OPERATING PRINCIPLE – MULTI-PORT FLOATING BALL

The valve operates through a precision-machined multi-port floating ball.

By rotating the ball 90Β°, the internal port alignment changes, enabling:

  • Flow diversion
  • Flow mixing
  • Line switching
  • Bypass control

Sealing is pressure-assisted through downstream seat loading, ensuring tight shut-off within rated pressure limits.

APPLICATIONS

Chemical Industry

  • Mixing systems
  • Dosing lines
  • Process diversion

Oil & Gas

  • Product transfer
  • Tank farm switching systems

Power Plants

  • Heat exchanger bypass
  • Cooling water changeover

Water & Infrastructure

  • Pump changeover
  • Flow distribution systems

THREE WAY VS FOUR WAY BALL VALVE – ENGINEERING COMPARISON

Feature Three Way Four Way
Port Type Application System Complexity
L / T Diverting / Mixing Moderate
Cross Port Reversing / Switching Higher
Installation Compact Requires system planning

Trunnion design is recommended for high-pressure, large-diameter, and torque-critical applications.

Four-way valves are selected for engineered switching applications.

AUTOMATION COMPATIBILITY

Available for:

  • β€’ Pneumatic Actuation
  • β€’ Electric Actuation
