Hydraulic valves are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. There are many kinds of hydraulic valves, different hydraulic valves play a role in different positions of the control system, commonly used check valves, safety valves, directional control valves, speed regulating valves, two-position two-way, two-position three-way, two-position four-way, two-position five-way, three-position five-way, as well as switching, central closed, central exhaust, central pressurized and other special functions of the hydraulic valve for different environments and actuating elements, hydraulic valves are controlled by the electromagnetic effect, the main control method by the relay control. The hydraulic valves are controlled by the effect of electromagnetism, and the main control method is controlled by relays.

The main features of hydraulic valve are as follows:

1, external leakage plugging, internal leakage is easy to control, the use of safety.

Internal and external leakage is an element that jeopardizes safety. Other self-control valves usually extend the valve stem, by electric, pneumatic, hydraulic actuators to control the rotation or movement of the spool. This is to solve the long-term action of the valve stem dynamic seal of the external leakage problem; hydraulic valve is electromagnetic force acting on the core sealed in the magnetic isolation casing to complete, there is no dynamic seal, so the external leakage is easy to plug. Electric valve torque control is not easy, easy to produce internal leakage, and even pull off the stem head; hydraulic valve structure type easy to control the internal leakage, until reduced to zero. Therefore, the use of hydraulic valves is particularly safe, especially for corrosive, toxic or high and low temperature media.

2, the system is simple, easy to connect to the computer, inexpensive.

Hydraulic valve itself is a simple structure, but also low, compared to other types of regulating valves and other types of actuators are easy to install and maintain. More is composed of automatic control system is much simpler, much lower. Because the hydraulic valve is switching signal control, and industrial control computer connection is very convenient. In today's computer popularity, a significant decline in the era, the hydraulic valve is more obvious.
