Presses are classified according to the basic principle of the valve

Presses are classified according to the basic principle of the valve

(1) Press switch control valve

An element that controls the continuous relationship of the various flow passages in the hydraulic system of the press by manipulating the connection and interruption of the flow of working fluid. It is called an on-off control valve. Each flow channel controlled by this kind of valve has only two working positions: open or closed, and the usual directional controls are both on-off valves.

(2) Press fixed value control valve

The basic control principle of this element is through its internal given device (usually a spring). make a parameter in the hydraulic system<-A amount is the pressure} to keep a constant value. Common pressure control valves are fixed value control valves.

(3) Press proportional control valve

This is an element that continuously controls the controlled parameters (pressure and flow) with a given input signal variation law. The controlled parameter changes in proportion to the input signal. All kinds of electro-hydraulic proportional valves belong to proportional control valves.

(4) Press control valve

The basic working principle of the servo control width is as follows. According to the difference between the input multiplier and the feedback signal (deviation signal). Automatically control and adjust the flow and pressure of the working liquid and other parameters. Such as electro-hydraulic flow valve, electro-hydraulic pressure valve, etc.

(5) Press digital control valve

This is an electro-hydraulic valve controlled by digital multiples, which can be directly connected with a computer to achieve precise control of parameters such as pressure and flow. At present, the more mature applications are precision and pulse width modulation digital control valves.

There are a lot of businesses today that are very much in demand and one of them is a mechanical power press.

To know more about and the market trends, go to World Press Machine.

mechanical power press has a very good repute over the global market.

While the productivity and efficiency benefits of automation are unequivocal for manufacturing mechanical power press, the need for skilled humans to operate, utilize and advance technologies is equally unmistakable.
