Today the market is oozing with ball valves options: the variety of modifications is suitable for virtually any industry or household, and if it is not, you can always take advantage of a custom solution. Each of them corresponds to different requirements designed to work with certain operating environments at a certain pressure and temperature conditions. Therefore, when making a choice you should keep in mind a number of aspects.
Classification of ball valves and installation method
A method of mounting the ball valve to the pipe is different. Each of them is acceptable under certain conditions.
Ball valve thimble
Ball valves thimble is most often used for water, gas pipelines and heating systems in residential and public buildings. They are reliable, practical and and easy to install and use. Ball valves coupling easy to install and remove without the use of special equipment. Grooved ball valve should be used to mount the pipe in diametral section which does not exceed 40-45 mm. To make better use of overall pipe flanged ball valves are utilised.
Ball valve flanges
Flanged ball valve is used for installation in pipes with diameters greater than 45-50 mm. Using mounting seals ensures high integrity and strength of the connection of the ball valve and the pipe. Flanged ball valves have a high strength and designed for heavy loads.
Flanged ball valves can have:
- cast housing;
- housing, consisting of 2 parts that can be easily disassembled to replace damaged parts (e.g., gaskets or locking elements) in case of breakage.
Flanged ball valves are ideal for piping work environment – e.g. oil or gas.
Choke ball valves
This type of equipment is also widely used in chemical, food and other industries. Reusability disassembly make such ball valves convenient in operation.
Weld ball valves
These devices in contrast to the choke or flange ones should better not be installed in places where quick removal or repair are not possible. Thus, it is preferably to use these devices in closed places, where dismantling is not provided. Weld ball valve is installed by welding, so performed solely by specialists. The most commonly welded ball valves are used in construction.
Combined ball valve
Some manufacturers produce a combined ball valves, standing out from all the rest types with a different attachment mechanisms. Classification by the number of nozzles:
- angled ball valves
- communicating Ball Valves
- Three-way ball valves
- multi-way ball valves
Three-way ball valves are used for routing and mixing environments. Ball valves are practical and they are very compact, which plays an important aesthetic role. They are easy to operate – easy turning the lever by 90° allows you to instantly block access to the working environment, which is especially important for sudden ‘accidents’ such as leaking water pipe or a gas leak.
Quality ball valves by solid manufacturers, such as Orseal, focusing on ball valves and industrial ball valves solutions, are wear-resistant, made of materials resistant to corrosion and coping with the impact of aggressive media easily. Ball valves are easy to repair, and are low cost compared to other valves of the destination. All these advantages give ball valves the leadership status.
