Three-Way Filtration

Definition: A filtration system that allows fluid to be directed through one of three selectable flow paths, typically via a three-way valve. It is used to control how a liquid is filtered, bypassed, or circulated.

Operation:

  • Primary filtration mode – Fluid passes through the filter element to remove contaminants.
  • Bypass mode – Fluid is diverted around the filter for maintenance or emergency operation.
  • Recirculation mode – Fluid is returned to the source tank for continuous cleaning without delivery to the process.

Features:

  • Single housing with a three-way valve or manifold
  • Designed for quick changeover between modes
  • Suitable for various filter media (cartridge, bag, mesh)
  • Often fitted with pressure gauges for monitoring

Advantages:

  • Continuous operation during filter servicing
  • Flexibility in system operation
  • Reduced downtime and process disruption

Applications:

Lubrication systems, hydraulic systems, fuel handling, chemical processing, water treatment.
