TECHNICAL DATA SHEET

Product Name: 3″ 150LB A105N Floating Ball Valve

  1. Product Description

This is a 3-inch, Class 150 floating ball valve constructed from A105N Carbon Steel. It is designed for general industrial applications, providing reliable on/off service in oil, gas, water, and process pipelines. The floating ball design ensures a tight seal by allowing line pressure to push the ball against the downstream seat. The valve is suitable for bi-directional flow shut-off.

  1. Caratteristiche principali
  • Floating Ball Design: The ball is not fixed; it floats between the seats. Upstream pressure forces the ball against the downstream seat, creating a tight seal.
  • Material: Body and major components made from ASTM A105N (Normalized Carbon Steel), offering good mechanical properties for a wide range of temperatures and pressures.
  • Classe di pressione: Designed to ASME Class 150 standards.
  • Blowout-Proof Stem: The stem is designed with an internal shoulder to prevent it from being ejected under line pressure.
  • Anti-Static Device (Optional): Available with springs and balls to ensure electrical continuity between the ball, stem, and body, preventing static charge accumulation.
  • Fire-Safe Design (Optional): Can be supplied with fire-safe certification to API 607 / API 6FA.
  • Low Operating Torque: Precision machined ball and seats ensure smooth and easy operation.
