Component Specifications

Definition
A precision-engineered sealing component designed specifically for sanitary flow control valves in food and beverage processing applications. It creates a leak-proof barrier between valve components while maintaining strict hygienic standards, preventing contamination and ensuring product purity during fluid transfer operations.
Working Principle
The gasket operates on compression sealing principles, where controlled deformation under bolt torque creates a tight seal between mating surfaces. It fills microscopic imperfections in flange faces, preventing fluid leakage while withstanding pressure differentials, temperature variations, and mechanical stresses during valve operation.
Materials
FDA-compliant EPDM (Ethylene Propylene Diene Monomer) rubber with food-grade certifications, Shore A hardness 70±5, temperature range -40°C to +150°C, resistant to steam, cleaning chemicals, and food products
Technical Parameters
  • Color White (FDA compliant)
  • Diameter DN25-DN150
  • Thickness 3mm ±0.2mm
  • Surface Finish Ra ≤ 0.8 μm
  • Pressure Rating 16 bar maximum
  • Temperature Range -40°C to +150°C
Standards
ISO 2852, DIN 11864-1, 3-A Sanitary Standards 72-03

Frequently Asked Questions

What cleaning methods are suitable for this gasket?

The EPDM material withstands CIP (Clean-in-Place) procedures with hot water, steam, and food-grade sanitizers like peracetic acid or hydrogen peroxide solutions.

How often should sanitary gaskets be replaced?

Recommended replacement every 6-12 months or immediately if visible damage, compression set exceeds 15%, or leakage occurs despite proper torque.

Can this gasket handle both liquid and gas applications?

Yes, it provides effective sealing for both liquid food products and cleaning/sanitizing gases including steam up to 150°C.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
