Cast Bronze Y Strainers

Lead-Free Wye Strainers for Seawater, Potable Water & Steam

 

Our cast bronze Y strainers cover ¼" to 12" pipelines. Keckley offers the broadest selection, including ANSI flanged versions. Titan is limited to threaded and solder-end connections up to 3". Eaton originally acquired its bronze Y strainer line from Hayward in 2005 and later sold it to Titan.

 

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

 

Blow-Down Capability

A manual or automated valve can be attached to the drain port for “blow-down” of retained material. Effectiveness depends on the nature of the particulate and whether it is embedded in the screen. Blow-down works best with relatively few, hard particles (the original design intent was steam systems and pipe scale). Some customers also use it successfully with water and other fluids.

 

For applications that need both larger open area and flushing capability, see our Flushing Strainers page.

 

Flow Coefficient (Cv) Differences

Keckley’s bronze Y strainers have significantly higher Cv values than Titan’s, except in the 3" size where they are the same. Higher Cv means lower differential pressure at a given flow rate (or higher flow at a given ΔP).

 

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

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

Cv is especially important on the suction side of pumps or blowers and whenever the system is sensitive to pressure drop. Do not assume that same-size strainers will perform the same.

Pressure Drop Calculators

Two interactive calculators cover the main Keckley cast bronze models. Select connection size, enter flow rate (GPM), adjust specific gravity and viscosity if needed, then update. Target a clean differential of ≤ 2 PSI.
