Torque requirements for ball valve actuation increase with seal friction, which varies with temperature, pressure, seal material, and lubrication. LNG service may experience higher breakaway torque at cryogenic temperatures where seals become stiffer, requiring actuator sizing to accommodate worst-case torque conditions while avoiding seal damage from excessive forces. https://globalsealstech.com/product-category/oil-gas-seals/api-6d-ball-valve-and-lng-seals/
