20mA control signal or 1-5vdc and 220VAC power supply. The electric ball valve has the advantages of small volume, light weight, good performance, simple matching and large circulation capacity. The electric ball valve can be used for working temperature: - 20 ℃ to + 200 ℃ (+ 350 ℃ to + 700 ℃) with working pressure of pn1.6-pn42.0mpa.

Regulating valve installation specification, electric control valve installation control valve used to adjust the flow of operating variables, from the control system as a whole, whether a control system is good or not, must be achieved through the control valve. The regulating valve becomes very important for the following reasons.

In recent years, the high-tech field represented by environmental protection and Internet has developed rapidly, which has also driven the development of other industries such as valves and pumps. These industries continue to change the mode of production, increase innovation, and gradually occupy a position in the market.

Stainless steel self-priming pump with vacuum auxiliary system is called stainless steel self-priming pump, which is characterized by shortening the suction time of self-priming pump and improving the operation efficiency of stainless steel self-priming pump in flood prevention and rescue. Vacuum pump for stainless steel

The acceptance experts believe that the undertaking units have extensively investigated the fish passing modes at home and abroad, as well as the upstream and downstream fish passing cases of pumps and turbines.

When it comes to the chemical pump, it is more and more widely used in industrial production, especially in the chemical field, the corrosion-resistant chemical pump is playing an increasingly important role.

The sludge filter press usually needs to be used together with the sludge feed pump. What influence does the pressure of the sludge feed pump have on the dewatering effect of the sludge filter press? Let's have a look.

In order to improve the efficiency of the pump itself, we should make great efforts in the design and manufacture of the pump, adopt advanced design and processing means to manufacture the pump, or adopt advanced technology to realize the utilization efficiency of the pump.

The development status of stainless steel chemical pump in China: stainless steel chemical pump is an energy-saving equipment, and in recent years, due to the continuous improvement of the quality of life, it has also begun to show a great momentum. The stainless steel chemical pump in China is growing year by year, which is applied to all aspects related to our life, such as water industry, urban construction, water equipment, environmental protection, etc etc.

It has been only a few decades since the rise of the Internet. It has spread all over the world and deeply rooted in the society. Network marketing has taken the opportunity to penetrate into all walks of life. As a potential stock in urban construction, the pump industry can not avoid it. The rise of the Internet will inevitably have a certain impact on the growing pump industry and may change the development of the pump industry in the future Show the track. Magnetic pump is a kind of pump widely used in the industrial industry, and the marketing of magnetic pump is naturally listed as a member of online marketing.

The horizontal centrifugal pump has the upper hand in both the use scope and the quality or process, which can be seen from the current market sales ratio. The horizontal centrifugal pump ranks first in the total number of sales in the market, and it seems that every year has better performance. Therefore, at present, the development and innovation of horizontal centrifugal pump will go through a relatively long period.
