China Y-Strainer (WYE Type) for Chemicals, Air, Water, Steam, Oil - PN10/PN16 Suppliers & Factory
The Y-Strainer is a vital component used to protect pipeline equipment such as valves, pumps, and flow meters from damage caused by debris or solid particles. Designed with a Y-shaped body, it effectively captures contaminants while allowing the fluid to pass through, ensuring cleaner flow and extended system life.
As one of China's trusted valve and pipeline component suppliers, we offer Y-strainers made from high-quality materials such as cast iron, ductile iron, stainless steel, and bronze. These strainers are suitable for water treatment plants, oil pipelines, HVAC systems, and general industrial applications.
Each Y-strainer includes an accessible screen chamber for easy cleaning and maintenance, reducing downtime and improving efficiency. Available in flanged, threaded, or socket-welded end types, they provide installation flexibility across multiple systems and pressure classes.
💡 Whether you're protecting sensitive instruments or maintaining cleaner fluid systems, our Y-strainer delivers reliable performance, corrosion resistance, and cost-effective operation over time.

Frequently Asked Questions
Q What is a Y-Strainer used for?
A Y-Strainer is used to protect pipeline equipment — including valves, pumps, and flow meters — from damage caused by debris, solid particles, and contaminants in the fluid system. It captures unwanted particles while allowing fluid to flow through freely.
Q What materials are available for the Y-Strainer body?
The Y-Strainer body is available in Cast Iron and Ductile Iron. The disc can be Stainless Steel or Cast Bronze, the stem in Stainless Steel or Brass, and the seat ring in Brass — providing flexibility for different media and operating conditions.
Q What size range and pressure ratings are available?
Our Y-Strainers are available from DN50 to DN300 (and up to DN500 per the dimension table). They are rated for nominal pressures of PN10 and PN16, suitable for a wide range of industrial applications.
Q Which standards does the Y-Strainer comply with?
The Y-Strainer is designed and tested to international standards including DIN3356 (design), DIN3202 F1 (face-to-face), DIN2533 PN10/16 / ANSI 125/150 / BS4504 / JIS10K (flange drilling), and DIN3230 (test inspection).
Q What types of media is the Y-Strainer compatible with?
The Y-Strainer is compatible with a wide range of media including water, chemicals, air, steam, oil, acids, and salts. It is widely used in water treatment plants, oil pipelines, HVAC systems, and general industrial applications.
Q How do I clean and maintain a Y-Strainer?
The Y-Strainer features an accessible screen chamber that allows easy removal and cleaning of the filter screen without dismantling the entire pipeline. Regular maintenance intervals depend on the level of contamination in the fluid, but the design significantly minimizes downtime.
