Butterfly Valve Sealing Rings
Seals for Food and Sanitary Pipeline Systems
These are butterfly valve sealing rings, specifically engineered for food and sanitary pipeline systems—critical for sectors requiring strict hygiene standards. They create a robust seal at butterfly valve connections, effectively blocking fluid leakage to maintain pipeline integrity during medium transport.
Crafted to enhance system reliability, they minimize operational disruptions caused by leaks, boosting overall efficiency. Their design aligns with food-grade and sanitary requirements, ensuring compliance while delivering long-lasting sealing performance, making them a trustworthy choice for fluid control applications.

1. Product Advantages
Forever Seals butterfly valve sealing rings stand out with food-grade & sanitary-grade materials, complying with strict industry standards to ensure no contamination to transported media. They feature exceptional wear resistance and aging resistance, extending service life by 30% compared to ordinary seals. The high elasticity design enables tight fitting with valve connections, achieving zero fluid leakage and reducing maintenance costs for pipeline systems.
2. Working Principle
The sealing ring is installed between the butterfly valve’s valve body and disc. When the valve is closed, the ring is compressed by the disc, deforming slightly to fill tiny gaps at the connection. This deformation creates a reliable sealing interface, blocking the flow of liquids or gases. When the valve opens, the ring rebounds to its original shape, ready for the next sealing cycle—ensuring consistent performance in repeated opening and closing operations.
3. Product Details
Material: Food-safe rubber (FDA-certified) or silicone, non-toxic, odorless, and resistant to corrosion from weak acids/alkalis.
Dimensions: Customizable to fit various butterfly valve sizes (DN50-DN600), with precise tolerance control (±0.1mm) for perfect compatibility.
Surface Finish: Smooth surface to avoid media residue, easy to clean, and suitable for frequent sanitation in food processing scenarios.
4. Application Range
Widely used in food & beverage industry (e.g., milk, juice, beer pipelines), pharmaceutical industry (drug solution transport), cosmetics industry (raw material pipelines), and other sectors requiring high sanitary standards. It is also applicable to water treatment systems that demand leak-proof and non-polluting seals.
5. FAQ
Q: Can the sealing ring withstand high temperatures?
A: Yes, our high-temperature resistant version can endure 120°C (248°F), suitable for hot media transport like pasteurization pipelines.
Q: How often should the seal be replaced?
A: Under normal use (8 hours/day, 5 days/week), it can last 18-24 months—longer than most competitors’products.
