What are the characteristics of the D81X handle signal groove butterfly valve?

1.The overflow area is large, the flow resistance coefficient is small, and the flow capacity is large;

2.The disc plate is made of integral rubberization, anti-aging, anti-radiation, and durable.

3.The grooved disc valve has compact structure, small size, light weight, flexible operation and convenient maintenance;

4.Reliable sealing performance, not limited by media injection (bidirectional sealing);

5.With carbon steel as the main material, the valve body is welded with thick-walled seamless pipe, and the valve plate is ductile iron, which is reliable in quality and beautiful in appearance.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Chaoda, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

1.Patented technology is used to make the valve seal more reliable and has a bi-directional sealing function.

2.The butterfly plate is streamlined, and the hydraulic abrasion resistance is small.

3.It is easy to install and can be quickly connected to other grooved fittings or valves at any angle.

4.The valve body is made of ductile iron, which is small in size and light in weight.

5.The opening and closing is light, the operation torque is small, and the opening and closing are light.

6.The non-crushing valve is coated with ductile iron and powder epoxy resin inside and outside, which can effectively prevent the corrosion of various acid and alkali media and can ensure durability.

7.The micro switch is installed in the worm gear box, which improves the ability of fire prevention, moisture and moisture, and improves the life and reliability of the communication device.

The signal is that when the handle is opened, the control opening indicator light is on (the valve has an opening switch), and the light is off when it is turned off. There is no non-signal butterfly valve with this feature.

The sealing mode of the handle groove butterfly valve, the connection between the rotating shaft and the butterfly plate is unique, and it is awarded a utility model patent by the state, and is widely used in the transmission medium pipeline, and is used in heating, pipeline, gas, petroleum, chemical, water treatment, fire protection, air conditioning, municipal, shipbuilding and other engineering systems to do the role of adjustment, and is also suitable for a variety of corrosive liquids, gases, solid powders and other media.

The main difference between the two is that the signal butterfly valve must be equipped with a fully open and fully closed valve position passive contact, which is used in the central control room to monitor the opening status and position of the valve, and is generally used in fire fighting places; The simple identification of the two, to put it bluntly, the signal butterfly valve is like a handle butterfly valve, that is, a travel switch is installed on the handle butterfly valve, so that the valve touches the travel switch when it is fully open or fully closed, and outputs an electrical signal. Of course, the acceptance requirements of the signal butterfly valve are higher than that of the ordinary butterfly valve, including the pressure test and the anti-electric shock of the travel switch, etc., and the national and industry standards have standards for these two valves.

Hopefully, the above description will give you a better understanding of these two valves.

A: The different transmission modes (handle or turbine) are mainly determined by the size of the valve and the opening and closing torque.

You have to say that Tianjin Waters is good, but it's not very cheap!

If you buy handle groove signal butterfly valve, you can consult the valve manufacturing enterprises here in Botou City, Hebei Province, because this area is the national valve production base, and many brand valve manufacturers are here.

1. Small and lightweight, easy to disassemble and maintain, and can be installed in any position.

2. The structure is simple and compact, and the 90° rotation opens and closes quickly.

3. The operating torque is small, labor-saving and lightweight.

4. Achieve complete sealing, and the gas test leakage is zero.

5. Choose different parts and materials, which can be applied to a variety of media.

6. The flow characteristics tend to be straight, and the adjustment performance is good.

7. The number of opening and closing tests is as many as 10,000 times, and the service life is long.

8. All pipelines that use gate valves, check valves, globe valves, plug valves, hose valves and diaphragm valves, especially in the fire protection system of high-rise buildings and pipeline systems that need to display the valve switch status, can be replaced by the valve.
