The use of electric flange ball valves, what are the characteristics of pneumatic flange gate valves

The electric ball valve is a kind of rotary ball valve with an angle of 90 degrees, with excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, long service life, equal diameter of valve body channel and connecting pipe into a diameter, and the medium can flow through almost without loss. It is equipped with DKJ-, actuator with high-performance actuators such as Japanese tooling and West German Omron. In addition to controlling gas, liquid and steam media, the products are also suitable for controlling sewage and media containing fibrous impurities, and are widely used in petroleum, chemical industry, metallurgy, light industry, papermaking, power station, refrigeration and other fields.

Ball valve is an important type of valve, which is widely used in petrochemical industry, long-distance pipeline and other fields. The closing part of the ball valve is a ball (or part of a ball) with a hole, and the ball rotates with the valve stem to realize the opening or closing of the valve.

The ball valve can be fully closed and fully opened when rotated 90 degrees, compared with the gate valve and globe valve of the same specification, the ball valve is small in size and light in weight, which is convenient for pipeline installation.

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, Su Yan, 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.

Pneumatic flange gate valve is a valve controlled by pneumatic devices and has the following characteristics:

1.Quick Switching: Pneumatic flanged gate valves can be quickly opened or closed, making them ideal for applications where fluid flow needs to be cut off quickly.

2.High reliability: The pneumatic device of the pneumatic flange gate valve usually adopts the pneumatic piston or diaphragm structure, which has high reliability and stability.

3.High pressure: The structural design of the pneumatic flange gate valve enables it to withstand high pressures and is suitable for high-pressure fluid pipeline systems.

4.Corrosion-resistant: Pneumatic flanged gate valves are usually made of corrosion-resistant materials to adapt to the use environment of various corrosive media.

5.No leakage: The structural design of the pneumatic flange gate valve makes it have good sealing performance, which can effectively prevent fluid leakage.

6.Remote control: Due to the pneumatic control, the pneumatic flange gate valve can be connected with the automatic control system to achieve remote control and monitoring.

It should be noted that the installation and maintenance of pneumatic flanged gate valves is relatively complex and requires professional operation and management. In the selection and use, reasonable selection and configuration should be carried out according to the specific working conditions and requirements.

This is related to the material of the valve, and the following takes the Q41F-10S engineering plastic valve as an example.

First, the use of the product.

This series of ball valves is widely used in pipeline conveying lines with corrosive media, and is suitable for the working temperature of -40 140 according to different materials, and can realize emergency shut-off in accidents.

2. Features. 1.Engineering plastic series ball valves are made of corrosion-resistant thermoplastics such as FRPP, PVDF, CPVC, UPVC and other one-time injection molding.

It has strong corrosion resistance.

2.The sealing is reliable, and the opening and closing torque is small.

3.The fluid resistance is small, and the opening and closing are fast.

4.The structure is simple and the appearance is beautiful.

The electric ball valve (English name: electronic ball valve) is composed of electric actuator and ball valve together to form an electric ball valve. It is a kind of pipeline pressure element for industrial automation process control, which is usually used for remote opening and closing (on, off and off medium) control of pipeline media.

The electric ball valve standard GB T21465-2008 "Valve Terminology" is defined as: the opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the valve stem. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of fluids, among which the hard seal V-shaped ball valve has a strong shear force between the V-shaped ball core and the metal seat of the hardfacing cemented carbide, especially suitable for media containing fibers and tiny solid particles.

Electric ball valves are divided into electric flange ball valves, electric clamp ball valves, electric welded ball valves, and electric wire button ball valves. According to the sealing form, it is also divided into soft seal electric ball valve and hard seal electric ball valve.
