For businesses to understand the relationship between the price of electric butterfly valve and the market, we will be more easily determined how to do a good job in the overall production. To really determine the actual problems of these things is a guarantee for your purchase. The price is affected by the market. The market demand is large, but when there are few products, they are relatively expensive. But if there is less market demand and more products, the price is very cheap. Businesses should grasp this relationship to determine their own production quantity, not to produce too much, of course, not to produce too little.

Since the electric butterfly valve is composed of butterfly valve and electric equipment, how to select the electric equipment correctly after the electric butterfly valve is determined is an important factor related to whether the project demand can be satisfied in practical application. When selecting electric equipment, not only the above-mentioned working environment, electrical control and general skill functions should be considered, but also the inductive skill functions of electric butterfly valve equipment should be comprehensively considered.
1. Allowable value of valve stem diameter When selecting electric equipment, pay attention to the allowable valve stem diameter, and the valve stem diameter must be less than this value. In addition, the requirements for the height of the valve stem cover (related to the valve diameter) should also be put forward when selecting multi reversing electric equipment. Rotary stem valves may not be equipped with valve stem covers. Electric butterfly valve
2. Connection between valve and electric equipment Connection type and dimension of valve and electric equipment shall conform to national standards: connection of multi reversing valve driving equipment (GB/T12222-1989), connection of reversing valve driving equipment (GB/T12223-1989).
3. The output torque and speed output torque value of electric equipment is one of the important skill parameters of electric equipment, and also an important parameter to be selected in the application. If the output torque of the electric equipment selected when assembling the electric butterfly valve is too large or insufficient, it is not advisable. Due to the general situation, the electric equipment manufacturer needs to test and adjust the output torque value when the products leave the factory, which is relatively accurate. If excessive output torque margin is selected, the electric valve will have great potential danger. Once the operation and maintenance failure occurs, valve damage (valve stem twists, valve body cracks) will be easily formed, which is very easy to cause pipeline system accidents. Therefore, it is not advisable to select excessive output torque margin. If the valve cannot be opened in practice, it is also due to unreasonable selection.
