Features & Benefits
No Springs or Hinges
Free-floating ball eliminates springs, hinges, and guides that can corrode, fatigue, or clog in slurry and chemical service.
Self-Cleaning Ball Action
Ball rotation during each cycle presents a fresh seating surface and scours deposit buildup, maintaining consistent sealing.
Low Cracking Pressure
Precision-ground ball and low-friction seat provide cracking pressure as low as 0.05 bar, minimising pump energy consumption.
Sanitary Tri-Clamp Option
Tri-clamp end connections with Ra 0.8 µm finish available for pharmaceutical, biotech, and food-grade vertical risers.
Bidirectional Seat Option
Dual opposing seats allow ball to seal against either direction, accommodating oscillating or reversing vertical flow.
