Flanged steel gate valve 30s76nzh Pn 64

Steel gate valves 30s76nzh with an outside screw stem PN 64 are used for completely shutting off the flow of working media, such as water, steam, oil, oils, natural gas, and other non-aggressive liquids or gases.

Marking

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

Structural features and main elements

Body: Made by casting carbon steel. Ensures strength and resistance to high temperature and pressure.

Shut-off element: The shut-off element is a double-disc wedge that moves up or down the stem when the gate valve is opened or closed. This allows for effective shut-off or opening of the working medium flow.

Stem: The stem is made of corrosion-resistant steel and has an outside screw construction, which increases the building height of the gate valve in the open position by the amount of the shutter stroke. It is operated manually with the help of a handwheel.

Connection to pipeline: The gate valve is installed on pipelines using a flange connection.

Main applications of 30s76nzh gate valves include:

1. Industry: Used in the oil and gas industry, at processing and transportation facilities for hydrocarbons, where reliable protection against leaks is required.
2. Utility services: Applied in water supply and drainage systems, as well as in heating and steam systems, where effective shut-off of the working medium flow is needed.
3. Energy sector: Used on pipelines where steam and other working media with high flow rates are transported, due to the low hydraulic resistance of the design.
