Flanged steel gate valve 31s16nzh Pn 100

Gate valves 31s16nzh PN 100  are steel wedge gate valves with a rising stem, used as shut-off devices on pipelines. They are designed for use in various industries, including oil and gas extraction and refining, power generation, and utilities.

Main construction elements

• Stem: The stem connects with the gate and the bonnet, ensuring a reliable connection. Its design allows for linear movement when the wheel is turned.
• Wedge: The wedge has a rigid construction and is responsible for blocking the flow of the working medium. It moves together with the stem, opening or closing the passage.
• Control: The valve is controlled manually using a wheel, allowing precise control of the gate position (open/closed).
• Flange connection: Connection to the pipeline is made using a flange method, which ensures ease of installation and removal.

Main areas of application for gate valves 31s16nzh include:

1. Oil and gas extraction and refining: The 31s16nzh valves are used to control the flow of liquids and gases such as oil, natural gas, and various petroleum products.
2. Power generation: In the energy sector, these valves are used to control the flow of steam and water in heat exchanger systems, boilers, and other installations where high tightness and reliability are required.
3. Utilities: In water supply and sewage systems, 31s16nzh valves are used to control the water supply and to shut off sections of pipelines for repair or maintenance.
4. Industry: These valves can be used in various industrial processes where the control of non-aggressive media flows is required.
