ATOS Proportional Valve AGMZO-A-10/315 Shanghai In Stock

ATOS proportional valves can control flow in two ways: One is on/off control: either fully open or fully closed, the flow is either at its maximum or minimum, with no intermediate state, such as ordinary solenoid direct-flow valves, solenoid directional valves, and electro-hydraulic directional valves. The other is continuous control: the valve port can be opened to any degree as needed, thereby controlling the flow rate. These valves can be manually controlled, such as throttle valves, or electrically controlled, such as proportional valves and servo valves. Therefore, the purpose of using proportional valves or servo valves is to achieve throttling control of flow rate through electrical control (of course, pressure control can also be achieved through structural modifications). Since it is throttling control, there is inevitably energy loss. Servo valves differ from other valves in that their energy loss is greater because they require a certain flow rate to maintain the operation of the pre-stage control circuit.

ATOS Proportional Valve Extended Information---Automatic control of electrical proportional valves can be divided into intermittent control and continuous control. Intermittent control is on/off control. Pneumatic control systems use low-frequency on-off directional valves to control the airflow. Pressure reducing valves regulate the required pressure, and throttle valves regulate the required flow rate. To achieve multiple output forces and speeds, this traditional pneumatic control system requires multiple pressure reducing valves, throttle valves, and directional valves. This not only increases the number of components, raising costs and complicating the system, but also requires manual adjustment of many components beforehand. Electro-proportional valve control is a continuous control method, characterized by output varying with input, exhibiting a proportional relationship between the two. Proportional control can be open-loop or closed-loop.

ATOS Proportional Valve Structure and Principle:

When the input signal to the ATOS proportional valve increases, the supply solenoid pilot valve 1 switches, while the exhaust solenoid pilot valve 7 remains in the reset state. The supply pressure then enters the pilot chamber 5 from the SUP port through valve 1. The pilot chamber pressure rises, acting on the diaphragm 2, opening the supply valve core 4 connected to diaphragm 2 and closing the exhaust valve core 3, generating output pressure. This output pressure is fed back to the control loop 8 via pressure sensor 6. Here, it is quickly compared and corrected with the target value until the output pressure is proportional to the input signal, thus demonstrating that the output pressure changes proportionally to the change in the input signal. Because there is no nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.
