WebSep 12, 2024 · The calculated breakaway valve force and torque were used as a basis for actuator air cylinder sizing assuming an air pressure of 7 barg and system efficiency of 90%. Additionally, force and torque for closing the valve were used to calculate the spring movement as well as spring piston length through Hook’s law. WebStatic friction is the friction when the two surfaces are sticking. The force required to overcome the static friction and initiate motion is called the breakaway force. The static friction is usually larger than Coulomb friction force. 2.2 Coulomb Friction Coulomb friction is independent of velocity and is always present.
