Kierreventtiilejä

Kierreventtiilejä, commonly known as threaded valves, are a type of valve used to control the flow of a fluid through a pipe. They are characterized by their threaded ends, which allow them to be screwed directly into a corresponding threaded fitting or pipe. This threaded connection provides a secure and relatively simple method of installation.

The primary function of a kierreventtiili is to regulate or stop the passage of liquids or gases. They achieve this through a variety of internal mechanisms, such as a gate, ball, or plug that is moved by a handwheel or lever. When the handwheel is turned, it actuates a stem that raises or lowers the internal sealing element, thus opening or closing the flow path.

Kierreventtiilejä are widely used in various applications, including plumbing systems for water and gas, industrial piping for chemicals and steam, and in HVAC systems. Their popularity stems from their ease of installation and relatively low cost. However, the threaded connection can be prone to leaks if not properly sealed with thread sealant or tape, and they may require more effort to operate than some other valve types. Disassembly for maintenance or repair can also be more challenging due to the threaded joint. Different types of kierreventtiilejä exist, such as screw-in gate valves, ball valves, and globe valves, each offering specific flow control characteristics and suitability for different pressure and temperature conditions.
