When the load is zero, if the four-way spool valve is open, the pressure at port P equals the pressure at port T plus the pressure loss at the valve port (ignoring other pressure losses in the oil circuit). If the pressure loss at the valve port is very small, and the pressure at port T is zero, then the pressure at port P is insufficient to supply the pilot valve to actuate the main valve spool, causing the entire servo valve to fail. Therefore, the valve port of the servo valve is made relatively small, ensuring a certain pressure loss even when the valve port is fully open to maintain the normal operation of the pilot valve.

ATOS Proportional Directional Valve Features
ATOS proportional directional valves control flow in two ways: One is on/off control: either fully open or fully closed, with flow either at its maximum or minimum, without intermediate states, such as ordinary solenoid straight-through valves, solenoid directional valves, and electro-hydraulic directional valves. The other is continuous control: the valve port can open 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 or servo valves is to achieve throttling control of flow rate electronically (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 Directional Valve Overview:
ATOS Proportional Directional Valve Structure and Principle
When the input signal to the ATOS proportional directional valve increases, the pilot valve 1 of the supply solenoid valve 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, and the air pressure acts on the diaphragm 2, causing the supply valve core 4 connected to diaphragm 2 to open, while the exhaust valve core 3 closes, 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 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.
ATOS Proportional Directional Valve Features
1) Enables stepless adjustment of pressure and speed, avoiding the impact phenomenon during switching of normally open on/off valves.
2) Enables remote control and program control.
3) Compared to intermittent control, the system is simplified, and the number of components is greatly reduced. 4) Compared to hydraulic proportional valves, it is smaller, lighter, simpler in structure, and lower in cost, but its response speed is much slower than that of a hydraulic system, and it is more sensitive to load changes.
5) It uses less power, generates less heat, and produces less noise.
6) It will not cause a fire and will not pollute the environment. It is less affected by temperature changes.
