Needle valve
Needle valves are an important part of pipeline systems in the petrochemical industry, designed to control the flow of liquids and gases. A special feature of these valves is their ability to control the flow in a soft and controlled manner, so that they provide flexibility in the operation of the system.
The main working element is a cone-shaped needle, which allows for reliable and stable flow control, which is especially important in applications requiring high accuracy.
The needle valve is made of various materials depending on the properties of the working medium. In industry, it is used to regulate pressure and temperature in pipelines, as well as to control the flow rate.
