1. Product Introduction
Our ANSI Y-Type Strainer is a high-efficiency pipeline filtration device designed for installation upstream of pressure relief valves, pumps, and control valves. With a compact Y-shaped structure and flanged end connection, it provides low flow resistance while effectively capturing solid impurities in water, oil, steam, and other industrial media. The strainer features a removable basket screen for easy cleaning and maintenance, ensuring long-term reliable operation and protecting downstream equipment from damage. Manufactured in strict accordance with ASME B16.34 and API 598, it is available in a wide range of sizes and pressure ratings to meet diverse project requirements.
2. Key Features
✅ Low Flow Resistance & High Filtration EfficiencyY-type structure ensures smooth fluid flow and minimal pressure loss; the perforated basket screen traps solid particles effectively.
✅ Easy Maintenance & CleaningQuickly remove the screen cover and take out the filter basket for cleaning without disassembling the entire valve from the pipeline.
✅ Wide Compatibility & ApplicationSuitable for water, steam, oil, gas, and general industrial media; widely used in petroleum, chemical, power, HVAC, and municipal pipeline systems.
✅ High-Strength MaterialsBody/Bonnet options in ASTM A216 WCB, CF8, or CF8M; Screen in 2Cr13, SS304, or SS316; Plug in Carbon Steel; Gaskets in Graphite/Soft Steel/EPDM/NBR.
✅ Compliant with International StandardsDesign to ASME B16.34, Face to BS EN558, Flange to ASME B16.10, Test to API 598, guaranteeing quality and interchangeability globally.

4. Material & Structure Details
4.1 Main Material Configuration
Body & Bonnet: Choose from WCB (carbon steel), CF8 (cast stainless steel 304), or CF8M (cast stainless steel 316) for optimal pressure and corrosion resistance.
Filter Screen: 2Cr13, SS304, or SS316 mesh, offering high strength, corrosion resistance, and long service life.
Internal Plug: Carbon steel for reliable structural support and sealing cooperation.
Sealing Gasket: Graphite (high temp), EPDM (general), or NBR (oil resistance) to suit different media.
4.2 Working Principle
Fluid enters the Y-type strainer body through the inlet flange, flows through the filter basket, and solid impurities are retained on the screen. When cleaning is required, simply close the upstream valve, remove the cover bolts, take out the basket, rinse the dirt, and reinstall it. The entire process is simple and does not require special tools.
5. Application Scenarios
Petroleum & Gas Industry: Filtration of crude oil, natural gas, and refinery media.
Power Plant: Steam, feed water, and cooling water filtration in boiler systems.
Chemical & Petrochemical: Protection of pumps, valves, and instruments from solid particles.
HVAC & Building Services: Water supply, drainage, and air conditioning system filtration.
Municipal Water & Sewage: Urban water supply and sewage pipeline pretreatment.
General Industry: Machinery, mining, and textile pipeline fluid purification.

Q&A
Q1: What is the difference between WCB, CF8, and CF8M strainers?
A: WCB is carbon steel for general water, steam, and oil applications; CF8 (304) and CF8M (316) are stainless steel for corrosive media such as acid, alkali, and chemical liquids.
Q2: How often should the Y-strainer be cleaned?
A: Cleaning frequency depends on the medium’s impurity content: generally 1–3 months for general industrial water, and adjusted according to actual working conditions for corrosive or high-impurity media.
Q3: Can you provide strainers with EPDM or NBR gaskets?
A: Yes, we offer graphite, EPDM, NBR, and soft steel gaskets to meet different temperature, pressure, and medium resistance requirements.
