The selection of the valve actuation method is based on: 1) the type, specifications, and structure of the valve. 2) Opening and closing torque of the valve (pipeline pressure, maximum pressure difference of the valve), thrust. 3) Maximum ambient temperature and fluid temperature. 4) Usage method and number of uses. 5) Opening and closing speed and time. 6) Valve stem diameter, pitch, rotation direction. 7) Connection method. 8) Power source parameters: voltage, number of phases, and frequency for electric power sources ； Pneumatic supply pressure ； The pressure of the hydraulic source in a hydraulic system. 9) Special considerations: low temperature, corrosion resistance, explosion protection, water resistance, fire resistance, radiation protection, etc.
