The WDL Valve WJ41H bellows seal globe valve is designed for steam pipelines,
\nboiler systems and high-temperature industrial applications. The bellows provides
\nreliable stem sealing and prevents external leakage of steam or process media.
\nThis design improves energy efficiency, operating safety and maintenance performance.<\/p>\n

The valve is available in PN16, PN25 and PN40 pressure classes, with nominal sizes
\nfrom DN15 to DN300. The final material selection and pressure-temperature limits
\nshall be confirmed according to the approved technical datasheet.<\/p>\n

Operating Principle<\/h2>\n

The WJ41H bellows seal globe valve uses a welded metal bellows as the primary stem
\nsealing element. A secondary packing seal provides additional protection if the
\nbellows is damaged. The bellows is welded to the stem to maintain stable operation
\nand reduce stem vibration caused by plug movement.<\/p>\n

Because the valve stem is isolated from the process medium, the WJ41H design
\nminimizes fugitive emissions and external leakage, especially in high-temperature
\nsteam service.<\/p>\n
