Ductile Iron Y-Type Strainer (Grooved/Flanged Pipe Strainer)
The Y-Type Strainer is an indispensable filtration device for piping systems, designed to remove mechanical impurities from fluids to protect pumps, valves, and other equipment from damage. Our Y Strainer is manufactured from high-strength ductile iron, offering superior pressure resistance and long-term durability.
Whether you need a Grooved Y-Strainer for fire protection or a Flanged Y-Type Strainer for industrial water treatment, KOXY provides precision-engineered solutions with various Coating Options including Red Painted, Galvanized, and Epoxy Blue/Grey.
Key Features & Benefits
Low Pressure Drop Design: The optimized internal structure of our Y-type strainer ensures efficient fluid flow with minimal pressure loss.
Durable Stainless Steel Screen: Equipped with a high-quality SS304/SS316 screen, providing excellent corrosion resistance and precise filtration.
Versatile Coating Protection: Available in Red Painted for fire systems, Epoxy Blue/Grey for water supply, or Galvanized for harsh environments, ensuring maximum service life.
Easy Maintenance: The compact Y strainer design allows for quick cleaning and debris removal through the blow-off plug without disconnecting the main piping.
Robust Ductile Iron Body: Offers higher impact resistance and tensile strength than traditional cast iron strainers, ensuring safety in high-pressure applications.
