Steel gate valves 30s41nzh with a rising stem PN 16 are used in pipeline systems to shut off the flow of various working media, such as water, steam, oils, petroleum products, and other non-aggressive media at temperatures up to 425°C. Gate valves 30s41nzh are widely popular due to their ability to work with a wide range of working media and their relatively low cost.
Marking
- 30 – denotes the type of product (gate valve).
- s – indicates the material of the body (steel).
- 41 – model code according to the nomenclature.
- nzh – means that the seal is made of stainless steel.
Structural 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.
Gate: Made in a double-disc design.
Sealing surfaces: To ensure tightness, sealing rings made of stainless steel are used.
Stem and wheel: The wheel transmits rotary motion through the stem, which converts it into the translational movement of the gate.
Flanged design: Thanks to the flanged connection, installation is carried out without welding, which allows the product to be easily installed and dismantled, as well as serviced.
Areas of application
- Oil and gas pipelines. Gate valve 30s41nzh is widely used in the oil and gas sector for transporting oil, petroleum products, and natural gas. It is in these systems that complete flow shut-off is ensured, which is crucial for safety and leak prevention.
- Water supply systems and steam lines. In addition to the oil sector, the gate valve is used for working with hot and cold water, as well as for steam transportation, due to its high-temperature resistance (operating range from -40°C to +425°C).
- Industrial installations. The device can be used in various buildings and industrial sites where a reliable and durable locking device is required.
Gate valves 30s41nzh Premium feature improved build quality and extended service life. Unlike standard versions, these valves are equipped with a stem made of SS420 (20X13) stainless steel, which provides enhanced corrosion resistance and durability. In addition, upgraded brass bushings and sealing elements are used, ensuring tighter contact of the sealing surfaces and improved tightness. This reduces wear, minimizes the risk of leakage, and increases the overall lifespan of the valve.
These design improvements make this version more reliable compared to standard 30s41nzh gate valves.
