Stop valve
Shut-off valves – designed to shut off the working environment in the pipeline system. This class includes a large number of products that operate in the “closed-open” mode. Such an internal structure is explained by the optionality. Pipeline valves must provide two states of the structure – free and shut off. That is, an intermediate position is not provided in principle.
Application area of shut-off valves
Pipeline fittings are used in various areas of industry. Thus, they are indispensable in the field of:
- Air conditioning, ventilation and heating;
- Chemical and oil refining industries
- Nuclear energy
- Mining and metallurgy industry
- Food production
- Agriculture, etc.
One of the important characteristics that all types of shut-off valves must have is tightness. Only in this case can we talk about the possibility of completely blocking the flow of the working medium.
Classification and features
Shut-off valves are designed to work with such media as steam, gas, water, oil. As for the material, most often the products are made of brass, bronze, cast iron or stainless steel. Shut-off valves are classified according to several features:
- Method of overlapping;
- Scope of use;
- Method of control;
- The material it is made of;
- The amount of pressure that can be withstood;
- Installation method.
Depending on the area of application, shut-off valves are divided into industrial, general industrial, special, marine and plumbing. Industrial is the most popular, because it is used in the national economy and in production. General industrial is used in special conditions – low temperatures, high pressure, transportation of aggressive chemicals. Special shut-off valves are produced in limited quantities and by special order. Marine – on sea and river vessels. Plumbing – in everyday life. By the type of circulating working medium, shut-off valves are divided into power, cryogenic, steam-water, oil and ventilation. By the control method – flanged, coupling, welded and nipple.
