READ MOREPrecautions for using 4WE6 high-pressure solenoid directional valve
Precautions for using the 4WE6 high-pressure solenoid reversing valve are as follows: Preparation before installation: Model verification: Before installation, the model and specifications of the solenoid valve need to be carefully checked to ensure that they are consistent with the system design requirements, including working pressure, flow, voltage and other parameters. Appearance inspection: Check whether there is any damage to the appearance of the solenoid valve, such as cracked shell, damaged coil, etc., to ensure that the solenoid valve is intact. Pipe cleaning: Clean the inside of the pipe connecting the solenoid valve to remove impurities, rust, welding slag and other foreign matter to prevent impurities from entering the solenoid valve and causing the valve core to jam or seal loosely. Installation location selection: Choose a dry, well-ventilated location that is convenient for operation and maintenance to install the solenoid valve. Avoid installing it in places with strong vibration, impact, or close to heat sources. Precautions during the installation process: Installation direction: Install strictly according to the fluid flow direction marked on the solenoid valve shell, ensuring that the medium flows in from the inlet end and flows out from the outlet end. Wrong installation direction may cause the solenoid valve to fail.

The service life of the 4WEH16 electro-hydraulic reversing valve has no fixed number of years, but it mainly depends on the working life of the electromagnet. The service life of the DC electromagnet is usually more than ten million times, and the service life of the AC electromagnet is between hundreds of thousands to millions of times. Specifically, the service life of the 4WEH16 electro-hydraulic reversing valve is affected by the following factors: Electromagnet type: DC electromagnet: It has a long service life, generally more than 10 million times, and some even up to 40 million times. AC electromagnets: Relatively short service life, typically between hundreds of thousands to millions of operations. Working environment: In harsh working environments, such as high temperature, high humidity, corrosive gases or places with a lot of dust, the wear of electromagnets and other components will increase, thus shortening the service life. Frequency of use: High-frequency commutation operations will accelerate the fatigue of electromagnets and other components, resulting in shortened service life. Maintenance: Regular maintenance can extend the service life of the electro-hydraulic reversing valve.

READ MOREInstallation sequence of superimposed hydraulic control check valve
The installation sequence and key points of the superimposed hydraulic control check valve are as follows: 1. Installation sequence The hydraulic control check valve installed on the bottom layer must be used as the bottom valve body and installed close to the foundation plate. This is to ensure the normal pressure-holding function and prevent pressure-holding failure due to improper installation position. Stacking Sequence In hydraulic systems, the installation sequence of stacking valves usually follows functional requirements. The typical sequence is: basic base plate → hydraulic control check valve (bottom layer) → pressure reducing valve/pressure valve → directional valve (such as solenoid reversing valve) → flow valve (throttle valve, etc.) → actuator connecting plate. If the system includes an externally controlled pressure reducing valve and a one-way throttle valve, the one-way throttle valve must be located between the externally controlled pressure reducing valve and the hydraulic cylinder; if used together with a hydraulically controlled one-way valve, the hydraulically controlled one-way valve must be located between the externally controlled pressure reducing valve and the hydraulic cylinder. Alignment of oil holes Before installation, it is necessary to confirm that the position of the oil holes of the superimposed valve is correct, and align all screw mounting holes to ensure smooth oil passage. The bolts are fixed with grade 12.9 high strength
