Ball valve

Progressive quarter-turn shut-off with bubble-tight seat

Specifications

The RFF ball valve provides a fast, positive quarter-turn shut-off. Its resilient elastomer seat design ensures tightness against both internal and atmospheric pressure, and its mirror-polished forged stainless steel ball withstands refrigerant abrasion. It is the ideal choice for continuous duty and throttling service.

Key features

  • 90° turn with resilient elastomer seat
  • Zero leakage Class A
  • Mirror-polished forged stainless steel ball
  • Anti-blowout stem
  • Quarter-turn operation, direct mount or via gearbox
