  1. Features
  1. Bidirectional Sealing – The floating ball is pressed against the downstream seat by line pressure, providing tight shut‑off with no flow direction restriction.
  2. Fire‑Safe Design (Optional) – Anti‑static design available; fire‑safe configuration with graphite backup seat meets API 607 / API 6FA.
  3. Blow‑out Proof Stem – Stem is inserted from inside the body with a backseat to prevent blowout under sudden pressure surges.
  4. Low Operating Torque – Precisely machined ball and seat offer low friction, quick quarter‑turn operation, and reduced torque.
