As an indispensable key component in the industrial field, valves have a long history of development. Since the beginning of the 20th century, valve technology has undergone continuous evolution and innovation. In the early days, simple mechanical valves were mainly used for basic fluid control. With the development of industry, the performance and functional requirements of valves have been increasing. Different eras have witnessed the emergence of various valve products, from traditional manual valves to increasingly automated electric and pneumatic valves. Each innovation is aimed at meeting the needs of more complex industrial processes. These valve products are not only continuously optimized in structure, but also have made significant progress in material selection, sealing performance, etc., to adapt to various harsh working environments and media requirements.
Valve Control have many significant characteristics. Its structural design is exquisite, and different types of valves have their own advantages. For example, some valves have the characteristics of large flow capacity, which can efficiently transport a large amount of media per unit time to ensure the smooth progress of the process. At the same time, the valve has a small imbalance, which makes it possible to more stably control the pressure and flow of the fluid during operation, reducing fluctuations and errors. In addition, operational stability is also one of its important advantages. Whether it is manually operated or in conjunction with an automated control system, the valve can be opened, closed and adjusted accurately and reliably, providing a solid guarantee for industrial production.
The flow characteristics of the valve are crucial for accurately controlling the flow of the medium. Valve Control valves have three flow characteristics: linear, equal percentage and parabolic. The linear flow characteristic means that there is a linear relationship between the valve opening and the flow rate. It has advantages in some occasions where the flow change is required to be relatively uniform, and can intuitively achieve linear flow regulation. The equal percentage flow characteristic means that as the valve opening increases, the relative change in flow rate increases by an equal percentage. This characteristic can better meet the system's requirements for flow regulation accuracy when the flow change range is large, making the entire regulation process more stable and accurate. The parabolic flow characteristic combines the characteristics of linear and equal percentage, and can provide a more ideal flow control effect under certain special conditions, providing a variety of choices for complex industrial processes.
Valve Controls play a vital role in the field of industrial automation process control. It can accurately adjust the process parameters such as flow, pressure, temperature, liquid level, etc. of the medium, thereby ensuring the stable operation and optimized control of the entire production process.
