Stamp-welded gate valve 30s547nzh, 30s947nzh for manual or electric actuator Pn 4

Stamping and welding gate valves 30s547nzh, 30s947nzh for manual or electric actuator PN 4 are designed to control flow of various working media in pipelines with low pressure. They differ from cast analogues in the manufacturing technology - body parts are made by stamping and welding, which makes them lighter and cheaper.

Construction

• Body: Made of steel by stamping and welding.
• Wedge: The locking element that blocks the passage of the pipeline.
• Spindle: Used to transmit force from the drive to the wedge. In gate valves 30s547nzh, 30s947nzh the spindle is rising, which means that when the valve is opened, the spindle rises above the body.
• Sealing surfaces: Ensure the tightness of the gate. In these valves, they are made of stainless steel, which increases their corrosion resistance and durability.

Advantages of stamping and welding gate valves

• Lighter weight: Compared to cast analogues, which simplifies installation and transportation.
• Relatively low cost: Due to the simpler manufacturing technology.
• Maintenability: The design allows individual parts to be replaced.

Applications

• Water supply and sewage systems.
• Heat networks.
• Oil and gas industry.
• Chemical industry (for non-aggressive media).
• Other industries where reliable flow shut-off of the working medium is required at low pressure.
