Hydraulic Pressure Controls Valves

In the hydraulic transmission system, the hydraulic valve that controls the oil pressure is called the pressure control valve, or the pressure valve for short. The common point of this type of valve is to use the principle of balance between the hydraulic pressure acting on the valve core and the spring force.The pressure control valve plays the role of pressure regulation and constant pressure in the system. It works on the principle that the control oil is in balance with the spring. Its working state is directly affected by the control pressure, and its state changes. To understand the structure of various pressure valves, it is convenient to grasp the working characteristics of the valve under different working conditions.In a specific hydraulic system, according to the work needs, the requirements for pressure control are different: some need to limit the maximum pressure of the hydraulic system, such as a safety valve; some need to stabilize the pressure value somewhere in the hydraulic system (or pressure difference, pressure ratio, etc.), such as relief valves, pressure reducing valves and other constant pressure valves; some use hydraulic pressure as a signal to control their actions, such as sequence valves, pressure relays, etc.
The function of the pressure control valve is to adjust and control the oil force in the hydraulic system. According to its function and purpose, it can be divided into relief valve, pressure reducing valve, sequence valve, pressure relay, etc. Their common characteristics are It works by the principle of balance between the hydraulic force acting on the valve core and the spring force. The stability of the pressure in the press depends on the stability of these hydraulic valves. If the hydraulic components are damaged or faulty, they must be repaired or replaced in time, because some minor faults cannot be handled properly, and if they are not timely, it will bring more damage
