Electric Butterfly Valve Features

Electric butterfly valve is one of the most widely used valves. Its popularity is due to the small friction between the sealing surfaces in the process of opening and closing. It is relatively durable; it has a small opening height; it is easy to manufacture, and it is easy to maintain. It can be applied at low pressure, but also for high pressure. Flanged center line butterfly valve is one of the popular products.

Electric butterfly valve: The opening and closing parts are disc type left and right open.

The features are:

1, simple structure, small size, easy installation;

2, small flow resistance coefficient, rapid opening and closing;

3, can be used for large diameter valves;

4, can use different sealing surfaces, use a variety of environments, including powdered, granular media.

Do You Know Features Of Electric Ball Valve？

  The electric ball valve is composed of an electric actuator and a cast iron ball valve. It is applicable to the process occasions and fluid control systems that have large pipeline pressure difference, strict sealing requirements, and cut off the pipeline medium.

Electric ball valve: The plug valve evolved and the opening and closing element was a sphere.

The feature is:

1. Low flow resistance;

2. Completely sealed under greater pressure and higher temperature;

3.It can quickly open and close;

4. Its sealing structure is better;

5. Valve body symmetry, and it can effectively withstand the pressure of the pipeline, handle high pressure conditions.

The Features Of Pneumatic Drive Type Butterfly Valve

The pneumatic drive type butterfly valve is a very important type in the cast iron butterfly valve. And it has a simple structure, small size, and light weight, and it is composed of only a few parts. And what you should do is only to rotate 90 degree to open and close quickly, because it is easy to operate, at the same time the valve has good fluid control characteristics.

When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.

Pneumatic drive type butterfly valve has two types of seals: elastic seal and metal seal. Elastic sealing valve, sealing ring can be mounted on the valve body or attached around the butterfly plate. 

The Working Principle Of The Butterfly Valve

 The butterfly valve is used to open and close the circular butterfly plate that rotates with the pungent to achieve the action of the electric valve, which is mainly used as a cut-off valve. It can also be designed to have the function of adjustment or paragraph valve and adjust the disc. Cast iron butterfly valve is more and more used in the low pressure caliber pipes.

The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. And it only need to rotate 900 to open and close quickly with simple operation, at the same time, the electric valve has good fluid control characteristics.

When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.
