Same material, different lifespan. EPDM performance varies greatly. Its durability relies on formula, hardness, compression rate, groove geometry, medium and temperature. Long-term compression set and ageing resistance outweigh nominal single-point parameters.
Composite sealing becomes the new trend. Fillers, blending and surface coatings balance conflicting performance requirements. Sealing has evolved from individual components into multi-material, self-compensating structural systems.
Material iteration defines valve application boundaries. Every upgrade of sealing materials extends valves’operating range for temperature, pressure, corrosion and cyclic service, supporting extreme industrial working conditions.
Sealing evolves from accessory to core technology. The traditional design mindset that prioritizes valve body then selects seals is outdated. Sealing systems govern valve torque, tightness, service life and media compatibility.
Sealing details differentiate high-end valves. Valve bodies share similar construction. Product gaps hide in unseen sealing design: material grading, compound formula, compression ratio and groove precision.

Kerninzicht in de industrie. De evolutie van afdichtingsmaterialen stimuleert industriële vooruitgang. De toekomstige concurrentie in de klepindustrie ligt in de geoptimaliseerde afstemming van materiaal, structuur en bedrijfsomstandigheden, in plaats van eenvoudigweg dure premiummaterialen te specificeren.
