Working Principle
The Y strainer protects piping systems by trapping contaminants before they reach sensitive equipment.
Flow Process
- Fluid enters the inlet.
- Contaminants are captured by the stainless steel screen.
- Clean fluid exits through the outlet.
- Accumulated debris can be removed periodically through the cleanout plug.
This simple yet effective design minimizes maintenance and improves system reliability.
