Cast Iron Y Strainers

Inexpensive cast wye strainers for water and steam applications

 

Cast Iron Y Strainer, threadedCast Iron Y Strainer flangedWe offer Cast Iron Y strainers for ¼" to 24" pipeline sizes. Links to both the Keckley and Titan Y strainer catalog pages are below.  Keckley offers a broader selection of connection sizes and their Flow Coefficient (Cv) values tend to be higher than Titans.

 

Eaton acquired their cast iron Y strainer products from the acquisition of Hayward in 2005, subsequently selling that product lie to Titan.

 

Y strainers are designed to protect downstream processes from particulate whereas simplex basket strainers are designed to continuously remove particulate.  To better understand the differences and evaluate which is better for your application please refer to our article SIMPLEX STRAINERS: Differences between Y and Basket Style Strainers for additional information.

 

The Cv is an indication of the resistance to flow, thus the higher the Cv, the higher the flow capacity.  Often looked at another way, the strainer having a higher Cv will have a lower differential pressure drop, thus you can use the Cv value to compare "performance" between different models.

 

The percentage difference in the Cv value is the approximate percentage difference in flow rate capacity and pressure drop; it is not an exact correlation but if you compare a Keckley 2" threaded Style B with Cv of 98 to the Titan 2" threaded Style 12 with Cv of 70, the Keckley model is significantly different.  Comparing the 3" sizes (Cv 161.3 vs. Cv 160) you would consider those equivalent from a performance perspective.

 

Does Cv matter for your application?  That depends upon your flow rate and your sensitivity to differential pressure.  Generally speaking the lower the initial clean differential pressure, the longer the duration between screen cleaning, so that might add-up annually to be significantly less cleaning activities.  Then again, if there's hardly any particulate anyway, you might not notice any difference at all.

 

Cv matters most when you are pushing the flow rate limit for your pipeline OR when your system is very sensitive to differential pressure; so a Y strainer installed on the suction side of a pump or blower would benefit from the model with the higher Cv value.

 

This is why purchasing from general resellers is tricky, because Y strainer performance is not dictated by its connection size and type alone.

 

The differential pressure calculator below is based upon the Keckley models and you can calculate the approximate clean differential pressure drop by selecting the strainer connection size, inputting your flow rate (GPM), inputting the specific gravity if other than water (sg of water = 1) and select the viscosity range if other than water (SSU of water = 30).  Click "Update" to refresh the data and be sure that the clean differential is ≤2 PSI for the intended basket retention.

Use the following formula to compare the initial clean differential pressure of strainer models using their Cv values:

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

Pressure Drop Formula

To compare the maximum flow rate (capacity) between strainer models use the following formula:

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

Maximum capacity for a strainer 

Put away your calculator!  That's what we are here to do, assist you!  Simply fill-out our Y strainer inquiry form and we will select the most appropriate model, advising pricing and lead time.  When either brand is acceptable, we'll quote both so you can decide which you prefer.
