The hydraulic valve is a kind of automatic element which is operated by the pressure oil, it is controlled by the pressure oil of the distribution valve, commonly used in combination with electromagnetic pressure valve, can be used for long-distance control of the power station oil, gas, water pipe system of the break. Commonly used in clamping, control, lubrication and other circuit. There are direct and pilot type of the division, more use of the pilot type.

The hydraulic valve is used to control the flow direction of oil in the hydraulic system or to regulate its pressure and flow, so it can be divided into three categories: directional valve, Hydraulic Valves pressure valve and flow valve. A different shapes of the same valve can be caused by the mechanism and have different functions. pressure valves and flow valves control the pressure and flow of the system using the throttling effect of the flow cross-section, while the directional valve controls the flow direction of the fluid by means of the change of the flow path. That is to say, although there are various types of hydraulic valves, Hydraulic Valves They still maintain some of the basic common points.

Hydraulic valves are commonly used in industry as an automatic component of pressure control, the hydraulic valve works mainly by the internal pressure oil control, may through with the pressure valve's cooperation to carry on the comparison long-distance water and electricity pipeline control, at present the market commonly has two kinds mainly, the direct movement type and the forerunner type.

Hydraulic valve is mainly used to control the hydraulic system of liquid pressure and flow, in the hydraulic valve control can be the pressure and flow direction to make more accurate control. What is the working principle of the hydraulic valve? Mainly through the programmable control system to make the central link of the equipment, in the operation of the time is carried out through the program to operate, Hydraulic Valves in the use of PLC data can be changed to achieve better control effect.

Hydraulic valve Working principle is mainly used in the electrical operation and the implementation of components, in the work can play a good stability, for different customer needs can carry out supporting workpiece control, for equipment working parameters can also be extended arbitrarily to meet the requirements of a more than one machine. The equipment can quickly eliminate some faults through the perfect self diagnosis system, Hydraulic Valves especially through the display of dynamic waveform, which can quickly analyze the error of workpiece dimension and the Burr defect on the surface.

What are the features of the hydraulic valve?

First, the efficient electromagnetic action can be achieved. The built-in push rod can quickly play a buffer effect, under the action of high pressure can still ensure a smooth and silent operation, and the device is equipped with a sliding core, can quickly eliminate the friction between the putter due to the leakage of oil.

Second, the valve body of the hydraulic valve most uses is the special design, may let the internal resistance be smaller, thus enables the energy to obtain the efficient utilization, Hydraulic Valves and now the energy saving idea is very consistent, therefore receives the more people the esteem.

Third, the hydraulic valve can be controlled by the oil temperature to reduce the equipment failure, thus saving most of the maintenance costs, because the internal temperature through the intelligent system control in a reliable range, so not because the heat is too high to appear processing accuracy errors.

The hydraulic valve is also very convenient to install, most of the screws are fixed in the way the problem can be quickly disassembled, equipment inside the electrical wiring reserved space is relatively large, Hydraulic Valves can be more testing and wiring, the junction also carried out a waterproof and dustproof treatment can ensure the long-term use of equipment without fault.
