Cast Carbon Steel Y Strainers

Wye Strainers for Liquid and Gas Applications

 

Our cast carbon steel Y strainers are available for pipeline sizes from ¼" to 24". Titan offers the broadest product line, including sizes larger than Keckley’s maximum of 14" and pressure classes higher than Eaton’s 300# and Keckley’s 1500# designs.

 

How to Select Which Brand

Start by narrowing options by pressure class and connection type. Eaton’s highest flanged pressure class is 300# and threaded/socket class is 600#. If you need higher ratings, the choice is between Keckley and Titan.

 

Flow Coefficient (Cv) Comparison

Cv is a performance-based comparison linked to differential pressure across the strainer body. Higher Cv means lower differential pressure for a given flow rate. The difference in performance is roughly proportional to the difference in Cv.

 

It is incorrect to assume that Y strainers of the same connection size will perform the same. This is especially important on the suction side of centrifugal pumps where differential pressure can be critical.

 

Example – 2½" 150# ANSI flanged Y strainers:

Characteristic	Eaton Model 85	Keckley Model SA7	Titan YS61
Cv	105	98	110
Max Flow @ 2 ΔPSIG	148 GPM	138 GPM	155 GPM
ΔPSIG @ 100 GPM	0.9	1.0	0.8
List Price	$1,152.58	$384.17	$896.10

In this example the lowest-priced model also has the highest Cv, but that is not always true. For 150# and 300# flanged Y strainers Titan’s Cv values are generally higher across the board. Keckley’s ¾" and 1" sizes have roughly double Eaton’s Cv and about 30% higher than Titan’s.

 

Pressure Drop & Capacity Formulas

Use these formulas to compare clean differential pressure or maximum capacity between models:

 

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

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

Y strainers protect downstream equipment from particulate. Basket strainers, with their larger open area ratio, are better suited for continuous particulate removal. See our article Differences Between Y and Basket Style Strainers for more detail.
