Valve Selection
Valve Calculations
Valve calculations turn service conditions into engineering numbers: flow coefficient, torque, pressure drop, actuator force, and sizing are all part of specifying a valve correctly. This tag collects articles on flow coefficient and its application, handwheel torque and gearbox calculations, actuator force requirements, and pressure-drop and velocity considerations for piping systems. Content walks through worked examples and practical formulas for selecting and verifying valves, with emphasis on getting the inputs right. Written for engineers who need calculation guidance they can apply directly to their projects.
