Ball valves for welding for heat supply.

The ball valve for welding is a shut—off and control valve, which is designed for installation in engineering systems transporting liquid or gas working media.

The all-welded ball valve for welding is used in the industrial and household sphere. Their use is common in heat supply systems, water supply systems involved in oil refining or the food industry. Welding is used as an installation method, which ensures maximum reliability of the connection.

Full-bore ball valve for welding. Differences.

The ball valve for welding with a handle has two-stroke control. One position provides an open position of the ball-gate with a hole through which the liquid passes, the other — closed. It is necessary to avoid intermediate positions of the handle, as this leads to wear of the mechanism. The simplicity of the design makes it easy to operate mechanically without additional devices.

The all-welded ball valve for welding is made of stainless materials, which guarantees the wear resistance and strength of the reinforcement. Carbon or stainless steel with a high content of manganese, titanium and chromium are often used, which increase the resistance of the device to external and internal aggressive influences. In addition to steel, brass, iron and bronze are used.

Varieties of ball valves for welding.

The ball valve for welding has several varieties, which are due to design differences.

There are standard-bore and full-bore ball valves. Their main difference lies in the throughput, as well as in the presence of a narrowing of the diameter of the holes in the pipes.

The difference between screens with a standard pass and a full one explains the difference in application. Standard-bore cranes are small in size and are suitable for systems where there is no high pressure. For example, on the branches of pipelines. They protect the engineering system from water strikes. Full-bore ball valves are required on highways where the hydraulic resistance of the working medium needs to be reduced.

The type of handle is also an important criterion. Valves are direct-flow, flow-through and mixing.
