Thermal expansion considerations in API 6A Gate Valve Seals ensure proper sealing across wide temperature ranges. Material thermal expansion coefficients match valve body materials preventing seal compression or relaxation issues. Design features accommodate dimensional changes during temperature cycling. Our thermally-optimized seals maintain contact pressure and sealing effectivenes... https://globalsealstech.com/product-category/oil-gas-seals/api-6a-gate-valve-seals/
