Flanged and butt-welded connection options with ISO 5210 actuator-ready design. Suitable for steam, petrochemical, oil and gas applications.

SKU: HN70-BSGG-ANSI Categories: , , ,

Product Overview

The HN70 Bellow Seal Globe/Gate Valve ANSI series covers larger ANSI class-rated bellow seal valve configurations for industrial pipeline service. It is available as globe valve or gate valve configurations, with flanged or butt-welded end connections and pressure classes from Class 150 to Class 1500.

HN70 is intended for applications where improved stem sealing reliability and reduced fugitive emission risk are important, such as steam systems, oil and gas pipelines, petrochemical plants, chemical processing, power engineering and general industrial service. The bellow seal assembly works together with secondary packing to help contain media around the stem area under compatible operating conditions.

Final configuration should be selected according to valve type, size, pressure class, body material, end connection, operation method and project documentation requirements.

Key Features

  • ANSI class-rated bellow seal globe and gate valve series.
  • Size range: 2 inch to 16 inch.
  • Pressure classes: Class 150, Class 300, Class 600, Class 900 and Class 1500.
  • Flanged ends according to ANSI/ASME B16.5.
  • Butt-welded ends according to ANSI/ASME B16.25.
  • Gate valve design reference: API 600.
  • Globe valve design reference: BS 1873.
  • Face-to-face reference: ANSI/ASME B16.10.
  • Manual handwheel operation as standard; electric actuator options can be discussed based on project requirements.
  • Secondary graphite packing provides backup stem sealing support if the bellow assembly is damaged.
