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 it installed, what is the role, what is the material, and are there other alternatives instead of this effect?
- Main stem to prevent leakage, there are PTFE and graphite and so on. There are no other good products to replace.
- Q:G what's the meaning of the valve?
- G is the diaphragm valve, valve type code, there are other types of valve code.A D is a safety valve, butterfly valve, check valve (H valve), J is the cut-off valve, throttle valve is L, P is Q is the drain valve, ball valve, S trap, U X is a plunger valve, plug valve, Y valve, Z valve.
- Q:How about the valve?
- The British Hudson Valve Co. Ltd. (HUDDERSFIELD VALVES LIMITED), founded in 1964, its predecessor for the British metal parts company (ART METAL FABRICATION LTD AMF, referred to as LTD), located in the world famous one of the UK's Huddersfield valve production center (HUDDERSFIELD), the main production of various kinds of valve, valve cage valve and other valve manufacturers supporting. .
- Q:The general signal valve installation, or other valve installation is not installed with the groove flange clamp hoop Yucca or direct way? What's the convenient way to install the following diagram? I don't understand. Neither groove, flange nor hoop. Thank you, sir!
- The blue one is the separate body, and the red one is the welded flange on the pipe. There is rubber on the valve body, and it can be sealed with flange. This is determined by the structure of the butterfly valve, usually DN150 of the small diameter butterfly valve are installed this way. It comes with flanges, but the prices are much higher. Small caliber general butterfly valve is generally used for low pressure, leakage requirements are not high, so rarely use its own flange. With flanges, it is generally used in petrochemical systems and has a much higher pressure level.
- 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:Ketem valve relative to other valve companies in the industry what are the advantages?
- Floating seal: electric drive, electric ball valve flange connection floating ball straight, seal form with seal, the sealing surface of the valve seat material for hard alloy, nominal pressure PN16~PN63, nominal size DN15~DN200, suitable temperature of -28~500, the valve body is made of carbon steel or stainless steel. As a result of the use of hard sealing (metal seal), this valve is particularly suitable for particles, solids, slurry and other medium and high temperature and high pressure pipelines.
- Q:What are the definitions of internal, external and leakage valves?
- Upstairs to say there is a problem. The leakage within the valve that is the reason of erosion wear medium makes the valve is not closed tightly, even if the valve screw (stem) screwed in place, because there is still a gap between the spool and the valve body, the medium can flow past. Outside leakage generally refers to the valve and connecting flange or threaded connection between the seal and guide...
- Q:There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature
- The valve has a device resembling a cylinder lock without a dedicated key. However, your home heating is not hot, the valve does not have much relationship. As long as the hole on the valve is parallel to the pipe, the valve is fully open.
- Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise
- It should be said that the diameter is represented by units per inch! 15mm 6mm nominal diameter valves representing metric units!
- Q:Is the filter also valve?
- Filters are generally used in the pipeline, are ancillary products, strictly divided, it does not belong to the valve category
