Stainless Steel ANSI 150lb Flanged Y Strainer

The Stainless Steel ANSI 150lb Flanged Y Strainer is equipped with a reinforced stainless steel filter screen, which effectively intercepts impurities, protecting pumps, valves, and instruments. It features stable pressure resistance, excellent filtration performance, and easy disassembly and cleaning. As a direct factory source, we offer high-quality, cost-effective factory prices with highly competitive pricing.

Structural and Performance Advantages

The Stainless Steel ANSI 150lb Flanged Y Strainer adopts a one-piece Y-shaped streamlined shell structure, ensuring smooth fluid flow and low pressure drop. Equipped with a high-precision stainless steel filter, it accurately captures welding slag, rust, silt, and impurities. Installed upstream of pumps, valves, instruments, and heat exchangers, it effectively protects downstream equipment from erosion, blockage, and wear, extending the service life of the entire piping network.

Material and Standard Compliance

Valve body materials include WCB carbon steel, 304 (1.4301), and 316L (1.4404) stainless steel, offering excellent high-temperature resistance, corrosion resistance, and stable pressure resistance. The flange sealing surface uses an RF raised face, with dimensions fully compliant with ANSI 150 lb standards, ensuring precise installation and reliable sealing. It is suitable for various operating conditions including oil, steam, water, and chemical media. The filter screen supports multiple mesh sizes, offering high dirt-holding capacity, reinforced structure, and erosion resistance. It is easy to disassemble and clean, facilitating daily maintenance and is reusable.

Customizable Filtration Grades:

1. Coarse Filtration (10-40 mesh): Intercepts large particulate impurities, protecting pumps, main valves, and main pipeline equipment.

2. Standard Filtration (60-100 mesh): Suitable for general water supply and drainage, HVAC, fire protection, and oil pipelines.

3. Fine Filtration (120-300 mesh): Suitable for pre-filter protection in pure water, pharmaceuticals, fine chemicals, and precision equipment.

Quality Control and Supply Capability

Each Stainless Steel ANSI 150lb Flanged Y Strainer undergoes rigorous quality control and pressure testing before leaving the factory. We provide complete English material reports, pressure test certificates, and export documents, and support customization services for special mesh sizes, extended cylinders, and special materials. Our products are exported in large quantities to Europe, America, the Middle East, and Southeast Asia. DIYE VALVE has become a trusted and preferred supplier of ANSI standard pipeline filter accessories worldwide.

Technical Parameters

FAQs

Q: How to choose the common mesh sizes of the filter screen in the strainer?

● Coarse Filtration (10–40 mesh): Protects the main pump and intercepts large particles;

● Conventional Filtration (60–100 mesh): Universal for water supply and drainage, fire protection, and oil pipelines;

● Fine Filtration (120–300 mesh): Pre-filtration for pure water, pharmaceuticals, fine chemicals and precision equipment.

Q: How often should the filter screen of the strainer be cleaned?

A: Poor water quality with more impurities: Clean every 1–3 months;

Clean water working conditions: Maintain once every six months to one year.

Q10: What causes the strainer's flow rate to decrease and pressure drop to increase?

A: The filter screen is blocked by excessive dirt. Remove the end cover, take out the filter screen and rinse it clean to restore normal operation.

Q: What are the common pressure ratings of the strainer?

GB/DIN Standard:

● PN16 (16 bar): Conventional tap water, HVAC, fire protection, and general water supply and drainage;

● PN25 (25 bar): High-rises, high-pressure pump rooms, steam, and industrial area pipelines;

● PN40 (40 bar): High temperature and high pressure, chemical industry, and boiler front-end.

ANSI Standard:

● 150LB (Class150) ≈ PN20: General ANSI projects, petrochemicals, and water supply;

● 300LB (Class300) ≈ PN50: High-pressure oil and gas, steam, and high-pressure sections of chemical plants.
