Abstract：The excellent performance of link butterfly valve makes it widely used in metallurgy， petrochemical， chemical， electric power and other industries. Through the analysis and calculation of the driving torque of link butterfly valve， the calculation formula of driving torque is obtained. According to the theoretical calculation， a more reasonable choice of driving device will give full play to its economic value.

Key words：link butterfly valve; four bar linkage; driving torque
