Y Type Strainer
1. Product Overview
Y-strainers are compact filtration devices designed to protect downstream equipment by mechanically removing particulates from liquid, gas, or steam systems. The distinctive "Y" shape design provides optimal flow characteristics while allowing easy maintenance.
Key Advantages
✔ High Dirt-Holding Capacity - 3-5x more than basket strainers
✔ Low Pressure Drop - Optimized flow path design (Kv=0.6-1.2)
✔ Compact Design - 30% smaller footprint than T-type strainers
✔ Multi-Purpose - Suitable for liquids, gases, and steam
✔ Maintenance-Friendly - Blowdown valve optional for inline cleaning
