OVERVIEW: The YFF-Lined Y (Wye) strainer is an FRP design with a PVC, CPVC, Polypropylene, or PVDF thermoplastic liner & screen for special services in a 150# Class. The composite laminate construction provides structural strength and optimizes chemical resistance. Y strainers feature a cleanout valve that eliminates the need for removing the basket when performing routine cleaning.

They are all provided with 150# flanged ends standard, but threaded and other ends are also available. Flanged or threaded blowdown ports are provided. 

If the chemical, pressure, temperature, and other pertinent information is provided, Stayflow can choose the appropriate material combination. In general, the thermoplastic linings have the following characteristics:

• Polyvinyl Chloride - PVC has excellent resistance to acids, alkalies, and salt solutions among many others. It has long life at 73°F.

• Chlorinated Polyvinyl Chloride - CPVC has similar properties to PVC at 73°F, but has a temperature correction factor that is more favorable for high temperature applications.

• Polypropylene - It is chemically resistant to many compounds, and maintains its pressure ratings at higher temperatures. It is light with good strength, and is resistant to most acids and alkalies, but should not be used with oxidizing acids, chlorinated hydrocarbons, and aromatics.

• PVDF - It is strong and abrasion resistant, and retains most of its strength to 280°F. Of all the thermoplastics, PVDF has the greatest combination of strength, chemical resistance and working pressure.

The YFF-Lined strainers utilize a screen with 1/4" perforations or as specified, that is the same material as the liner. EPDM lid gaskets come standard, with Viton and Teflon also available.

The YFF Model strainers are special FRP construction with no liners. The BFF Model and BFF-Lined Model are basket strainers of similar construction.
