VICKERS hydraulic control valve DG4V-3S-2A-MUC560 from the United States
The function of VICKERS hydraulic control valve (referred to as hydraulic valve) in hydraulic systems is to control and regulate the flow direction, pressure, and flow rate of oil in the hydraulic system, so that the actuator and its driven working mechanism can obtain the required motion direction, thrust (torque), and motion speed (speed). Any hydraulic system, no matter how simple, cannot be without hydraulic valves; Hydraulic mechanical equipment with the same process purpose can form various hydraulic system schemes with completely different oil circuit structures through different combinations of hydraulic valves. Therefore, hydraulic valves are the most diverse, widely used, and active part (component) in hydraulic technology in terms of variety and specifications; Whether a newly designed or operating hydraulic system can operate normally and reliably according to established requirements largely depends on the performance and parameter matching of various hydraulic valves used in it

VICKERS hydraulic control valves are divided into relief valves, pressure reducing valves, and sequence valves according to their purposes. ① Overflow valve: It can control the hydraulic system to maintain a constant state when the set pressure is reached. The overflow valve used for overload protection is called a safety valve. When the system malfunctions and the pressure rises to a limit that may cause damage, the valve port will open and overflow to ensure the safety of the system. ② Pressure reducing valve: It can control the branch circuit to obtain a stable pressure lower than the main circuit oil pressure. Pressure reducing valves can be divided into fixed pressure reducing valves (with a constant output pressure), differential pressure reducing valves (with a constant input and output pressure difference), and proportional pressure reducing valves (with a certain ratio between input and output pressures) based on the pressure function they control. ③ Sequential valve: It can make one actuator (such as hydraulic cylinder, hydraulic motor, etc.) move and then make other actuators move in sequence

Introduction to VICKERS Hydraulic Control Valve
1. Working principle: According to the working principle and structure, pressure reducing valves are divided into two types: direct acting and pilot operated.
2. Function and performance requirements: The pressure reducing valve is used to reduce the pressure of a certain circuit in the system. A pressure reducing valve that reduces and maintains a constant outlet pressure is called a constant output pressure reducing valve; A pressure reducing valve that maintains a constant difference between its outlet pressure and a certain load pressure is called a differential pressure reducing valve; A pressure reducing valve that maintains a constant ratio of inlet pressure to outlet pressure is called a fixed ratio pressure reducing valve. The requirement for a constant output pressure reducing valve is that regardless of changes in inlet pressure, the outlet pressure should remain constant and not be affected by changes in flow rate through the valve. For differential or proportional pressure reducing valves, it is required to maintain a constant pressure difference or their ratio regardless of changes in inlet or outlet pressure.
3. Performance of pressure reducing valve: In addition to similar characteristics to relief valves, the following performance requirements are also required:
a. The change in outlet pressure caused by changes in inlet pressure is smaller. The larger the pressure difference between the inlet and outlet, the more stable the outlet pressure becomes when the inlet pressure changes;
b. The change in outlet pressure caused by the change in flow rate through the valve should be small;
c. For one-way pressure reducing valves, it is also required that the reverse pressure loss be small.
4. Selection of pressure reducing valve: When selecting a pressure reducing valve, it should be considered that the change trend of the opening and closing characteristics of the pressure reducing valve is opposite to that of the relief valve, that is, the secondary pressure decreases when the flow rate through the pressure reducing valve increases. Attention must be paid to the relationship between the set pressure of the pressure reducing valve and the working pressure of the actuator. Pilot operated pressure reducing valves have a greater oil release than other control valves. There is always oil flowing out of the pilot valve, which may be as high as 1L/min or more, affecting the selection of pump capacity. The adjustment range of secondary pressure depends on the spring used and the flow rate through the valve. The minimum adjustment pressure should ensure that the difference between the primary pressure and the secondary pressure is 0.3-1MPa. When the flow rate through the valve is much lower than the rated flow rate, it is prone to vibration or other unstable phenomena. At this point, measures should be taken on the circuit
