READ MORE4What is the service life of the WEH16 electro-hydraulic reversing valve?
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

READ MOREMaintenance method of single-head solenoid reversing valve
Maintenance of single-head solenoid reversing valves requires daily inspections, regular cleaning, lubrication and maintenance, troubleshooting, installation specifications, environmental control, professional maintenance, etc. The specific methods are as follows: 1. Routine power supply inspection: Regularly check whether the power wiring is in good condition and ensure that the power supply voltage is within the working range of the solenoid reversing valve. If the power supply voltage is unstable or out of range, adjust or install a voltage stabilizing device in time. Appearance inspection: Check the appearance of the solenoid reversing valve for damage, deformation or leakage. If there is any abnormality, it should be dealt with or replaced in time. 2. Regular cleaning and internal cleaning: According to the usage conditions, regularly disassemble the solenoid reversing valve for internal cleaning. Remove impurities and dirt on the valve core, valve seat and other parts to ensure that the channels in the valve are unobstructed. External cleaning: Keep the outside of the solenoid reversing valve clean to prevent dust, oil and other impurities from entering the valve. Wipe the surface of the valve body with a clean cloth to keep it dry and clean. 3. Selection of lubricating oil for lubrication and maintenance
