Description
ND 40 Globe Valve - DIN/EN Standard PN40 High-Pressure Flow Control
FlowBiz Exports is a leading manufacturer and exporter of DIN-standard ND 40 Globe Valves (Nominal Pressure PN40). Designed in full compliance with European EN and DIN engineering standards, these heavy-duty valves deliver superior flow regulation, precise throttling, and bi-directional tight shut-off in high-pressure steam, thermal oil, chemical, and industrial fluid processing pipelines.
Key Features & Operational Superiority
- DIN / EN Standard Compliance: Engineered to DIN 3356 and EN 13709 specifications, ensuring exact face-to-face dimensions (EN 558-1 Series 1) and full interchangeability in European piping networks.
- Precise Throttling Capability: Streamlined seat-and-plug geometry allows stable flow regulation, accurate pressure drop management, and minimal seat erosion under throttling conditions.
- Rising Stem with OS&Y Yoke: Outside screw design protects trapezoidal stem threads from fluid contamination while providing clear visual position indication.
- High-Integrity Bonnet Sealing: Fitted with spiral-wound graphite gaskets and deep packing boxes to eliminate stem fugitive emissions under thermal cycling and pressure fluctuations.
