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: What does the "XV" valve mean?
- XV:X said V is plug valve, said valve body material is chrome molybdenum vanadium steel.
- Q: What valves are needed on the construction site?
- Order valve flow1, customers have special requirements for products, must provide the following instructions in the contract: a) b) the length of the structure connection form C) nominal diameter, full size, shrinkage, pipe size d) using medium and temperature and pressure range E) test, inspection standards and other requirements.2, the factory can be configured according to customer specific requirements of various driving devices.3. If the customer provides the type and model of the valve to be determined, the customer shall correctly explain the meaning and requirements of the model and sign the contract on the condition that both the supply and demand sides agree.4, futures, order customers, please call the letter in detail to tell you the required valve model, specifications, quantity and delivery time, location, factory information, billing information, delivery address. And in accordance with the total amount of 20% of the predetermined amount or full amount of money, timely import our factory account, and the rest of the payment before shipment, import, in order to arrange delivery in time.

- Q: How do I open the gas valve?
- Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all. 1, according to the routine, now the handle position shows that the valve is open. 2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
- Q: What do you mean by the 16 bit coding of the valve type?
- What kind of coding do you mean? Valve type? Stress? Do you have these?Profit ZF43Y-250C-DN50.. Do you mean this one? ZF43Y valve type. Flat gate valve250C. Refers to the 250 pressure, C is carbon steel, DN50 refers to the caliber of the valve specificationsI hope you mean this one
- Q: Which valves are installed in a directional manner?
- Regulating valve, stop valve, eccentric butterfly valve, check valve, one-way valve, solenoid valve, pressure reducing valve, drain valve and drain valve. Needle core valve, V ball valve, part of the ball valve, there is flow.Few. Such as floating ball valve, the central butterfly valve does not flow requirements. In general, if the regular manufacturers of valves, flow direction will indicate the flow of medium, to get the valve can see.
- Q: How do you calculate the flow of the valve?
- Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
- Q: What are the most common types of valves?
- Gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, drain valve, plug valve, throttle valve, plunger valve, diaphragm valve, relief valve, foot valve, drain valve etc.
