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 a lift rod valve?
- The valve stem and valve plate are relatively fixed, and the valve stem rises up when the valve plate is raised
- Q: I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?
- From the appearance of it is not too good to say, if it is the valve, only one-way valve.The valve usually consists of the stem, spool, seat, body, seal, and so on. This figure feels more like a filter that connects a pressure vessel to an inlet or an inlet.I've seen a lot of filters like this, usually open with -drain filter inside. Play a role in the filter of some large magazines, you can change, more metal, the mother is relatively small (relatively large hole)
- Q: What does the J41Y-100I valve type mean?
- J41Y-100I flange type chrome molybdenum steel valve forgingJ represents the cut-off valve, 4 (flange) on behalf of his connections, 1 (straight) on behalf of his structure, Y (seal) on behalf of his seat sealing surface or liner material code, 100 is the nominal pressure value, I (chrome molybdenum steel) is the code of the body material
- Q: What does the valve stroke mean?
- The distance from one position to another. Usually in the first position of the cut position, the second position is put through the position. Unless the valve has 3 positions.
- Q: A kitchen, 2 bathrooms, in addition to the toilet, toilet (only cold water), the rest need hot and cold water supply, and hot water by solar water heaters and gas water heater selection. The kitchen is mainly a sink, each toilet for toilet, shower, washbasin, separate cold water faucet. I don't know how many metal materials I'll use now Thank youThe waterways are all dark!
- PP-R ball valve (cold hot water pipe valve): solar water heater 2, gas water heater 2, 2 hot water pipe switching with 1, indoor main water supply valve 1, 2 toilet water supply valve 1, total 8.Eight character valve (angle valve): kitchen, dishes, basins 2, toilet, toilet 2, wash basin 4, total 8.Other: shower water mixing valve 2, water washing machine 2, 2 washbasin faucet, basin faucet dish 1.The water supply of solar water heater and gas water heater is calculated according to the hard connection of PP-R pipe.
- Q: What courses in the University involve valves?
- Fluid mechanics, "material mechanics", "mechanical design" and other courses on the design of the valve are helpful.
- Q: According to the original valve installed on it, but never demolished, I am afraid to force over, will not be broken? The old valve, that part of the remaining three tubes tight.
- Look, the valve you bought looks like PVC hot melt.. If the old valve and the elbow must be rejected with a hacksaw, hot melt and buy a new elbow and PVC section pipe for hot melt machine welding. From the picture didn't see traces of the thread,
- Q: How to check the quality of the valve?
- First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level. Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem. Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.
- Q: What is a heavy body valve?
- You should be asking what a heavy-duty valve is.This is only in the ordinary gate valve and cut-off valve on the distinction. Nowadays, ordinary gate valves and cut-off valves are divided into heavy-duty ones. Medium and light three kinds ~!
- 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.
