    AI Overview
    Forged Steel A105N Bellow Seal Globe Valves are high-pressure, durable valves designed for zero-leakage applications, commonly used in steam, hazardous, or toxic systems. Featuring an ASTM A105N forged carbon steel body and a welded metal bellows, they prevent stem emission losses and provide enhanced safety, often conforming to API 602 standards. 
    Key Features and Specifications 
    • Body Material: ASTM A105N (Normalized forged carbon steel).
    • Sealing Mechanism: Welded metal bellows (usually stainless steel) designed to prevent stem leakage, with a secondary backup packing.
    • Design Standard: Typically API 602, BS 5352, or DIN 3356.
    • Pressure Ratings: Class 150 to 1500 (or up to PN63).
    • Sizes: Commonly available from 1/2" to 2" (DN15 - DN50).
    • Ends: Socket Weld (SW), Threaded (NPT), or Flanged (RF).
    • Operation: Manual handwheel, usually with an Outside Screw and Yoke (OS&Y) design. 
    Common Applications 
    • Steam and Condensate Systems: Ideal due to high temperature/pressure resistance.
    • Hazardous/Toxic Fluids: Bellows prevent dangerous media from escaping through the packing.
    • High-Purity Media: Minimizes contamination risks.
    • Heat Transfer Oil: Excellent for thermal oil systems. 
    Benefits 
    • Zero Leakage: The main advantage over conventional packing-only valves.
    • Longer Service Life: Bellows reduces maintenance requirements.
    • Double Seal Design: Includes standard packing as a backup to the bellows. 
    Examples in the Market

    People also ask
    What is the difference between a globe valve and a bellow seal globe valve?
    The key difference is the sealing mechanism: a bellow seal globe valve uses a welded metal bellows that moves with the stem, eliminating the need for packing entirely. A conventional globe valve relies on graphite or PTFE packing around the stem — effective but subject to wear.Jan 23, 2025
