Product Description
The Ductile Iron Y-type Strainer with an SS304 screen is engineered for high-efficiency filtration in water supply pump inlet pipelines and various industrial fluid systems. Designed to intercept solid impurities, debris, and particulates, this strainer plays a critical role in protecting downstream valves and equipment from damage or clogging. With a robust ductile iron body and a precision-crafted stainless steel filter screen, it ensures long-term operational stability, making it an essential component for municipal water supply, HVAC systems, and industrial fluid management.
Our Y-type strainers are manufactured and tested to meet stringent industrial standards, ensuring reliable performance and easy integration into your existing pipeline infrastructure.
Flange Connection Standards: Complying with GB/T17241.1-2024 and GB/T 9124.1-2019, the flanged ends guarantee precise alignment and secure installation. This compliance minimizes the risk of leakage at connection points and reduces installation time for engineering projects.
Strength and Sealing Tests: Every unit undergoes rigorous pressure and sealing tests in accordance with GB/T13927-2022. This strict quality control ensures the structural integrity of the ductile iron body and the reliability of the sealing rings under continuous operational pressure.
Comprehensive Specifications: Relevant technical parameters are detailed in Table 1, main component materials in Table 2, and overall dimensions in Table 3. These specifications provide clear guidance for accurate product selection based on your system's pressure and size requirements.

The materials selected for this Y-strainer are focused on maximizing durability and operational safety. The body and bonnet are constructed from high-quality ductile iron, offering superior tensile strength and impact resistance compared to standard cast iron. This ensures the strainer can safely handle pressure fluctuations in water supply systems. The sealing rings, available in NBR or EPDM, provide excellent resilience and chemical compatibility, ensuring a watertight seal across the designated temperature range. Furthermore, the use of carbon steel fasteners ensures structural stability under high-pressure conditions.

Robust Double-Layer Stainless Steel Mesh: The core filtration component utilizes a double-layer stainless steel (SS304) mesh structure. This design provides exceptional sturdiness, corrosion resistance, and durability, effectively capturing debris while withstanding the impact of high-velocity fluid flows.
Low Flow Resistance & High Efficiency: Engineered with an optimized internal flow path, the strainer minimizes pressure drop across the pipeline. This low flow resistance ensures that the overall system efficiency is maintained, reducing energy consumption for water supply pumps.
Large Dirt Holding Capacity & Convenient Blowdown: The Y-shaped configuration is specifically designed to accumulate a significant amount of impurities before requiring maintenance. When cleaning is necessary, the blowdown process is straightforward and convenient, significantly reducing system downtime and maintenance labor costs.
Customizable Screen Mesh Sizes: To accommodate diverse project requirements, the mesh size of the filter screen can be customized. Whether you need coarse filtration for large debris or fine filtration for smaller particles, the strainer can be tailored to suit specific medium conditions.
As an indispensable filtration device in medium conveyance pipeline systems, the Y-type strainer is typically installed at the inlet end of critical components such as pressure reducing valves, pressure relief valves, constant level valves, and water pumps. By effectively removing solid impurities from the fluid, it prevents scoring, clogging, and premature wear of sensitive valve internals and associated equipment. This proactive protection not only extends the service life of your pipeline infrastructure but also ensures the continuous, safe, and efficient operation of the entire fluid management system.
