宝德先导阀 burkert 8803过程阀

 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, 虽然不需要考虑茎直径问题,但也应充分考虑当选择阀杆直径和键槽的尺寸,装配后正常工作。

Operating torque: operating burkert 8803torque is the most main parameter selection of valve electric actuator. 电动蝶阀运动过程可以由旅行或轴向推力的大小和转矩控制。由于阀门电动装置的工作特性和工作效率取决于阀门的类型,设备规范和阀门的管道或设备的位置, 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.
