German Doldr imported electric flange butterfly valve is a precision control valve with unique features and advantages. Its structure is composed of valve body, butterfly plate, valve seat, valve stem, worm gear, worm and other components, and the design is reasonable and compact, which can achieve precise opening control and flow regulation. One of the biggest features of this valve is its flange connection, which makes it suitable for all kinds of pipes and equipment, with a wide range of applicability. At the same time, its electric actuators are manufactured using advanced technology and can be driven using alternating or direct current, making them easy to operate and maintain.
The seal between the butterfly plate and the valve seat adopts soft seal or metal seal, which has reliable sealing performance and can effectively prevent medium leakage. Flanged electric butterfly valves also have the advantage of automatic control. It can be connected with various control systems to achieve intelligent control. For example, it can be combined with PLC control system to achieve remote control and automatic adjustment, and improve the degree of automation and production efficiency. In the event of a failure of the automatic control system, the valve can also be operated manually to ensure the continuity and stability of the production process.
In addition, the manufacture and maintenance of flanged electric butterfly valves are also relatively convenient. Its structure is simple, the number of parts is small, and it is relatively easy to repair and replace. At the same time, the valve also has the advantages of small size, light weight and convenient operation, making it widely used in various industrial fields.

The imported electric flange butterfly valve is a well-designed valve with a variety of advantages and applications.
Advantages: light size, can be opened and closed quickly, and the torque required for operation is small, convenient and labor-saving.
Flexible installation, can be installed at different locations of the pipeline, and easy maintenance.
The sealing material is resistant to aging and corrosion, and can be replaced, and the sealing performance is good.
Electric actuators are available in a variety of functions, including intelligent, switched, and signal-output functions.
The electric actuator has good stability, constant thrust and is able to resist deviation.
It is treated with overall painting or baking paint to prevent rust and improve the durability of the valve.
It has a large flow capacity, a small flow resistance coefficient, a relatively simple structure and easy maintenance.
Application: Widely used in petroleum, chemical, metallurgy, electric power and other industrial fields, can be used to regulate and cut off the flow of various media, suitable for high temperature, high pressure, corrosive media and other special working conditions.
It also plays an important role in the field of water treatment, which can control the flow of water, and is widely used in urban water supply, drainage, sewage treatment and other fields.
In the field of air conditioning and HVAC, imported electric flange butterfly valves are widely used in air conditioning and HVAC systems to control the flow of cooling water, heating water and other media, to achieve temperature regulation and energy consumption control, and to improve the comfort of the indoor environment.
