Model CYS is a flange x flange end wye strainer. The cast iron wye strainer has standard ANSI Class 150 pound flange ends that can be connected to a lug type butterfly valve for throttling/isolation. The wye strainer comes standard with a stainless steel filter element, two 1/4" plugs, a 1/2" plug, a plugged 3/4" blow-off connection, and a flanged blow-off cover with an EPDM O-ring.

Stainless steel screen aids in filtering dirt, rust, and debris in the piping system and may be removed for cleaning

Raised-face flange ends aids in tight coupling with gaskets to provide maximum resistance to leakage

Large steel strainers/filters are not measured in mesh such as smaller strainer screens are. Large strainers are measured in perforations as mesh strainer screens are not sturdy enough to handle the high flow rates. Please note the diameter of the strainer holes and distance between them.
