定义
The Seat/Seal Ring is a precision-engineered sealing element within aseptic filling valve assemblies, designed to create a hermetic seal between moving parts during filling operations. It prevents microbial ingress, maintains sterility of the product stream, and controls fluid flow with minimal particulate generation in hygienic processing environments.
工作原理
Operates through elastic deformation under controlled compression to form a leak-tight barrier between valve seat surfaces, preventing fluid escape and external contamination while allowing precise valve actuation.
材料

ID
8-35 mm
OD
15-50 mm
Thickness
2-6 mm
Surface Finish
Ra ≤ 0.8 μm
Pressure Rating

常见问题

How often should Seat/Seal Rings be replaced in aseptic filling systems?

Replacement intervals depend on operational cycles and CIP/SIP frequency, typically every 3-6 months or 10,000-50,000 cycles. Regular inspection for compression set, cracks, or surface degradation is recommended.

What material is best for Seat/Seal Rings in acidic beverage applications?

FKM/Viton offers superior chemical resistance for acidic products, while EPDM is suitable for alkaline environments. Material selection must consider pH, temperature, and cleaning agents.
