Shanghai Nuoyou Valve Industry Valve Torque Calculation and Butterfly Valve Torque Table

Time: 2016-03-24Source : Shanghai Nuoyou Valve Industry Co., Ltd.
Shanghai Nuoyou Valve Industry The valve torque calculation and butterfly valve torque meter valves are divided into two types: pneumatic valves and electric valves. The main types of sales are also pneumatic and electric. The main difference between pneumatic valves and electric valves is the difference in actuators. Electric actuators are more complex than pneumatic actuators. The key to the selection of pneumatic and electric actuators is the torque. The value of the valve torque determines the actuator.

Torque refers to the rotational force required to operate the valve. The maximum value of this required rotational force is the selection element of the actuator. The calculation of this value usually comes from the friction of the bearing and the seat / valve of a certain tooth The sum of the torque produced by the flap interference friction. Due to the uncertain factors of friction, the calculation of torque is more complicated, and the values are different. The following is a partial torque value of our factory butterfly valve for reference and comparison
