4WEH16 electro-hydraulic directional valve is a composite product of electromagnetic directional valve and hydraulically controlled directional valve. Its core advantages are reflected in high flow control capability, fast response and high reliability, compact structure and modular design, flexible control method, adaptability to complex working conditions, long life and low dimensionality. Protection of six major aspects, specifically as follows: 1. High flow control capability 4WEH16 electro-hydraulic directional valve is specially designed for hydraulic systems where the flow exceeds the normal working range of the electromagnetic directional valve. Its maximum flow can reach 1100L/min, which can effectively control the flow direction of large flow hydraulic oil. For example, in equipment such as steel rolling mills and injection molding machines that require large-flow hydraulic drive, this valve can ensure that actuators (such as hydraulic cylinders and hydraulic motors) receive stable and sufficient hydraulic power to avoid slow action or stuck problems caused by insufficient flow. 2. Quick response and high reliability electromagnetic pilot control: Quickly switch the pilot oil circuit through the solenoid valve to achieve millisecond-level response of the main valve core.

The installation method of the superimposed hydraulic control check valve is as follows: foundation preparation ensures that the installation environment is dry, dust-free and well-ventilated, provides stable foundation support, and reserves enough space for subsequent maintenance and repair. Prepare wrenches, screwdrivers, seals and other tools, check the appearance of the valve body for damage or rust, and clean the interior and connecting pipes of impurities. Component confirmation and cleaning: Confirm that the valve body specifications and models meet the design requirements, and check that the nameplate parameters match the system. Clean the pipe section at the installation location to ensure that the surface is smooth and free of rust to prevent impurities from affecting the sealing. Determine the direction and position. Select the installation position according to the design requirements of the hydraulic system, and ensure that the medium flow direction is consistent with the arrow mark on the valve body. The superimposed hydraulic control check valve must be placed on the bottom layer (close to the base plate) to prevent pressure maintenance failure. During stacking installation and bolt fixing, place the O-ring side of the stacking valve toward the base plate to ensure that the oil holes are aligned without misalignment. Use grade 12.9 high-strength extension bolts to penetrate all valve bodies and press diagonally

4WE10 solenoid directional valve is usually installed on the bottom plate, and the connection method is welding. During installation, the axis must be ensured to be horizontal, and the specific steps and safety regulations in the product manual must be followed. The following are the specific installation points: Installation method: 4WE10 solenoid directional valve is usually installed with a base plate. This installation method is convenient for fixing and connecting the pipeline system, ensuring the stability of the valve during operation. Connection method: During the installation process, the connection method of 4WE10 solenoid directional valve is usually welding. This requires the installer to have certain welding skills to ensure the sealing and strength of the connection and prevent hydraulic oil leakage. Installation precautions: Horizontal installation: The axis of the electromagnetic reversing valve should be kept horizontal when installed, and tilted or vertical installation is not allowed. This is to ensure that the valve core inside the valve can move freely without being affected by gravity, thereby ensuring the normal operation of the valve. Follow product manual: Before installation, product manual should be read carefully

The 4WE10 single-head electromagnetic directional valve is a key control component widely used in industrial hydraulic systems. Its core function is to control the flow direction, pressure and flow rate of hydraulic oil through electromagnetic force to achieve automated movement and operation of mechanical components. The following is an analysis from the three dimensions of functional principles, application scenarios, and technical advantages: 1. Functional principle: combination of electromagnetic drive and hydraulic control. The 4WE10 single-head electromagnetic directional valve adopts the design of electromagnetic coil-driven directional spool valve. Its working principle is based on the synergy of electromagnetic force and hydraulic pressure: Power-on state: When the electromagnetic coil is energized, a magnetic field is generated, which attracts the valve core to move and changes the hydraulic oil path. For example, in hydraulic cylinder control, movement of the spool allows hydraulic oil to enter one side of the cylinder, pushing the piston into motion. Power-off state: the electromagnetic force disappears, the spring or hydraulic pressure resets the valve core, and the flow direction of the hydraulic oil changes or is cut off. This design enables precise start, stop and direction switching of the hydraulic system. Structural features:

The installation of the stacked relief valve must follow a standardized process, combined with the design requirements of the hydraulic system, and ensure its stable performance through standardized operations. The following are the specific installation methods and key steps: 1. Prepare the environment and tools before installation to ensure that the installation environment is dry, dust-free, and well-ventilated to prevent impurities from entering the hydraulic system. Prepare tools such as wrenches, screwdrivers, seals, pipes, etc. and check their integrity. Component inspection: Check whether the certificate of qualification, operating instructions and spare parts of the stacked relief valve are complete. Confirm that the valve body has no packaging damage or foreign matter, the oil port has not been opened, and all components are tightly connected without leakage. Clean the valve body and connecting parts with kerosene to remove oil dirt and impurities. System matching confirms that the model, diameter and parameters (such as pressure regulating range) of the superimposed relief valve are consistent with the hydraulic system design requirements. Check the cleanliness of the hydraulic oil. Contamination particles must meet ISO 4406 grade requirements (usually ≤18/16/13). 2. Basics of installation sequence and steps

Precautions for the use of the 4WE10 solenoid directional valve are as follows: 1. Installation and connection Installation direction The axis of the solenoid directional valve must be installed in the horizontal direction. Vertical installation may cause the valve core, armature and other parts to reverse or reset abnormally due to the influence of gravity. The connection method should be coordinated with the installation and connection methods of other hydraulic valves in the hydraulic system, and the appropriate installation and connection method should be selected. For electromagnetic reversing valves with plate-type connection, O-rings must be used to seal each oil port and the installation base plate. The surface of the base plate should be ground and processed to ensure flatness to avoid oil leakage. When installing the fixing screws, the fixed connection screws should be evenly stressed to prevent the valve body from deforming or the valve core from being stuck. 2. The matching voltage of the electrical control power supply must be consistent with the coil voltage to avoid coil burnout. Electromagnets are divided into DC and AC, and the appropriate model needs to be selected according to the control power supply parameters. Interlocking design The two electromagnets of the double-solenoid solenoid valve cannot be energized at the same time. When designing the electronic control system of hydraulic equipment, the action of the two electromagnets should be
