ATOS proportional valve DLHZO-TEB-SN-NP-040-L13/I in stock
$280.82
The Italian ATOS proportional valve uses electronic control to achieve flow throttling control (of course, pressure control can also be achieved through structural modifications). Since it is throttling control, there will inevitably be energy loss. The servo valve is different from other valves in that its energy loss is greater because it requires a certain flow to maintain the operation of the pre-stage control circuit.

When the input signal of the Italian ATOS proportional valve increases, the pilot valve 1 of the supply solenoid valve switches, while the exhaust solenoid 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, causing the supply valve core 4 connected to diaphragm 2 to open, and the exhaust valve core 3 to close, generating output pressure. This output pressure is fed back to the control circuit 8 through the 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 there is no nozzle-baffle mechanism, the valve is insensitive to impurities and has high reliability.
Features of the Italian ATOS proportional valve
1) It can achieve stepless adjustment of pressure and speed, avoiding the impact phenomenon during switching of normally open on/off valves. 2) Enables remote and program-based control.
3) Compared to intermittent control, the system is simplified, with a significant reduction in components.
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 hydraulic systems, and it is more sensitive to load changes.
Italian ATOS Proportional Valves
Italian ATOS proportional valves can control flow in two ways:
One is on-off control: either fully open or fully closed, the flow rate is either 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 include manually controlled ones, such as throttle valves, and electrically controlled ones, 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.
