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 LBC mean in a valve?
- LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.
- Q: What is the normal temperature on the valve?
- 3. classification by operating temperature(1): ultra-low temperature valve for medium temperature of t< DEG C; 101 valve.(2): used for medium temperature valve operating temperature 101 C = t = 29 C valve.(3) at room temperature for medium temperature valve: the valve 29 <t<120 DEG C.(4) the temperature valve for medium temperature 120 = t = 425 DEG C valve(5) high temperature valve: valve used for medium temperature t>425 degrees celsius.If it helps, see it
- Q: How about the valve?
- In 1998 began the formal production of valves. As the company expanded in size, in September 2003, changed its name to the British HV VALVES LIMITED (HUDDERSFIELD), referred to as the United kingdom. The design and production of various types of valves, widely used in power, oil, chemical, offshore platforms and other fields, with its excellent quality and service to win the praise of the vast numbers of users.
- Q: Where is the hydrant main valve?
- The intake valve of the upper and lower ring pipes of the riser of the fire hydrant is generally located at the highest and lowest floors.The general use of the valve rod flange gate valve.Hydrants, officially called fire hydrants, are a type of fixed fire fighting facilities, which control fuel, insulate fire and eliminate fire. Indoor fire hydrant and outdoor hydrant. The fire fighting system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler system, water gun system, gas fire extinguishing system, fire detection system, water mist system and so on. Fire hydrant mainly for fire engines from the municipal water supply network or outdoor fire water network to implement fire fighting, can also be directly connected to the hose, water gun fire extinguishing. Therefore, indoor and outdoor fire hydrant system is also one of the important fire fighting facilities.
- Q: What does the J41Y-100I valve type mean?
- Stop valve typeJ 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 3/4''mean in the name of the valve?
- 3/4''is the valve diameter, said 20MM, inches, equivalent to DN20 of the valve, is also said to be the 6 interface we say old foreman
- Q: What kind of industry does valve belong to?
- Valves are machinery and industry equipment；Valve belongs to general mechanical equipment
- Q: What are the general types of valves?
- Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion. In addition to the cylinder or hydraulic cylinder piston to drive, but also the use of pneumatic film driven, because of its small stroke and driving force, it is mainly used for regulating valves.Manual valveThe manual valve is the most basic way of driving the valve. The utility model comprises a hand wheel, a handle or a plate hand, and is driven directly and driven by a transmission mechanism two kinds. When the starting torque of the valve is large, it can be driven by gear or worm gear to achieve the purpose of omitting. Gear drive, spur gear drive and bevel gear drive. Gear reduction ratio is small, suitable for gate valve and stop valve, worm gear drive is relatively slow, suitable for cock flashing, ball valve and butterfly valve
- Q: How can the material be checked by valve approach? What experiments do you need?
- May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.
- Q: Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
- The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
