Power drive of pneumatic butterfly valve
The pneumatic butterfly valve is directly connected to the 22V or 380V power supply, and the switching action is completed through positive and negative direction switching; The regulated pneumatic butterfly valve is driven by 220 V power supply and receives the preset parameter value information of the industrial automation control system to complete the regulation action. Compared with other control valve products, electric control valve also has some disadvantages, because it is assembled by electric actuator and control valve, resulting in relatively poor sealing performance of electric control valve. In addition, its operating pressure and temperature range are limited. In a very small range.
At present, valve enterprises should adhere to product development, product improvement and strive to develop towards high-end valves. Some large companies should take the lead in learning foreign valves and try to use domestic valves. Some small enterprises must do a good job in production, strengthen management, strengthen night technology and tooling, and improve product quality, grade and competitiveness.
With the continuous development and change of the industry, the demand for products will be different. We must be very clear that only by improving the quality of our products can we gain more recognition. Therefore, we must stand up and do a good job in relevant cognitive work, so that the overall quality can reach a certain level and be recognized by more people, so as to have more advantages in the competition.
