1.Structure of  Ball Valve Description

Threaded ball valve is closed is a ball, ball around the center line of the body as a rotation to achieve a kind of open and close the valve.
Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Two type ball valve, three type ball valve, is widely used in recent years a new type of valve, the valve average installation. And ball valve is a kind of ball valves, threaded pipe connection is screwed connection, and flanged ball valves, welded ball valve, etc.

2. Main Features of the Ball Valve

• Small flow resistance;

•  Simple structure

• Small volume, light weigh

• Small volume, light weigh

•  Easy to operate, open and close quickly, facilitate remote contro

• Easy maintenance, sealing ring, which generally remove easy to change

• Full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through does not cause the valve sealing surface erosion.

4.FAQ

1. What's are the characteristics of ball valve?

The distinct feature of a ball valve is the sealing surfaces between the gate and seats are planar, so ball valves are often used when a straight-line flow of fluid and minimum restriction is desired. The ball valve faces can form a wedge shape or they can be parallel. 

2. What is the work principle of ball valve

 The ball valve faces can form a wedge shape or they can be parallel. Ball valves are primarily used to permit or prevent the flow of liquids, but typical ball valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, ball valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Ball valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:Where is the hydrant main valve?
There is a gate valve at the elbow below the hydrant
Q:What is the purpose of the valve?
6. Indicate and adjust the level of the liquid. Such as liquid level indicator, liquid level regulator, etc..7, other special uses. Such as temperature control valve, over-current protection, emergency shut-off valve and so on. In the above valves, the valve used to connect and cut off the medium flow in the pipeline, the use of the total number of about 80% of the total number of valves.
Q:Where is the valve used?
Oil and gas pipelines, gas stations, gas stations, petrochemical plants, water plants, etc..The valve (Valve) is a mechanical device that controls the flow, flow, pressure, temperature, etc. of a fluid medium. The valve is the basic component of the piping system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:What do you mean by "P54" in the valve z962y-p54 100V?
1, P54 is the valve body temperature is greater than or equal to 545 degrees, 100V is 10Mpa, that is, 100 kilograms, the valve name on all.2, valve (Famen) is a fluid conveying system control components, with cut-off, regulation, diversion, and prevent reverse flow, voltage regulation, shunt or overflow, pressure relief and other functions. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:The valve is rusty and can not be opened. What shall I do?
Remove the handle and lever the stem rotation with a wrench,
Q:What are the major brands of valves abroad?
Fisher (Emerson's brand, pneumatic head and regulating valve is good) mountain Wu (Japan's control valve is doing well)
Q:The valve of the solar energy was broken by me. Do you know what is called?
An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
Q:What is called protective valve, and other valves what is the difference?
Protection valve should be in the air defense valve, can be copper gate valve. (according to the specific use of civil air defense requirements, design institute does not count).2, while the protection valve should be a locking device with the valve, not the general valve can be replaced.
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Material is the same, the fuse will not cause shrinkage when you can use
Q:How many valve enterprises in China's valve industry?
Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same
