What is the role of proportional directional control valve in hydraulic system?
Proportional directional valve is a very important part of the hydraulic system. Its main function is to control the direction and speed of fluid flow to achieve control of specific tasks. So, what is the role of the proportional directional control valve in the hydraulic system? In this article, we will discuss in detail the working principle, advantages and applications of proportional directional valves in hydraulic systems.
Working principle:
The proportional directional valve changes the flow direction and speed of the fluid by controlling the movement of the valve core. When the spool moves in one direction, fluid flows from one position to another. It regulates the pressure and flow of fluid to meet the needs of the system. In addition, proportional directional valves can control the flow rate of fluid as needed, making them suitable for different tasks.
Advantage:
1. High precision
Proportional directional valves can control the flow rate and flow rate of fluid, allowing the hydraulic system to perform tasks more accurately. It can control the flow rate of fluid to a few decimal places, making it ideal for applications that require high-precision control.
2. Fast response
The proportional directional valve responds very quickly because it controls the flow rate of the fluid according to the needs of the system. When tasks such as acceleration or braking are required, proportional directional valves can quickly respond and adjust fluid flow, making the system more flexible and efficient.
Application:
Proportional directional valves are suitable for use in a variety of hydraulic systems, including presses, injection molding machines, excavators, milling machines and lathes. They are widely used in various industries such as manufacturing, construction, agriculture, etc. In these industries, proportional directional valves are used to control a variety of tasks, such as controlling accelerators, hydraulic cylinders, steering systems, and braking systems. They are also widely used in the automation industry, such as controlling material flow on assembly lines.
Summarize:
The proportional directional valve is a key component in the hydraulic system, which can control the direction and speed of fluid flow. With its high precision and fast response characteristics, it is widely used in various industries and equipment, allowing hydraulic systems to operate more efficiently and flexibly. If you are considering improving the control of your hydraulic system, a proportional directional valve is a recommended choice.
