Design - Ball valves have a chamber with a spherical ball that has a hole bored into it. The ball is connected to a handle, which increases or stops the flow.
Benefit - Ball valves allow the user to see exactly what position the valve is in. If the handle is perpendicular to the line, the hole is facing perpendicular to the line, and therefore is fully closed.
Application - Ball valves are used in high-pressure and shutoff applications, because they do not wear easily.
Design - Globe valves have a plate with a hole in it, and a disk or plug completely or partially fits into the hole, slowing or stopping flow.
Benefit - Globe valves offer greater precision than other valves when it comes to regulating flow.
Application - Globe valves are used in applications where flow needs to be finely tuned, they are designed to restrict flow.

The prosperity of the valve industry has been shown in many fields. Actually, there is great variety of the types of the valve. All these types are making their own contributions to the development of the whole modern industry. As we all know, Flanged Ball Valves are made to control the flow of gases, liquids and granular solids in many systems. In order to meet various requirements, valves are designed and manufactured with a wide range of the types, sizes, materials, working temperature and pressure and means of actuation and so on. At this moment, we take the type of the ball valve and gate valve out for a comparison. Learn more about flanged valves below.

The Overview of Long Pipeline Ball Valve
In the long pipeline system, the required pipeline ball valve must have the following functions such as controlling the medium, changing the direction of the medium flow, preventing reflux, cutting off the medium, blocking the pipe and so on.
In order to realize the above-mentioned functions, the long pipeline ball valve must be provided with the following features. Firstly, reliable sealability. The long-distance pipeline can only be checked at the regular time and sometimes it has to pass through high mountain, desert, grassland, earthquake region and other places. If the sealability is not good, it maybe will result in leakage or even the serious accident. Therefore, for preventing these things, this kind of valve must have the good sealability, especially for the sealiability of urgent grease injection. Secondly, the operation time should be long. Once the long pipeline ball valve is used, it can not stop working in several years or even in more than ten years. The longer it operates, the better it is. For prolong the service time, the valve seat is of great importance. Because to some degree it depends on the using time of the valve. Thirdly, the valve must have the high strength and resistance force. In the transportation process, the pressure of this valve may reach at 10.0MPa and the length may be very long. Therefore, it is easy to suffer the extending, curving or squeezing by the external forces such as earthquake, temperature or equipment vibration. In order to ensure the normal operation of the valve, enough strength is essential. Fourthly, the long pipeline ball valve should be resistant to corrosion. Because the natural gas contains the Hydrogen sulfide, which can erode the valve and eat the mechanical device, it is of great importance to select resistance-proof material. Fifthly, it has the automatic function. As we know, the long pipeline ball valve is controlled by the central control room. So in order to control the valve at the long distance immediately, the valve should be controlled automatically. Last but not least, the valve must be light in weight and tight in structure. With this feature, it is convenient to install and repair the valve.

Thus, leaking pipes are a hazard to your finances, surroundings and also to your safety. So, it is necessary to deal with such a situation as soon as possible.
The major causes of leaking pipes are due to break in the substance, increased water pressure or loss of bonding agents especially in the joints. Instead of looking for a professional assistance, in other words, a plumber; you should first try to fix the problem on your own. The first thing you need to do is to search for the source of the leak and then immediately turn off the water from the main valve. For temporary solution you can use quick fixes. You can also drape a piece of rubber around the leaking joint. After that apply a stainless-steel hose clamp. You must also drain water from the pipe by opening the valves below the leaks.
For leakage around fittings, dry the surface and measure the circumference of the pipeline. You can also make use of adhesives. They work efficiently and effectively on dry and clean surfaces. Apply the epoxy on both sides of the leakage. The various hardware parts that you can use to stop leakages are: Rubber lined sleeve clamp, hose clamps, quick fixes, duct tape or electrical tape, plumber epoxy putty. If you have all the right tools, then leaky pipes can be mended by yourself. Thus whenever you have to make any emergency repairs, you should have all the important and required materials by your side plus you should work carefully with hot water lines to avoid any sort of harm or burns.
Learning how to fix simple tasks will help you save money plus you will become skilled. If still the leakage prevails after trying all these remedies by yourself that means the leaking pipe might not be rectified. You should then call for professional help.
