Cast Iron Y Strainers

Inexpensive Cast Wye Strainers for Water and Steam Applications

 

 We offer cast iron Y strainers for ¼" to 24" pipelines. Keckley provides a broader selection of connection sizes and generally higher Flow Coefficient (Cv) values than Titan. Links to both manufacturers’ catalog pages are at the bottom of this page.

Eaton originally acquired its cast iron Y strainer line from Hayward in 2005 and later sold that product line to Titan.

 

Y strainers protect downstream equipment from particulate. Basket strainers, with their larger open area ratio, are better suited for continuous particle removal. See our article Differences Between Y and Basket Style Strainers for guidance on which style fits your application.

 

Why Cv Matters

Cv indicates resistance to flow. A higher Cv means higher flow capacity and lower differential pressure. The percentage difference in Cv is a good approximation of the difference in capacity and pressure drop.

 

Example: a Keckley 2" threaded Style B (Cv 98) is significantly different from a Titan 2" threaded Style 12 (Cv 70). In the 3" sizes (Cv 161 vs. 160) the models are essentially equivalent from a performance standpoint.

 

Cv matters most when you are near the flow limit of the pipeline or when the system is sensitive to pressure drop (for example, on the suction side of a pump or blower). A higher-Cv model usually means longer intervals between screen cleanings.

 

Use the calculator to estimate clean differential pressure. Select the connection size, enter flow rate (GPM), adjust specific gravity and viscosity if needed, then update. Target a clean differential of ≤ 2 PSI.

 

Formulas for comparing models using published Cv values:

(Q = Flow rate in GPM, ΔP = calculated differential pressure)

(ΔP = maximum acceptable clean differential pressure; industry standard = 2 PSIG)
