Hydraulic valves are components used to control the fluid flow in a hydraulic system, and they have the following main performance characteristics:
- **Pressure control performance**:
It can precisely control the pressure in the hydraulic system. By adjusting the opening degree of the valve, the system pressure can be stabilized within the set value range, preventing damage to the system caused by excessive pressure or ensuring that the actuator cannot work properly due to too low pressure. For example, in the hydraulic systems of some large mechanical equipment, hydraulic valves can ensure that the system pressure always meets the working requirements of the equipment, whether it is running under no-load or full-load conditions.
- **Flow control performance**:
It can accurately regulate the flow rate of the fluid. According to the needs of the system, the flow area of the valve can be flexibly changed, thus controlling the flow rate of the hydraulic oil and further controlling the moving speed of the actuator. For instance, in the hydraulic transmission system of a machine tool, precisely controlling the flow rate through hydraulic valves can achieve different feed speeds of components such as the worktable to meet various machining process requirements.
- **Response speed**:
Hydraulic valves usually have a fast response speed. They can react to changes in the system's pressure, flow rate, etc. within a short time and quickly adjust the opening degree of the valve to meet the dynamic performance requirements of the system. In some hydraulic systems that require rapid action, such as the hydraulic actuation systems in the aerospace field, the fast response of hydraulic valves can ensure that control mechanisms such as the aircraft's control surfaces move quickly, guaranteeing the stability and maneuverability of flight.
- **Sealing performance**:
They have good sealing performance. They can effectively prevent the leakage of hydraulic oil, ensuring the working efficiency and stability of the system. Good sealing performance can avoid problems such as pressure loss and insufficient flow rate caused by leakage. At the same time, it can also prevent hydraulic oil from polluting the environment. For example, in some high-precision hydraulic control systems, even a tiny leakage may affect the accuracy and reliability of the system. Therefore, the sealing performance of hydraulic valves is of vital importance.
- **Reliability**:
With high design and manufacturing quality, they have high reliability and stability. They can operate stably for a long time under harsh working environments and withstand high pressure and frequent action cycles. In various hydraulic equipment in industrial production, such as injection molding machines and die-casting machines, hydraulic valves need to work continuously for a long time, and their reliability directly affects the smooth progress of the entire production process.
