Valves: types and purpose

When designing pipelines by using various shut-off elements. To correctly select the rebar you need to understand the purpose and features of operation of each type. To simplify your choice and to save time we have prepared useful material on the subject. After reading you can easily find the most suitable for the specific task elements of the pipeline on the website https://anica.by/ company "Anika-invest".

Where applicable valves?

The locking elements are among the most popular on the market of valves for pipeline. They are used extensively in the organization of water pipelines in residential buildings, domestic and industrial premises, transport of piped gas and are indispensable in the construction of sewage removal. Heat is also not complete without this kind of reinforcement.

Note the shut-off elements for special pipelines transporting aggressive or just reactive environment. Such devices are made from neutral or resistant to chemicals and metal alloys. Products are resistant to corrosion and, most of all, can withstand more pressure than valves for water, protruberant. The main field of application: cosmetics, chemical, food industry, processing of petroleum products.

Various types of valves

There are four types of valves:

• cranes;
• the valve;
• valves (control valves);
• flap.

Valves are typically ball or cork locking element. They are used in pipelines transporting water, steam, gas. They have little resistance and are widely used in everyday life. Shut-off valves are regulated by a handwheel or actuator. It is possible to configure remote management. Such valves made of various materials: from plastic to cast iron. Installation is carried out by means of couplings. The largest use of valves received in systems of industrial pipelines, and water, steam, air ducts.

Valves may have a diameter up to 220 cm and can effectively be operated at pressures up to 1 MPa. Basic materials — iron, steel. The flaps are easy to control, high reliability, low cost of operation. Gate valves differ from the rest of the valves by the presence of spindle. It can be sliding and non-sliding. The main applications — transportation of coke, fuel gas, petroleum products.
