Application scenarios and selection principles of multi-way valves
Multi-way valves are usually used in hydraulic systems.They can realize the connection and separation between different hydraulic components, thereby realizing the actions of different actuators. When selecting a multi-way valve, the following factors need to be considered:
1. Working pressure: The maximum working pressure of the multi-way valve needs to match the maximum working pressure of the hydraulic system, otherwise leakage and other problems will occur.
2. Flow: The maximum flow of the multi-way valve needs to match the flow of the hydraulic system, otherwise it will affect the working efficiency and even cause system failure.
3. Working medium: The multi-way valve needs to match the medium of the hydraulic system, otherwise it will affect the sealing performance and life of the valve.
4. Control method: The selection of the multi-way valve needs to be based on the control method of the hydraulic system, whether manual control or automatic control is required, etc.
5. Environmental conditions: The selection of the multi-way valve needs to consider factors such as ambient temperature, humidity, vibration, etc. to ensure the stability and life of the valve.

Method for matching the model of the multi-way valve
When matching the model of the multi-way valve, it is necessary to select a suitable valve model based on the above factors. Generally speaking, the model of a multi-way valve consists of the following parts:
1. Pressure level: indicates the maximum working pressure that the valve can withstand.
2. Flow level: indicates the maximum flow of the valve.
3. Connection diameter: indicates the connection diameter between the valve and the pipeline.
4. Control mode: indicates the control mode of the valve, manual or automatic.
5. Working medium: indicates the medium applicable to the valve.
2. Flow level: indicates the maximum flow of the valve.
3. Connection diameter: indicates the connection diameter between the valve and the pipeline.
4. Control mode: indicates the control mode of the valve, manual or automatic.
5. Working medium: indicates the medium applicable to the valve.
When matching the model of a multi-way valve, it is necessary to select a suitable model according to the actual situation, and compare the product performance and price of different manufacturers, and finally select the product with the highest cost performance.
