Gate valve seals utilize various cross-sectional profiles including O-rings, T-seals, U-cups, and custom geometries. O-rings provide simple, cost-effective sealing for moderate pressure applications. T-seals offer enhanced pressure resistance through their asymmetric design. U-cup configurations excel in dynamic applications where the gate moves frequently. Custom profiles address uni... https://globalsealstech.com/product-category/oil-gas-seals/api-6a-gate-valve-seals/
