316SS Y Strainers

 

316SS Y StrainerWe offer 316SS Y strainers for ¼" to 24" size pipelines from three manufacturers, Eaton, Keckley and Titan.  Titan offers the broadest number of connection sizes and pressure classes, closely followed by Keckley.  Eaton is limited to the most common pressure classes: 600# threaded/socket and the 150/300# class ANSI flanged models.

 

Although often a brand is chosen based upon price and lead time, be careful!  Just because strainers have the same connection size does not mean they will perform the same.

 

Comparing strainer Flow Coefficient Values (Cv)

The Cv value is an expression of the "flow resistance" for strainers and other pipeline components and this value can be used to calculate the differential pressure for a given flow rate.  The the following formula can be used to calculate the differential pressure for your flow rate:

 

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

Flow Coefficient Formula

 

Using a size and pressure class all three manufacturers have in common, here's how their different Cv values effect performance:

 

2½" 150# flanged Y 316SS strainers Eaton Keckley Titan
Model 85 Model SSA7 YS61
Cv: 105 98 110
Max. Flow with 2ΔPSIG: 148 GPM 138 GPM 155 GPM
ΔPSIG with 100 GPM flow rate: 0.9 1.0 0.8
List Price: $1995 $1954 $1477

 

In this case the Titan brand performs the best and costs less than Eaton and Keckley, however this is not always the case.  We encourage customers to fill-out our Y strainer inquiry form, which prompts you to provide the relevant design criteria.  Upon receipt, often within an hour or so, we review your options and provide a proposal for the most suitable model. Using the example table above, if you inquired about a Keckley brand, we might suggest Titan as an equivalent or better design for a reduced cost.  The Cv values are not always as close as they are in our example, so if your application involves protecting the suction line to a centrifugal pump or another process sensitive to pressure drop, it is a good idea to compare the performance of different models.

 

A Y strainer is a type of simplex strainer and designed only for protecting equipment and processes downstream from particulate whereas a basket strainer is designed to continuously remove particles.  To better determine which style strainer is best for your application, refer to our article SIMPLEX STRAINERS: Differences between Y and Basket Style Strainers.

 

Please feel free to contact us via phone or email with assistance in selecting the best Y strainer for your application.  At that time we can also confirm availability and pricing based upon the screen size desired.
