Multi Rotary Valve Electric Actuator Choose The Right One
Jul 07, 2017

First, the description of the Multi Rotary Valve Multi Rotary Valve Electric Actuator  to do the name

Multi Rotary Valve Multi Rotary Valve Electric Actuator s in the market called a lot, it is easy to confuse, in fact, this is based on industry classification. In the valve industry classification, the Multi Rotary Valve Multi Rotary Valve Electric Actuator  called the valve electric device, referred to as electric devices, and the valve industry practitioners will be referred to as the Denso. In the instrumentation industry classification, belonging to a kind of actuator, so called Multi Rotary Valve Multi Rotary Valve Electric Actuator  or Multi Rotary Valve Multi Rotary Valve Electric Actuator .

Second, the definition of Multi Rotary Valve Multi Rotary Valve Electric Actuator 

Baidu Encyclopedia is widely defined as: a can provide linear or rotary motion of the drive device, which uses a certain drive energy and work under the action of a certain control signal. The actuator uses liquid, gas, electricity, or other energy sources and converts it into a drive by means of a motor, cylinder, or other device.

In the valve industry, this statement is more specific: valve electric device is to achieve the valve program control, automatic control and remote control indispensable drive equipment, the movement process can be travel, torque or axial thrust to control the size. As the valve operating characteristics and utilization of the valve depends on the type of valve, the device work norms and valves in the pipeline or equipment on the location. 

Through the understanding of the above definition, we know that Multi Rotary Valve Multi Rotary Valve Electric Actuator s in real life is widely used, such as: electricity, metallurgy, petroleum, chemical, paper, sewage treatment and other industries. Through the power-driven valves and similar equipment, to complete the human can not and the task, such as: excessive torque requirements or the valve in a harsh environment.

Third, how to choose the appropriate Multi Rotary Valve Multi Rotary Valve Electric Actuator 

How can you choose a suitable electric device? From our electric device sales point of view can also be said that we need what parameters to determine what kind of Multi Rotary Valve Multi Rotary Valve Electric Actuator s customers need it? The following detailed explanation:

Of course the simplest is that the customer directly provides the type of Multi Rotary Valve Multi Rotary Valve Electric Actuator which is the easiest to determine, but there is a problem here, there are many models of Multi Rotary Valve Multi Rotary Valve Electric Actuator s on the market, and thus also cause some trouble for comparison between products. ,

Second, determine the power device to output the force or torque (torque)

For multi-turn electric devices, part of the rotary electric device, angular travel Multi Rotary Valve Multi Rotary Valve Electric Actuator  three, the most important parameter is the torque, the unit is N.m. The opening or closing of the valve requires the moment to act on the top, if the torque is small, it may lead to can not turn off, can not open.

The most important parameter for a straight-stroke Multi Rotary Valve Multi Rotary Valve Electric Actuator  is force, the unit is N. The same force if the small will cause the valve can not be opened or closed.

Therefore, in the electric device selection process, follow a simple principle: would rather choose large, can not choose small.

Third, the electric device functional selection

You need to determine what kind of function you want the electric device to achieve, generally divided into three categories:

The first type: ordinary type electric device Such a motor has a simple dial to display the valve switch, and the external control needs electric control box, be regarded as the most basic model.

Second class; electromechanical integrated electric device. Such electric device comes with control box, the so-called mechanical and electrical integration. With liquid crystal display, you can feedback 4 ~ 20mA standard signal, you can determine the valve fully open, fully closed, and the uncertainty of the middle position, that is, switch control.

The third type: Adjustable electric device, and mechanical and electrical integration of the difference between the different ways of control; analog control, can receive and feedback 4 ~ 20mA standard signal, which can achieve accurate adjustment of the valve, you can determine the valve Full open, fully closed and precise intermediate position.
