What are the common points of hydraulic valves

Although there are different types of hydraulic valves, they still have the following common features

1. In the structure; all hydraulic valves are composed of valve core, valve body and components that drive the valve body to move the valve body firstly.

2. In principle, all hydraulic valves use the relative movement of the valve plug in the valve body to control the opening and closing of the valve port and limit or change the flow and stop of the oil.

3. As long as there is also flow through the valve hole, pressure drop and temperature increase will occur. The flow through the valve orifice is related to the flow area and the pressure difference between the valve and the valve.

4. In terms of function; the valve can not do work outside, just to meet the requirements of the actuator pressure, speed and commutation.

5. In terms of parameters, one is the specification parameter, which indicates the size of the valve and the scope of its use. It is generally expressed by the nominal pass. The size of the through-flow capacity of the nominal valve representing the valve corresponds to the rated flow of the valve. The specifications of the tubing linked with the inlet and outlet of the valve shall be matched with the passage of the valve; but the performance parameter represents the functional characteristics of the valve, such as Rated pressure, it is the high working pressure allowed by normal operation of hydraulic valve/news_show_141.html
