Flanged cast stainless steel gate valves 30nzh64nz with rising stem PN 25 are shut-off valves designed to work with aggressive media, including chemical solutions and other substances that can cause corrosion of ordinary materials.
Marking
- 30 – denotes the type of product (gate valve).
- nzh – indicates the body material (stainless steel).
- 64 – model code according to the nomenclature.
- nzh – means that the seal is made of stainless steel.
Design features
- Gate valve 30nzh64nz belongs to cast shut-off valves with a wedge gate. The wedge gate blocks the flow of the medium perpendicularly to direction of the working medium's movement.
- Manual operation is carried out through wheel. When the wheel is turned, the torque is transmitted to the stem, which raises or lowers the wedge, opening or closing the passage section.
- Stem extends when the valve is opened, which requires additional height space during installation.
- Gate valve has a flanged connection.
Gate valves 30nzh64nz are widely used in the following industries:
- Oil and Gas Industry: For controlling the flow of oil, gas, and oil products.
- Chemical Industry: For handling aggressive chemical substances.
- Energy Sector: Used in steam lines of power plants.
- Water Supply and Sewerage: For controlling water flows.
- Metallurgy: On production lines with high temperatures.
- Shipbuilding: For water or fuel supply systems on ships.
- Food Industry: For transporting liquids or gases neutral to the valve materials.
