 burkert 8803Stem diameter: for multi-turn rising stem valves, cannot assemble into electric valve. Therefore, if the electric butterfly valve device allows maximum stem diameter can't through the stem of the valve, the inner diameter of the hollow output shaft of electric device must be greater than rising stem valves stem diameter. In local rotary valve and multi-turn valves non-rising stem valves, 雖然不需要考慮莖直徑問題,但也應充分考慮當選擇閥桿直徑和鍵槽的尺寸,裝配后正常工作。

Operating torque: operating burkert 8803torque is the most main parameter selection of valve electric actuator. 電動蝶閥運動過程可以由旅行或軸向推力的大小和轉矩控制。由于閥門電動裝置的工作特性和工作效率取決于閥門的類型,設備規(guī)范和閥門的管道或設備的位置, electric butterfly valve device is programmable valve, burkert 8803control valve and remote control of the indispensable equipment. Therefore, the correct selection of valve electric device, to prevent overload phenomenon (work torque is higher than the control torque) burkert 8803is very important. Usually, the basis of correct selection of valve electric butterfly valve.
