ATOS is a leading manufacturer of electro-hydraulic components, possessing advanced technology that enhances the performance of modern machinery through integrated hydraulic components with electronic devices.

ATOS products include: Hydraulic pumps, piston pumps, gear pumps, axial piston pumps, vane pumps, cylinders, relief valves, stack valves, solenoid valves, amplifiers, solenoid directional valves, pressure reducing valves, check valves, and control valves.

ATOS vane pumps are pumps where vanes in the rotor slots contact the pump housing (stator ring), pushing the drawn-in liquid from the inlet side to the outlet side.

ATOS vane pumps are pumps where vanes in the rotor slots contact the pump housing (stator ring), forcing the drawn-in liquid from the inlet side to the outlet side. ATOS proportional valves actually have many disadvantages: high energy consumption, prone to failure, poor contamination resistance, high price, etc. Their only advantage is their highest dynamic performance among all hydraulic valves. This single advantage makes servo valves necessary in many applications with high dynamic performance requirements, such as aircraft and rocket servo control and turbine speed regulation. For applications with lower dynamic requirements, proportional valves are generally preferred.

ATOS proportional valve structure and working principle:

When the input signal increases, the supply solenoid valve pilot valve 1 switches, while the exhaust solenoid valve pilot valve 7 is 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, and the air pressure acts 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, a rapid comparison and correction is performed with the target value until the output pressure is proportional to the input signal, thus achieving a proportional change in output pressure to the input signal. Because it lacks a nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.

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.
