Product Overview
The HN69 Forged Steel Bellow Seal Globe/Gate Valve ANSI series is designed for compact high-pressure industrial pipeline applications where stem sealing reliability is important. The forged steel construction is suitable for small-bore ANSI valve requirements, while the bellow seal assembly helps reduce stem leakage risk compared with packing-only designs.
HN69 covers both globe valve and gate valve configurations within the same forged bellow seal product family. It is available from 1/2 inch to 3 inch, with Class 150 to Class 1500 pressure ratings. Connection options include butt-welded, socket-welded, threaded NPT and flanged configurations according to project requirements.
Typical applications include steam service, thermal oil systems, power engineering, chemical and petrochemical service, gas service and selected compatible industrial fluids. Final valve type, connection, pressure class, material grade and trim should be confirmed during quotation and drawing approval.
