Currently, hydraulic valves can be categorized into many types based on different situations and applications. This article focuses on one type: the hydraulic valve. As an automated component operated by pressurized oil, the hydraulic valve is widely used in various industries such as construction machinery, sanitation equipment, and hydropower stations to control liquid pressure, flow rate, and direction. This type of hydraulic valve assembly consists of four parts: a cartridge valve, a control cover, a pilot control valve, and an integrated block, forming a two-way cartridge valve.
The cartridge valve can be considered a spool valve or cone valve. This component plays a crucial role in effectively controlling the flow direction, speed, and pressure of the oil in the channel or other areas. The control cover effectively controls the real-time operation of the cartridge valve, mainly because it contains many pilot control components. These components can adjust or control the operation of the cartridge valve. The control cover essentially acts as a bridge, connecting the control valve and the components, and the pilot control valve is also installed on it. Two-way cartridge valves are quite common in my country at present. From an economic point of view, they have fewer components and fewer necessary pipeline connections, making them easy to integrate and suitable for large-scale mass production, which can greatly reduce production costs.
