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.

5.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: What is the use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism
- Watts is the origin of industrial water valve, after so many years of development, the current air-conditioning, water supply and drainage, fire, general valve Liwoci is most commonly used, compared with the best foreign brands.
- Q: Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!
- A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!
- Q: What valves are needed on the construction site?
- Order valves1, according to the use of place, use, and understand the relevant laws and regulations, specifications, standards, policies, approval may be used after the selection of valves suitable for various requirements;2, confirm the working conditions of valve, applicable medium, working pressure and medium temperature;3, determine the nominal diameter corresponding to the pipe: DN (mm), NPT, NPS (");4, determine the way to connect with the pipe: flange type, internal (external) thread type, welding type, clamp type, clamp type, card sleeve type, etc.;5, determine the valve operation mode of driving: manual, worm gear drive, pneumatic, electric, hydraulic, electromagnetic, electro hydraulic, etc.;6, confirm the types of valves: gate valve, globe valve, throttle valve, plunger valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, drain valve, pressure reducing valve and other special valves;7, determine the use of valves: switching type, adjustment type, safety type and so on;8, determine the valve shell and internal parts of the material: carbon steel, alloy steel, stainless steel, ductile iron, gray cast iron, copper alloy, aluminum alloy, plastic and so on;9, determine the valve sealing performance requirements, sealing level or sealing leakage;10, determine the valve coating requirements, packaging requirements, transportation requirements;11, special needs of the valve should also be determined: structure length, valve height, appearance size, flow resistance, emission capacity, flow characteristics, protection level, explosion-proof performance and other parameters;12, determine the valve installation position and posture.
- Q: What is the difference between the valve before the pump and the valve after the pump?
- Pump front valve: current limit; pump rear valve: limit pressure.Pump operating procedures: the pump must be closed before and after the valve, open the pump, slowly open the pump front valve, pump pressure normal, slowly open the pump, valve until all open. If the pump is in front and rear valves are opened, the pump is very easy to burn the motor.
- Q: What do you mean by "P54" in the valve z962y-p54 100V?
- P54 is the body temperature, heavy rain or equal to 545 degrees, 100V is 10Mpa, that is 100 kilogramsThere are all the valves on the nameplate
- Q: Air compressor out of the gas with what kind of valve control okay, globe valve or other?
- Air compressor all copper safety valve (AQ-20) (AQ-25)Air compressor, air release valve and so on. The air compressor rated exhaust pressure is divided into low pressure (0.7~1.0MPa), medium pressure (1.0~10MPa), high pressure (10~100MPa) and ultra high pressure (100MPa or more), to see what kind of installation you are and use
- Q: What are the major brands of valves abroad?
- I say a few familiar: Tyco (the world's largest manufacturer of valves, the valve can provide almost all of it) Fuchs (a bit like, with the whole series of Tyco products)Blake (mainly butterfly valve, ball valve, chemical and water treatment applications up)Gaemi (diaphragm valve is doing very well) KSB (mainly in the power industry valve, globe valve, etc.)
- Q: What does the valve QF mean?
- Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
- Q: What are the ten major brands of China's valves?
- In the fluid piping system, the valve is the control element, its main function is to isolate the equipment and the piping system, regulates the flow, prevents the backflow, the adjustment and the excretion pressure. As the piping system selects the most suitable valve, it is important to understand the characteristics of the valve and the steps and the basis for selecting the valve. If you want to buy, you can choose the following aspects: 1. Select the valve according to the adjustment of medium parameters: two. According to prevent media backflow, choose the valve: three. According to the nature of the media, choose the valve. As for the brand if you can refer to the ten brands to buy China ten brands online, for example, Langao valve, a valve on the river, Amico, SF, card, open the valve on the market these are famous brands, you can refer to.
- Q: What's the valve as a unit?
- Generally used as a unit of measurement
