Single-head electromagnetic reversing valve is an automation component that controls the flow direction of fluids (such as gases, liquids) through electromagnetic force, and is widely used in industrial automation, hydraulic/pneumatic systems, mechanical equipment and other fields. Its core advantage lies in its compact structure, accurate control and quick response. The following is a detailed analysis of its advantages: 1. Compact structure, flexible installation, miniaturization design, single-head electromagnetic reversing valves usually adopt an integrated structure, integrating the solenoid coil, valve body and seal into a single module, small in size and light in weight, suitable for space-constrained occasions (such as machine tools and robot joints). For example, in a compact hydraulic system, a single head valve can replace multiple traditional valves, reducing pipeline connections and reducing leakage risk. The diverse installation methods support a variety of installation interfaces such as plate, tube, flange, etc., which can be installed vertically or horizontally to meet the needs of different equipment layouts. Some models are equipped with quick connectors, which can be installed or replaced without tools, shortening equipment debugging time. two,

4WEH16 electro-hydraulic reversing valve is a high-performance directional control valve that combines electromagnetic control and hydraulic drive. It is widely used in hydraulic systems that require high-precision, rapid response and large flow control. Its core features include electromagnet drive, hydraulic pilot control, median functional diversity and high pressure/flow adaptability. The following is its specific application scope and analysis: 1. Core features and advantages Electromagnetic-hydraulic composite control generates electromagnetic force through the electromagnetic force, which drives the pilot valve core to move, and then the pilot hydraulic oil pushes the main valve core to redirect, realizing the function of low pressure control and low flow control and large flow. Advantages: fast response speed (millisecond level), high control accuracy, low energy consumption (the electromagnetic power only requires a few dozen watts). The diversity of median functions provides a variety of median functions (such as O-type, H-type, Y-type, etc.), and the system pressure holding, unloading or differential connection mode can be flexibly selected to meet different working conditions. High pressure/flow adaptability rated pressures are usually

The usage method of superimposed relief valve mainly involves installation, pressure adjustment and daily maintenance. The following is a detailed introduction: Installing superimposed relief valves is usually installed between the reversing valve and the bottom plate. Superimposed valves of the same diameter are superimposed in a certain order and connected in series with bolts. When installing, you need to pay attention to the damping holes on the oil circuit or main valve core. The pressure valve unit with the damping hole is the pressure valve unit, and the direction valve unit without the damping hole is the direction valve unit. Ensure the connection is correct. For example, during the installation process, it is necessary to ensure that the connection between the main oil circuit of the cone valve and the pilot valve and the control oil circuit is accurate to avoid the system from operating normally due to connection errors. Pressure adjustment and adjustment steps: When performing pressure adjustment, first loosen the lock nut and rotate the pressure adjustment screw clockwise, and the pressure will rise. After adjustment is completed, the lock nut must be tightened to prevent the pressure adjustment screw from loosening, resulting in unstable pressure. Note: The minimum adjustment pressure is equal to the characteristics of the minimum adjustment pressure

The superimposed hydraulic control check valve is a hydraulic component that realizes the reverse flow of the check valve by controlling the fluid pressure. Its working principle and characteristics are as follows: 1. Core structure The superimposed hydraulic control check valve is mainly composed of the following components: steel valve body: as the main structure, providing the installation and connection foundation. One-way valve assembly: Contains one or two check valves (such as check valves 2 and 3) to ensure one-way flow of oil. Pilot piston: The piston moves by controlling the oil circuit pressure to enable the opening or closing of the check valve. Pilot cone valve core: Located in the main valve core of the one-way valve, ensuring the precise opening of the one-way valve and improving sealing. 2. Working principle forward flow (free circulation) When oil flows from the oil inlet (such as A1) to the oil outlet (such as A2), the check valve 2 automatically opens under the action of oil pressure and the oil passes freely. At this time, the pilot piston 4 is pushed to the right position, and the one-way valve 3 is also opened simultaneously through the action of the pilot cone valve core 5 to ensure the smooth flow of the oil circuit.

The advantages of 4WE10 solenoid reversing valve are as follows: high precision and reliability adopt a precision solenoid valve structure, with a control accuracy of up to 0.2%, meeting the needs of high-precision industrial. High-quality materials and precision processing technology ensure long-term and stable operation, long service life, and are suitable for harsh environments such as high pressure and high temperature. Compact structure and flexible installation, small size and light weight, save installation space and facilitate integration into complex hydraulic systems. It supports various installation methods such as plate type and tube type. The electrical connection can be connected individually or centeredly to meet different operating needs. Multifunctional control and efficient performance provide a variety of models such as two-way, two-way, two-way, three-way, three-way, and three-way, achieving accurate control of liquid on-off, direction, flow rate and flow rate. The maximum working pressure is 350 bar, and the maximum flow rate is 80 l/min (DC) or 60 l/min (AC), meeting the demand for large flow. The AC solenoid valve reversing time is short (0.03-0.05 seconds

The following key matters should be paid attention to when using the double-head solenoid solenoid valve (double solenoid solenoid valve) to ensure its normal operation and avoid failure: The axis of the solenoid reversing valve must be installed in a horizontal direction to avoid vertical installation, resulting in abnormal reversal or resetting of the valve core or armature due to gravity. The surface of the installation base plate needs to be ground and meet the flatness requirements to avoid oil leakage due to uneven installation surfaces. Ensure that there is enough space at both ends of the installation position for easy manual operation or replacement of the solenoid. The electrical connection and control power parameters (voltage, current type) must match the solenoid valve, otherwise it may cause the solenoid to fail to work properly or burn the solenoid. The dual solenoid cannot be energized at the same time. It is necessary to achieve action interlocking through the design of the electronic control system to avoid the valve core position being unfixed or the coil burning. Check the electrical connection status regularly to prevent failure caused by loosening or poor contact. The hydraulic system matches the reversing valve with the appropriate diameter according to the system flow rate, and
