Spherical Disc Butterfly Valves: Precision for Pharma & Chemical Processing
The Spherical Disc Butterfly Valve (often referred to as a Split Body or Pharma Butterfly Valve) features an investment-cast disc with a spherical seating surface. This unique geometry allows for a more consistent seal with lower friction compared to standard discs, ensuring a long working life and high performance in vacuum or pressurized conditions.
The FlowBiz Structural Advantage
- Forged & Fit Design: Engineered for minimal maintenance and maximum structural integrity.
- Bi-Directional Sealing: Provides a bubble-tight seal against pressure or vacuum up to PN10 / PN16 ratings.
- PTFE Soft Seat: The body is lined with a high-grade PTFE (Teflon) seat, enabling smooth operation at temperatures up to 210°C (Standard rating up to 180°C).
- Slim Seal Construction: The investment-cast "slim seal" wafer design minimizes the valve's footprint, making it ideal for compact pharmaceutical skids and powder handling systems.
