Torque Value of Single Eccentric Butterfly Valve

The Torque Value of Single Eccentric Butterfly Valve is calculated based on normal temperature and clean medium.

The specific calculation method is one-half of the square of the single eccentric butterfly valve diameter x3.14 gets the area of the valve plate, and then multiplies it by the pressure to get the static pressure on the shaft. Multiply by the friction coefficient, multiply by the shaft diameter and divide by 1000 to get the torque.
