Ductile Iron Y-Type Strainer for Water Systems
Release time:2025.09.05
Ductile Iron Y-Type Strainer for Water Systems | Large Flow Area, Low Resistance
Juhan’s ductile iron Y-type strainer is engineered for modern water systems. It complies with GB/T41681-2022 and adopts a 4× flow-channel screen design to maximize throughput and minimize head loss. Based on years of field feedback, the bonnet has been re-engineered with a flow-blocking feature to mitigate turbulence-induced abrasion, and a pre-reserved blow-off port simplifies bypass/drain installation. The screen uses Stainless Steel 304 for durability and corrosion resistance.
Key Technical Features
- 4× larger flow channel screen → bigger effective area, lower resistance coefficient.
- Anti-erosion bonnet with flow-blocking design reduces long-term wear from disturbed flow.
- Pre-reserved blow-off port for quick drain or bypass piping.
- SS304 screen for strength, hygiene, and service life.
- Optimized internal geometry → smoother flow path and less clogging risk.

Benefits at a Glance
Engineered for Water System Reliability
In water and HVAC systems, strainers protect downstream valves, meters, and equipment from debris. By expanding the screen’s effective flow area and optimizing internal flow paths, Juhan’s Y-type strainer sustains capacity while keeping pressure drops low. The SS304 mesh maintains structural integrity under continuous service, and the bonnet’s flow-blocking design tackles the root cause of turbulence wear—extending lifecycle and reducing unplanned downtime.
For engineers and contractors, the pre-reserved blow-off port simplifies routine purging and bypass piping. Whether it’s a municipal water loop, a central air-conditioning circuit, or a water treatment skid, the strainer integrates easily and keeps systems running clean and efficient.
FAQs
Does the fluid contact the metal body?
No. The internal design and SS304 screen ensure the medium primarily interfaces with corrosion-resistant surfaces, minimizing contact with the ductile iron body and reducing rust risk.
What’s the advantage of the 4× flow-channel screen?
It increases open area, lowers the flow resistance coefficient, and sustains higher flow at comparable pressure drops.
Where is it typically used?
Water supply and drainage lines, central air-conditioning (HVAC) loops, and water treatment equipment.
Compliance & Quality Control
Each unit is manufactured under strict process control and inspected against GB/T41681-2022. Performance validation covers pressure integrity, screen integrity, and flow resistance to ensure consistent results in real-world service.
