Spot ATOS Atos AGRCZO-AEB-NP-20/210/I/P

Spot ATOS Atos AGRCZO-AEB-NP-20/210/I/PThe ATOS Atos proportional directional valve in Italy can only be operated remotely to function properly, but if the interval between two remote operations exceeds one day, there will be no response. Based on the fault symptoms, it is believed that it may be caused by electrical control failure. Firstly, check the electrical control signal and proportional valve coil to confirm that there is no problem with the electrical part and eliminate electrical factors. The on-site use, maintenance, and repair of proportional directional valves have summarized a set of practical and feasible usage and maintenance experience, providing reference for the use, maintenance, and repair of such high-performance directional valves. This can effectively extend the service life of such valves, reduce the occurrence of failures, and lower the consumption of spare parts. By replacing the ordinary electromagnet in the electromagnetic directional valve with a proportional electromagnet, the Atos ATOS proportional directional valve forms a direct acting proportional directional valve. Proportional solenoid can not only rotate the valve core, but also continuously or proportionally change the displacement stroke, thereby continuously or proportionally changing the flow area between the connecting oil ports. Therefore, the proportional directional valve can not only change the direction of the liquid flow, but also control its speed, which is suitable for controlling the speed and position of the general bending machine mechanical actuator. It is a widely used proportional control component. In the case of high flow, a pilot operated proportional directional valve should be used. Atos ATOS proportional directional valve can not only control direction, but also control flow. ATOS electromagnetic directional valve, also known as solenoid valve, is a conversion component between hydraulic control system and electrical control system. It uses the suction force of the energized electromagnet to push the slide valve core to move, changing the oil flow interruption to achieve the reversing, starting, and stopping of the actuator. According to the structural form of the electromagnet, it can be divided into AC type, DC type, and self regulating type; According to the specifications of the working power supply, it is divided into AC 11OV, 220V, and 380V; DC 12V, 24V, 36V, etc; According to whether the armature of the electromagnet is immersed in oil, it can be divided into wet and dry types; According to the working position and the number of oil ports, there are two position two to three position five connections, etc.

ATOS electromagnetic directional valve is an industrial equipment controlled by electromagnetic technology, which is an automation basic component used to control fluids. It belongs to actuators and is not limited to hydraulic and pneumatic systems. It is used in industrial control system to adjust the direction, flow, speed and other parameters of medium. Electromagnetic valves can be used in conjunction with different circuits to achieve the desired control, while ensuring the accuracy and flexibility of the control. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. Commonly used ones are one-way valves, safety valves, directional control valves, speed regulating valves, etc.

Installation precautions for ATOS electromagnetic directional valve:

① The axis of the hydraulic cylinder solenoid directional valve must be installed in a horizontal direction. If installed in a vertical direction, it will be affected by the weight of parts such as the valve core and armature, which will cause abnormal directional or resetting.

② Plate connected electromagnetic directional valve, the installation base plate surface should be ground and processed, and there should be flatness requirements, without protrusion. The installation screws should not be loosened too much, otherwise oil will leak from the joint between the plate type electromagnetic directional valve and the base plate.

③ When repairing the directional valve of the hydraulic cylinder, attention should be paid to the assembly direction of the valve core. Generally, the shoulders on both sides of the reversing valve body are symmetrical, while the distance between the shoulders on both sides of the valve core is mostly asymmetrical. Therefore, during assembly, directionality should be maintained, and they should be arranged in order during maintenance. If installed incorrectly, it will cause malfunction.

④ When installing various valves, attention should be paid to the orientation of the inlet and return ports. Some valves may cause accidents if the inlet and return ports are installed in reverse.

⑤ To avoid air infiltration into the valve, the connection should ensure good sealing.

⑥ For the convenience of installation, some valve components often have two holes with the same function, and the unused one needs to be blocked after installation.

⑦ Valves installed with flanges for hydraulic cylinders should not have screws tightened too tightly, as sometimes tightening can cause poor sealing. When tightening is necessary, if the original seal or material cannot meet the sealing requirements, the form or material of the seal should be replaced.

⑧ Generally adjusted valves increase flow and pressure when rotated clockwise, and decrease flow or pressure when rotated counterclockwise.

Spot ATOS Atos AGRCZO-AEB-NP-20/210/I/PThe Italian ATOS Atos proportional directional valve uses electro-hydraulic control to achieve directional control. Its principle is: analog signal input amplification card, processed signal controls a small diameter proportional valve, the small diameter proportional valve and the large diameter hydraulic control valve are combined together, the small diameter proportional valve controls the large diameter hydraulic control valve, and the large diameter high flow hydraulic control valve controls the fast and slow extension and retraction of the oil cylinder. By using electronic control to achieve throttling control of flow, the Atos ATOS proportional directional valve, since it is throttling control, inevitably has energy loss. Unlike other valves, servo valves have greater energy loss because they require a certain flow rate to maintain the operation of the pre stage control oil circuit.

The Italian ATOS Atos proportional directional valve is used as a pilot stage to control the forward and reverse opening of the hydraulic directional valve based on the outlet pressure, thereby controlling the direction and flow rate of the liquid flow. The pilot stage electro-hydraulic proportional pressure reducing valve consists of two proportional electromagnets 2 and 4 and a valve core 3. When electromagnet 2 receives an electrical signal, the pressure reducing valve spool 3 moves to the right. The oil supply pressure sound is reduced through the right valve port and then fed back to the right end of spool 3 through the L port and b, balancing with the electromagnetic force of electromagnet 2. The ATOS proportional directional valve reduces the pressure, which is independent of the fuel supply pressure and proportional to the input signal current. The depressurized oil from the bending machine acts on the right end of the reversing valve spool through the channels Ni and C, causing spool 5 to move to the left, opening the valve port from P to B, and compressing the left end spring. The movement of valve core 5 is proportional to the magnitude of the control oil pressure, and the opening size of the valve port of the Atos ATOS proportional directional valve is proportional to the input current. Similarly, when the proportional electromagnet 4 is energized, the pressure oil is output from P through A. Junling Industrial Equipment (Shanghai) Co., Ltd
