Numerical control electro-hydraulic valve is a valve controlled by an electromagnetic pilot valve, which drives the main valve piston to make arbitrary opening movements by the pressure of the medium itself. Through computer software control, it can achieve automatic control of the flow rate, flow rate, and pressure of the conveyed medium, and has functions such as constant current, constant pressure, and elimination of water hammer. It is a new type of CNC electro-hydraulic automatic control valve improved on the basis of diaphragm type electro-hydraulic valve. The valve body material includes cast aluminum, cast steel, all stainless steel, etc., with a wide range of applications. The reliability and operability of the product are superior to diaphragm type electro-hydraulic valves.

Tips for using CNC electro-hydraulic valves:

1. Prevent overload: Avoid using CNC electro-hydraulic valves for working conditions beyond their rated pressure and flow range. Overloading may cause the valve core to jam, seal to fail, or damage.

2. Electrical connection: According to the electrical wiring diagram of the CNC electro-hydraulic valve, correctly connect the power supply and control signal lines. Ensure reliable electrical connections and avoid misconnecting or reversing wires.

3. Operation control: Use correct operation methods and control signals, such as manual operation, automatic control, or remote control. Choose the appropriate control method according to actual needs.

4. Regular maintenance: Regularly inspect the working status of CNC electro-hydraulic valves, including sealing performance, electrical connections, wear of valve bodies and valves, etc. If there are any problems, timely maintenance and replacement should be carried out.

5. Preheating operation: Before starting the hydraulic system, perform appropriate preheating operation to gradually increase the temperature of the hydraulic oil and avoid damage to the CNC electro-hydraulic valve caused by sudden high temperature.

6. Discontinue storage: If the CNC electro-hydraulic valve is not used for a long time, it should be stored in a dry and clean environment to avoid dust and moisture from affecting it.

7. Prevent pollution: Keep the hydraulic system clean and prevent impurities and pollutants from entering the CNC electro-hydraulic valve. Use appropriate filters and filter cartridges, clean and replace them regularly.

8. Avoid frequent starting and stopping: Try to avoid frequent starting and stopping of hydraulic systems and CNC electro-hydraulic valves, as this can reduce wear on valve bodies and cores and extend their service life.

9. Correct installation: Install the CNC electro-hydraulic valve correctly according to the installation instructions. Ensure the correct connection between the valve body and the hydraulic system to prevent oil leakage and loosening.
