Food-grade EPDM rubber (Ethylene Propylene Diene Monomer) with FDA 21 CFR 177.2600 compliance, Shore A hardness 70±5, temperature range -40°C to +150°C, resistant to starch enzymes and cleaning chemicals.

Technical Parameters

Cross-Section 3.53 mm
Inner Diameter 25.4 mm
Surface Finish Ra ≤ 0.8 μm
Compression Set ≤15% (22h at 100°C)
Temperature Range -40°C to +150°C
Operating Pressure 0-10 bar

Standards

ISO 3601-1, DIN 3771, FDA 21 CFR 177.2600

Frequently Asked Questions

Why is EPDM the preferred material for starch slurry seal rings?

EPDM offers excellent resistance to starch enzymes, hot water, and cleaning chemicals while maintaining flexibility across temperature variations common in food processing.

How often should starch slurry valve seal rings be replaced?

Typically every 6-12 months depending on operating cycles, but inspect quarterly for wear, compression set, or surface degradation.

Can these seal rings handle abrasive starch particles?

Yes, the specified EPDM formulation includes additives for abrasion resistance, but proper filtration upstream is recommended to extend service life.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
