   he role of hydraulic valves

The hydraulic valve is used to control the flow direction of the oil in the hydraulic system or to adjust its pressure and flow, so it can be divided into direction valves, pressure valves and flow valves
Three broad categories. A valve with the same shape can have different functions because of the different mechanism of action. The pressure valve and the flow valve use the flow section
The throttling action controls the pressure and flow of the system, while the direction valve controls the flow direction of the oil by changing the flow channel. That is to say, though
There are a variety of different types of hydraulic valves, and they still maintain some basic points in common. For example:
(1) Structurally, all valves are composed of a valve body, a spool (rotary valve or slide valve), and elements and components (such as springs and electromagnets) that drive the spool action.
(2) In terms of working principle, the relationship between the opening size of all valves, the pressure difference between the inlet and outlet of the valve and the flow through the valve is in line with the orifice flow
Only the parameters of various valve control are different.

   Hydraulic valve is an automatic component operated with pressure oil, it is controlled by pressure valve pressure oil, usually combined with electromagnetic pressure valve, can be used for remote control of hydropower station oil, gas, water pipeline system. Commonly used for clamping, control, lubrication and other oil circuit. There are direct action type and pioneer type, multi-use pioneer type. The role of the hydraulic valve is mainly used to reduce and stabilize the oil pressure of a branch in the system, and it is often used for clamping, controlling, lubricating and other oil circuits. There are direct moving type, leading type and superposition type. A component used in hydraulic transmission to control the pressure, flow, and direction of liquids. The pressure control valve is called the pressure control valve, the flow control valve is called the flow control valve, and the control on, off and flow direction is called the direction control valve. Classification of hydraulic valves: classification by function: flow valve (throttle valve, speed regulating valve, diverter valve, collecting valve, diverter collecting valve), pressure valve (relief valve, pressure reducing valve, sequence valve, unloading valve), direction valve (electromagnetic reversing valve, manual reversing valve, check valve, hydraulic control check valve)
