What is the essential difference between an electric ball valve and a pneumatic ball valve?

As follows: pneumatic ball valve is a ball valve with a pneumatic actuator, the execution speed of the pneumatic actuator is relatively fast, and the fast switching speed is seconds, so it is usually called pneumatic quick shut-off ball valve. Pneumatic ball valves are usually equipped with a variety of accessories, such as solenoid valves, air source treatment triplets, limit switches, controllers, control boxes, etc., to achieve local control and remote centralized control, and the valve can be controlled in the control room, without running to the scene to manually control, which saves human resources and time and safety to a large extent.

The aspects that need to be paid attention to in the selection of pneumatic ball valves are:

1. The working principle of pneumatic ball valve is to rotate the valve core to make the valve unblocked or occluded. The ball valve switch is lightweight, small in size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, the sealing surface and the spherical surface are often in a closed state, not easy to be eroded by the medium, and have been widely used in various industries.

2. Pneumatic ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium.

3. Pneumatic ball valve is a relatively new type of ball valve, which has some advantages unique to its own structure, such as frictionless switch, sealing is not easy to wear, and the opening and closing torque is small. This reduces the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict cutting of the medium.

Pneumatic ball valve model representation method:

Additional code for ball valves: V means the valve core has a V-shaped structure, D means low temperature, B means heat preservation, P means eccentric structure, U and S and DY mostly represent top-mounted type;

Ball valve name code: Q means ball valve;

Ball valve drive code: 6 means pneumatic;

Connection code: 1 means internal thread, 4 means flange type, 6 means welding, 7 means clamp type.

Hello landlord, the pneumatic ball valve is an automatic device that uses the air source as the power to drive the opening or closing of the ball valve, so as to realize the opening and closing of the pipeline medium or the purpose of adjustment. The electric ball valve uses electric energy as the power to connect the electric actuator to drive the ball valve to achieve the purpose of switching or adjusting the pipeline medium.

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.

One. Electric valves use electric motors for power, and pneumatic valves use compressed air for power.

1) Advantages of electric valves: good effect on liquid medium and large pipe diameter gas, not affected by climate. It is not affected by the pressure of air compressor. Disadvantages: high cost, not good in humid environment.

2) Advantages of pneumatic valves: good effect on gaseous medium and small diameter liquid, low cost, easy maintenance. Disadvantages: Affected by the fluctuation of air compressor pressure, it is easy to be affected by the water content of air compressor in the northern winter, resulting in the freezing and non-operation of the transmission part.

Two. Generally, pneumatics are faster than electric, and electric ones are dual-purpose flashlights. The pneumatic and pneumatic dual-use ** is relatively high.

Three. Electric valves are used in some places with large pipe diameters, because pneumatics are difficult to do, but the stability of electric valves is not as good as pneumatic, the switching speed is slow, and the actuator will have teeth jamming for a long time. Pneumatic valves open and close quickly and accurately, but require a stable air supply.
