ATOS proportional valves differ primarily in the following aspects:

1. Different drive devices. Proportional valves use proportional electromagnets; servo valves use force motors or torque motors.

2. Different performance parameters. Hysteresis, dead zone, bandwidth, and filtration accuracy differ, leading to different applications. Servo valves and servo proportional valves are mainly used in closed-loop control systems, while other types of proportional valves are mainly used in open-loop control systems and closed-loop speed control systems.

2.1 Servo valves have no dead zone at mid-position, while proportional valves do.

2.2 Servo valves have a higher frequency response, reaching up to approximately 200Hz, while proportional valves generally have a maximum frequency of tens of Hz.

2.3 Servo valves have higher requirements for hydraulic fluid, requiring fine filtration to prevent clogging, while proportional valves have lower requirements.

3. Different valve core structures and machining precision. Proportional valves use a valve core + valve body structure, with the valve body also serving as the valve sleeve. Servo valves and servo proportional valves use a valve core + valve sleeve structure. 4. Different Neutral Position Functions. Proportional directional valves have neutral position functions similar to ordinary directional valves, while servo valves only have an O-type neutral position function (E-type for Rexroth products).

5. Different Rated Pressure Drops.

ATOS proportional valves have performance between servo valves and proportional valves.

ATOS proportional valves are a type of proportional valve used to control flow rate and direction.

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 on/off directional valves with low operating frequencies to control the opening and closing of the air path. Pressure reducing valves regulate the required pressure, and throttle valves regulate the required flow rate. This traditional pneumatic control system requires multiple pressure reducing valves, throttle valves, and directional valves to achieve multiple output forces and multiple movement speeds. This not only increases the number of components, raising costs and complicating the system structure, but also requires many components to be manually adjusted in advance. Electro-proportional valve control is a type of continuous control, characterized by an output that changes proportionally to the input, with a certain proportional relationship between the two. Proportional control can be divided into open-loop control and closed-loop control.

ATOS proportional valves can control flow in two ways: one is on/off control: either fully open or fully closed, with the flow rate either at its maximum or minimum, without intermediate states, 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 flow throttling control electronically (of course, pressure control can also be achieved through structural modifications). Since it is throttling control, there will inevitably be 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.
