Actuation type influences seal loading and wear patterns in API 6A gate valves, whether manual, hydraulic, or pneumatic. Consistent, controlled actuation reduces impact loads on seals and seats, preventing chipping, localized compression set, and galling. Properly sized actuators ensure full travel to the seated position, so seals engage with correct contact stress for reliable shutoff. https://globalsealstech.com/product-category/oil-gas-seals/api-6a-gate-valve-seals/
