As a professional China GB Y strainer manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance Y-type strainers that fully comply with Chinese National Standards (GB). Our GB Y strainers are engineered to provide reliable mechanical filtration —removing unwanted solids, debris, rust, scale, and welding slag from liquid, gas, or steam lines to protect downstream equipment such as pumps, control valves, steam traps, flow meters, regulators, and instrumentation from clogging, erosion, and premature wear.
The Y strainer derives its name from its distinctive Y-shaped body configuration, where the straining element—a perforated or wire mesh screen—is housed in an angled leg that intersects the main flow path. This compact design allows for efficient filtration while maintaining a low profile, making Y strainers easy to install in tight piping configurations. When cleaning is required, simply remove the strainer cap and pull out the filter cartridge—without disassembling the pipeline.
Our GB Y strainers are manufactured in strict accordance with the relevant Chinese National Standards:

Understanding the differences between GB, DIN, and ANSI standards is crucial for proper strainer selection:
| Feature | GB Y Strainer | DIN Y Strainer | ANSI Y Strainer |
|---|---|---|---|
| Measurement System | Metric (mm, MPa) | Metric (mm, bar) | Imperial (inches, psi) |
| Design Standard | GB/T 14382-2008 | DIN EN 13709 | ASME B16.34 |
| Flange Standard | GB/T 9113 | DIN EN 1092-1 | ASME B16.5 |
| Face-to-Face | GB/T 12221-2005 | DIN 3202-F1 | ASME B16.10 |
| Test Standard | GB/T 13927-2008 | DIN EN 12266 | API 598 |
| Primary Markets | China, Asia, Belt & Road countries | Europe, Middle East | North America, global |
| Design Philosophy | Full bore, high flow capacity | Compact structure | Versatile |
| Interchangeability | Not compatible with DIN/ANSI without adapters | Not compatible with GB/ANSI | Not compatible with GB/DIN |
GB Y-strainers follow Chinese national standards and focus on high flow with full bore design, while DIN Y-strainers follow European standards with a compact structure and versatile connection sizes. GB flanges are not directly interchangeable with DIN or ANSI flanges without special adapter flanges or gaskets. This makes it essential to specify the correct standard when procuring strainers for GB-compliant piping systems.
Our GB Y strainers are engineered with precision and reliability in mind:
Full bore design —The flow area of the filter screen is two to three times the nominal diameter, ensuring high flow capacity and minimal pressure loss
Double-layer stainless steel screen —Strong and durable, low flow resistance, easy to discharge, large pollutant-holding volume
Quick maintenance —Screen removal and cleaning without pipeline disassembly; routine maintenance takes just minutes
Drain plug / blow-off connection —Allows flushing or cleaning without removing the strainer from the line
Telescopic option available —Combines Y strainer with expansion joint for adjustable installation length, making it flexible for different engineering requirements
Wide material selection —Carbon steel, stainless steel, cast iron, ductile iron, bronze/brass options to suit different media
GB Y strainers are indispensable across multiple industrial sectors:
Oil & Gas —Pipeline systems, refineries, petrochemical pipelines
Chemical & Petrochemical —Corrosive media handling, process protection
Water & Wastewater Treatment —Industrial water treatment, cooling water systems, boiler feed water filtration, municipal water plants and sewage treatment plants
Power Generation —Steam systems, condensate lines, cooling water
HVAC & Building Services —Heating and cooling systems, air conditioning systems
Food & Pharmaceutical —Sanitary applications with GMP-grade stainless steel filters
Metallurgy —Industrial filtration
At Yuanjd Valve, we combine decades of manufacturing expertise with advanced production facilities and rigorous quality control systems.
