Flanged Bellows Sealed Globe PN40

When handling high-pressure steam, thermal oils, or hazardous chemicals, there is no room for compromise. The Flanged Bellows Sealed Globe PN40 is engineered for precisely these conditions, a robust, 1-1/4 inch (DN32) flow control valve rated to 40 bar, built to start, stop, and regulate the most demanding fluid systems with complete confidence.

At the heart of its design is a welded metal inner bellows that flexes with every movement of the valve stem. Unlike conventional valves that rely on sliding packing rings which wear over time and risk fugitive emissions, the bellows assembly delivers absolute zero external stem leakage. For facilities handling toxic chemicals, high purity fluids, or vacuum service, this is not a marginal improvement; it is the difference between a safe system and a liability.

Installation is straightforward. Bolted flanged ends, manufactured to EN 1092-1 and equivalent standards, allow the valve to bolt directly into existing pipe systems, making maintenance and removal fast and reliable, no special tooling, no complicated procedures. The linear motion plug and disc configuration ensures both precise throttling control and tight, dependable shut off across the full range of operating conditions.

From boiler and steam systems to petrochemical plants and thermal oil circuits, the Flanged Bellows Sealed Globe PN40 delivers the kind of long-term, leak-free performance that industrial operations depend on.

Summary: 

• Specialised industrial flow-control device with a 1-1/4 inch (32 mm) nominal diameter, rated for pressures up to 40 bar
• Used to start, stop, and regulate fluids—such as high-pressure steam, thermal oils, or toxic chemicals—while completely preventing stem leakage and dangerous emissions
• Metric nominal size corresponding to a 1-1/4" pipe diameter
• Pressure rating meaning it is certified to safely handle up to 40 bar of working pressure
• Uses bolted, flanged ends (per standards like EN 1092-1) to bolt directly into industrial pipe systems for easy removal and maintenance
• Features a welded metal inner bellows that flexes with the valve stem instead of relying solely on sliding packing rings, achieving absolute zero external stem leakage
• Designed with a linear motion plug/disc configuration ideal for both tight shut-off and precise flow modulation (throttling)

Applications: 

Common applications include;

• Steam and boiler systems
• Thermal oil plants
• Chemical and petrochemical industries
• High purity and vaccuum service
