Flanged steel gate valve 30s64nzh Pn 25

Steel gate valves 30s64nzh with a rising stem PN 25 are used for complete shut off flow of the working media such as water, steam, oil and other non-aggressive liquids or gases.

Marking

• 30 – indicates the type of product (gate valve).
• s – indicates the material of the body (steel).
• 64 – model code according to the nomenclature.
• nzh – indicates that the seal is made of stainless steel.

Design features and main elements

Body: Made by casting from carbon steel. The cast body ensures sufficient mechanical strength and corrosion resistance when used with non-aggressive working media.

Shutoff element: The shutoff element is a two-disc wedge attached to the stem and positioned perpendicular to the flow axis. The flow is shut off by moving the wedge up or down relative to the passage holes in the body.

Control: The valve is manually operated using a handwheel. When the handwheel is turned, the stem moves in a linear motion along with the attached wedge.

Rising stem: The design includes a rising stem, which increases the building height of the valve in the open position by the amount of gate travel.

Connection to the pipeline: The valve is installed on pipelines using a flanged connection.

Main application areas of 30s64nzh valves include:

1. Industry: 30s64nzh valves are used in water supply and heating systems where it is necessary to control the flow of water and steam. They can be used for both cold and hot water, making them versatile for various industrial processes.
2. Oil and gas industry: These valves are also used in the oil and gas extraction and processing industries, where they are used to control the flow of oil and petroleum products. Their ability to operate at high temperatures (up to +425°C) makes them ideal for such conditions.
3. Chemical industry: 30s64nzh valves can be used for transporting chemical media that are not aggressive to the materials of the valve construction. This allows them to be used in various chemical processes.
4. Heating systems: In heating systems, these valves provide reliable control of the flow of the heat carrier, which is critical for maintaining system efficiency.
