Selling original Italian ATOS proportional valves

The Italian ATOS proportional valve is essentially an inexpensive and pollution resistant electro-hydraulic control valve. The development of proportional valves has gone through two paths. One is to replace the manual adjustment input mechanism of traditional hydraulic valves with proportional electromagnets. Based on traditional hydraulic valves, various proportional direction, pressure, and flow valves have been developed; The second is the development of some original electro-hydraulic servo valve manufacturers by reducing the design and manufacturing accuracy on the basis of electro-hydraulic servo valves.

Selling original Italian ATOS proportional valvesThe working principle is that the instruction signal is amplified by a proportional amplifier and outputs current proportionally to the proportional solenoid of the proportional valve. The proportional solenoid outputs force and moves the position of the valve core proportionally to control the flow rate and change the direction of the flow, thereby achieving position or speed control of the actuator. In some applications that require high precision in position or velocity, a closed-loop control system can also be formed by detecting the displacement or velocity of the actuator.

The Italian ATOS proportional valve consists of two parts: a DC proportional solenoid and a hydraulic valve. The core of the proportional valve for continuous control is the use of proportional solenoid. There are many types of proportional solenoid, but their working principles are basically the same. They are all developed according to the control needs of the proportional valve.

According to the Italian ATOS proportional valve control method, it refers to the classification based on the electrical mechanical conversion method in the pilot control valve of the proportional valve. Its electrical control part includes various forms such as proportional solenoid, torque motor, DC servo motor, etc.

(1) Electromagnetic electromagnetic valve refers to a proportional valve that uses a proportional electromagnet as an electrical mechanical conversion component. The proportional electromagnet converts the input current signal into force and displacement mechanical signals for output, thereby controlling parameters such as pressure, flow rate, and direction.

(2) Electric type refers to a proportional valve that uses a DC servo motor as an electrical mechanical conversion component. The DC servo motor converts the input electrical signal into rotational speed, and then outputs force and displacement through reduction devices and transformation mechanisms such as screw nuts, gear racks or gear camshafts, further controlling hydraulic parameters.

(3) Electro hydraulic refers to a proportional valve with a structure of a torque motor and nozzle baffle as the pilot control stage. Input different electrical signals to the torque motor and output displacement or angular displacement through the baffle connected to it (sometimes the armature of the torque motor is the baffle), change the distance between the baffle and the nozzle, and change the flow resistance of the oil sprayed from the nozzle, thereby controlling the transmission parameters.

Selling original Italian ATOS proportional valvesCompared with ordinary hydraulic components, it has the following characteristics:

(1) Electrical signals are easy to transmit and can be easily controlled over long distances.

(2) It can continuously and proportionally control the pressure and flow of the hydraulic system, achieve control over the position, speed, and force of the actuator, and reduce the impact during pressure changes.

(3) Reduced the number of components and simplified the oil circuit.
