ARI-STOBU® Globe Valve DN 50 PN 25

ARI-STOBU® Globe Valve DN 50 PN 25: Reliable Flow Control in High Pressure Installations

ARI-Armaturen , based in Germany, industrial valves and It is a world-renowned brand for faucets. ARI-STOBU® Globe Valve DN 50 PN 25 is a high-performance valve designed to precisely control, cut off or regulate the flow of fluids (water, steam, gas, oil, etc.) in industrial processes. This model offers reliability and long life, especially in medium-high pressure systems. DN@ 50 (Nominal Diameter 50 mm / 6 inç) size indicates that the valve is suitable for use in large-scale lines, while PN 25 (25 bar) pressure class indicates that it can operate safely up to 25 bar nominal pressure. specifies.

ARI-STOBU® What is a Globe Valve and How Does It Work?
Glob valves are devices that control the passage of the fluid with a linear movement, that is, by opening and opening the flow by rising and falling of the disc on the seating surface (sit) in the valve body. These are valves that close or adjust. ARI-STOBU® series stands out with its optimized flow path and robust structure.

Globe Valve Technical Specifications:
Fig. 23.306 PN25: This figure and the PN code specify the specific design and pressure class details of the valve.
Body Material: EN-JS1049 Ductile Iron (GGG-40.3): Ductile iron, standard gray cast It offers much higher tensile strength, impact toughness and compressive strength than iron. This ensures the valve has superior resistance to harsh industrial conditions.
Cover Material: EN-JS1049 Ductile Iron (GGG-40.3): Manufactured from the same durable material as the body, ensuring reliability under high pressure and temperature
Clapper Material: CuZn35Ni3Mn2AlPb (Aluminum Bronze / Copper Alloy): This special copper alloy offers excellent resistance to corrosion, erosion and abrasion. It provides high performance especially in sea water, steam and certain chemical fluids.

ARI-STOBU® Highlights and Advantages of Globe Valve:
Precision Flow Control: Fluid due to the inherent nature of globe valves. The flow rate can be adjusted very precisely. Ideal for modulating (partial opening and closing) control with conical or parabolic flap options.
High Pressure Resistance (PN25): bar being resistant to working pressure makes the valve suitable for applications requiring medium-high pressure.
Durable and Sturdy Structure: Ductile iron body and cover and special alloy valve provide long-lasting and reliable operation.
Low Pressure Loss: Thanks to the optimized internal flow path, minimum pressure loss in fluid passage.
Ease of Maintenance: Access and maintenance of the internal parts is generally practical thanks to the easily removable cover design.
Wide Operating Temperature Range: Thanks to the combination of materials used, it can be used in a wide temperature range (usually from -10°C). It can be used safely up to +350°C (varies depending on the flap material).
Compliance with International Standards: EN They are produced in accordance with standards such as 13789.

@@ ARI-STOBU® Glob Valve Usage Areas:
ARI-STOBU® Globe Valves are widely used in medium-large scale industrial applications where precise flow control and durability are important:
Steam and Condensate Lines: Steam distribution lines, heat exchangers, steam boilers.
Heating and Cooling (HVAC) Systems: Water and steam control in central heating and cooling systems.
Industrial Processes: Control of water, oil, gas and certain chemical fluids.
Marine Applications: Seawater lines requiring corrosion resistance (thanks to clapper material).
