Solution of proportional servo valve

Digital axis motion controllers are intelligent motion control solutions for modern equipment and systems: they are easy to set up and can realize optimal closed-loop control of displacement, speed or force of any electro-hydraulic axis through PC program.

The reliability of digital servo proportional valve is high, which can be comparable with the servo valve. It is the embodiment of proportional technology

Precision cover of valve core and valve sleeve, closed loop feedback, safety reset, high response, factory preset digital electronic amplifier, flow / pressure / position digital control.

The series of proportional valve products are complete, adhering to the modular design concept, flexible combination, matching with the corresponding electronic amplifier and shaft controller to realize the control of flow, pressure and direction.

Solenoid valve will be connected to the computer, the price is low. The structure of solenoid valve is simple and its price is low. Compared with other kinds of actuators such as control valve, it is easy to install and maintain. What's more, the automatic control system is much simpler and the price is much lower. Because the solenoid valve is controlled by switch signal, it is very convenient to connect with industrial computer. In today's computer popularization, the price drops sharply, the advantage of solenoid valve is more obvious. Solenoid valve action express, small power, light shape. The response time of solenoid valve can be as short as several milliseconds, and even the pilot operated solenoid valve can be controlled in tens of milliseconds. Because of its own loop, it is more sensitive than other automatic control valves. Properly designed solenoid valve coil power consumption is very low, belongs to energy-saving products; can also achieve only trigger action, automatically maintain the valve position, usually no power consumption. The size of solenoid valve is small, which not only saves space, but also is light and beautiful. The adjustment accuracy of solenoid valve is limited, and the applicable medium is limited. The solenoid valve usually only has two states of switch, and the valve core can only be in two limit positions, so it can not be continuously adjusted (there are many new ideas trying to break through, but they are still in the trial stage). Therefore, the adjustment accuracy is still limited. The electromagnetic valve has high requirements on the cleanliness of the medium, and the medium containing particles cannot be used. If it is impurities, it must be filtered first. In addition, viscous media can not be applied, and the viscosity range of specific products is relatively narrow. The solenoid valve has various types and wide applications. Although the solenoid valve has inherent deficiencies, the advantages are still very prominent, so it is designed into a variety of products to meet various needs, and has a wide range of uses.

The main features of the solenoid valve are that the external leakage is blocked, the internal leakage is easy to control, and the use is safe. Internal and external leakage is an element endangering safety. Other automatic control valves usually extend the valve stem, and the electric, pneumatic and hydraulic actuators control the rotation or movement of the valve core. It is necessary to solve the leakage problem of the long-term dynamic seal of the valve stem; only the electromagnetic force acts on the iron core sealed in the magnetic isolation sleeve of the electric control valve, and there is no dynamic seal, so the leakage is easy to be blocked. The torque control of the electric valve is not easy, and it is easy to produce internal leakage and even break the valve stem head; the structure of the solenoid valve is easy to control the internal leakage until it drops to zero. Therefore, the use of solenoid valve is particularly safe, especially suitable for corrosive, toxic or high and low temperature media.

The hydraulic cylinder produced by solenoid valve company meets the international standards of iso6020 and 6022, and the peak pressure is up to 350 PA. The hydraulic cylinder can be equipped with buffer device and sensor to detect piston position. In addition, it also produces servo proportional valve with valve core and valve sleeve. The adjustable flow pump of proportional servo valve can be up to 98 cm3 / R and can be equipped with flow electronic controller. The same type of radial piston pump can bear pressure up to 500 PA. Vane pump can be divided into fixed displacement or adjustable displacement, and can be used with PTO. Pump series products have a variety of options, different types of oil pumps can be connected together.
